The timing of crustal melting and cooling has been investigated across the migmatites of the Greater Himalayan Crystalline Complex (GHC) in the Nyalam region, central Himalaya. Monazite U–Pb ages vary from 32 to 14 Ma and are linked to metamorphic conditions on the basis of monazite internal zoning, mineral inclusions, and changes in heavy rare ear...
Monazite is a key accessory mineral for metamorphic geochronology, but interpretation of its complex chemical and age zoning acquired during high-temperature metamorphism and anatexis remains a challenge. We investigate the petrology, pressure–temperature and timing of metamorphism in pelitic and psammitic granulites that contain monazite from the...
Modern-style plate tectonics, often characterised by subduction, is a fundamental dynamic process for planet Earth. Subduction related eclogites are widely used to indicate initiation of plate tectonics or whether different tectonic regimes dominated Earth history. However, such markers are commonly overprinted in ancient metamorphic terranes and r...
This paper introduces how crustal thickening controls the growth of the Himalaya by summarizing the P–T–t evolution of the Himalayan metamorphic core. The Himalayan orogeny was divided into three stages. Stage 60–40 Ma: The Himalayan crust thickened to ~40 km through Barrovian‐type metamorphism (15–25°C km‐1), and the Himalaya rose from <0 to ~1000...
The role of collisional belts in the global carbon budget remains controversial. Collisional orogens have traditionally been considered a net carbon sink, but recent studies have highlighted significant CO2 fluxes. The present contribution combines comprehensive field mapping with detailed petrography, pressure-temperature determination, geochemist...
The Sakarya Zone of northern Turkey contains a well-preserved Early–Middle Jurassic and Late Cretaceous submarine magmatic arc constructed over pre-Jurassic bedrocks that are considered to be the eastward extension of the Armorican Terrane Assemblage in Europe. In this study, we present U-Pb-Hf isotopic data from the detrital zircons of middle Perm...
Several giant industrial-grade rare-metal deposits have been discovered in the Himalaya most recently. However, the mechanism of how rare-metals mineralization formed in the prototype of the collisional belt is poorly understood, mainly due to insufficient studies on mineralogy, petrology and emplacement conditions. In this study, we have reported...
During the Late Cretaceous, a magmatic arc extended from the Lesser Caucasus through the northern margin of the Pontides into Srednogorie, Timok, Banat, and Apuseni (ABTS) in the Balkans for a distance of 2700 km. We studied the arc volcanic rocks in three regions in the Western Pontides and reviewed the geological data on the Lesser Caucasus-Ponti...
The Istanbul Zone (NW Turkey) forms the eastward extension of Avalonia and was subjected to deformation, uplift and erosion for a time period of 40–50 Ma following the collision with the Sakarya Zone during Early to Late Carboniferous. This paper deals with the petrology and age of the volumetrically minor basic and acidic volcanism at the lowermos...
Plate tectonics plays a critical role in modulating atmospheric CO2 concentration on the geological timescale (≥10^6year). A growing consensus on tectonic and Earth's CO2 history in the Cenozoic and deeper time provides solid restrictions and standards for testing tectonic carbon processes against global measurements. Despite this, modeling the cau...
This study deals with the age and petrogenesis of mafic-ultramafic intrusions ranging in size from a few meters to 10 km within the Early Carboniferous high-grade gneisses of the Pulur Complex in the Eastern Pontides. The intrusions comprise dunite, wehrlite, gabbronorite, leucogabbro, anorthosite and ilmenite-bearing gabbronorite of cumulus origin...
The Lhunze region of southeast Tibet uniquely juxtaposes Cenozoic granitic plutons with subvolcanic rocks in the Tethyan Himalayan Sequence. In this study, the potential petrogenetic connection between two-mica granite and subvolcanic rhyolite porphyry from the Lhunze area is investigated using petrology, geochronology, and geochemistry. Monazite T...
As the product of Himalayan orogeny, the development of the South Tibetan Detachment System (STDS) is closely related to the rise of Himalaya. Therefore, we can understand the evolution process of Himalayan orogeny through the study of STDS. Although many studies have been carried out on the STDS, there is still controversy about its formation mech...
From a metamorphic perspective, this paper introduces the research significance, a geological overview of the Himalaya, and the authors' research progress on the Himalayan collisional orogenic process in recent years. The Himalayan orogenic belt is a prototype of the continental collisional orogen in the Wilson cycle. The continental collisional pr...

Middle Permian bimodal volcanic rocks exposed in the Kocaeli Peninsula represent the first igneous event in the entire Paleozoic record of the Istanbul Zone together with coeval acidic intrusions reported from other parts of the zone. These volcanic rocks crop out as intercalations at the lower horizons of Permian-Earliest Triassic fluvial sediment...
Radiogenic isotopes of granitoids are widely applied to fingerprint the source of granitoids and study the magma mingling and assimilation processes, aiming to decipher the planetary differentiation. This weapon is based on the assumption that crustal melts inherit the radiogenic isotopes of protoliths. However, complicated melting processes in the...
Middle Permian bimodal volcanic rocks exposed in the Kocaeli Peninsula document the first igneous activity in the entire Paleozoic history of the Istanbul Zone together with coeval acidic intrusions reported from other parts of the zone. These volcanic rocks occur as intercalations within Permian-Earliest Triassic fluvial sedimentary rocks and main...
Deformation processes and rheological changes within the South Tibetan Detachment System (STDS) played a key role in accommodating exhumation of the Greater Himalayan Sequence (GHS). We present a study for the STDS in Zherger La, Yadong region, east-central Himalaya, to better quantify the spatial and temporal variations of the shear zone's interna...
Determining the geochronological framework and geochemical nature of magmatism associated with orogenic processes is crucial to establish the evolution of orogenic belts. The Himalayan orogen has recorded considerable information regarding deformation, metamorphism, and magmatism related to orogenic processes. Here, we identify four stages of grani...
High-grade metamorphic rocks and crustal melts provide crucial evidence for growth and differentiation of the continental crust, and are widespread in collisional orogens. However, their importance in the evolution of continental arcs remains poorly understood. Metamorphism and related anataxis in the preserved continental margin of the Neo-Tethys...
The continental collision between India and Asia has been ongoing since early Eocene time, but the orogenic record is typically dominated by Miocene and younger deformation and metamorphism that largely overprinted earlier Eocene-Oligocene events. This hinders our understanding of how crustal thickening responds to initial collision and when the Hi...
The Anatolide-Tauride block in the Tethyan belt represented passive northern continental margin of Gondwana throughout Paleozoic time. In this paper, we report on a relatively large amphibolite-facies metaquartz-syenite to -granite complex (~ 60 km2) in the Eastern Anatolia, the easternmost part of the Anatolide-Tauride block. Igneous textures in t...

Andalusite, as a common aluminosilicate mineral in felsic rocks, can be divided into three types: metamorphic, magmatic and peritectic. Metamorphic andalusite mainly exists in metapelite and is a product of metamorphic reactions of minerals such as muscovite, quartz, biotite and feldspar under low pressure. Magmatic and peritectic andalusite mainly...
Although the Himalayan orogenic belt is dominant by Oligocene to Miocene leucogranites, it initiated magmatic activity from middle Eocene. However, the exact distribution and genesis of early magmatism are yet to be resolved. This study identified new outcrops of middle Eocene magmatism, Haweng granodiorite porphyries, from northwest Langkazi in th...
Recent identification of tectono-metamorphic discontinuities within the Himalayan metamorphic core has challenged previous understanding of mountain-building processes/models during continental collision. However, their exact position, spatial extent, and temporal evolution still remain in debate. Monazite petrochronology and thermobarometry have b...

The formation of the Himalaya was associated with the exhumation of high-grade metamorphosed rocks of the Higher Himalayan sequence (HHS) complex, which underwent amphibolite-, granulite- to eclogite-facies metamorphism and anatexis. Occurring along the Himalayan mountain crest in the south and the Lhagoi Kangri mountain in the north, the Himalayan...
The Sakarya Zone (northern Turkey) is a Gondwana-derived continental block accreted to northern Laurussia during the Carboniferous, and is regarded as the eastward extension of Armorica. Timing of its detachment from the northern margin of Gondwana, thus opening of the Paleo-Tethys, is poorly known. Here, we report on metagranite and amphibolite wi...

Ophiolitic mélanges provide critical information on the history of subduction and metamorphism and, thus, on the evolution of ancient oceans. Blocks of mafic rocks, garnet-clinopyroxenites and amphibolites have recently been discovered in the Lhaze ophiolitic mélange of the Yarlung-Tsangbo Suture Zone, Southern Tibet. These blocks represent differe...
Widespread leucogranites in the Himalayan orogenic belt are thought to have originated by in situ partial melting of the Greater Himalayan Crystalline (GHC) when it underwent high-grade metamorphism during Cenozoic orogenesis. Therefore, the leucogranites and associated migmatites can be used to constrain the exhumation history of the GHC. However,...
In this paper, the fission track method is used to study the uplift and exhumation processes of the Himalayan orogenic belt in the Dinggye area, southern Tibet, and to explore the coupling of internal and external dynamic geological functions to shape the topography. Due to the episodic tectonic activities, the cooling and denudation of the greater...
Reconstructing the evolution of Gneiss domes within orogenic belts poses challenges because domes can form in a variety of geodynamic settings and by multiple doming mechanisms. For the North Himalayan gneiss domes (NHGD), it is debated whether they formed during shortening, extension or collapse of the plateau, and what is the spatial and temporal...
The Sikhote-Alin orogenic belt in Russian Far East is comprised of several N-S trending belts, including the Late Jurassic to Early Cretaceous accretionary prisms and turbidite basin which are now separated by thrusts and strike-slip faults. The origin and collage of the belts have been studied for decades. However, the provenance of the belts rema...
An integrated study on two subduction-related units (the Heilongjiang Complex and magmatic rocks in the Lesser Xing'an-Zhangguangcai Range) was carried out to explore the Paleozoic to early Mesozoic tectonic framework of the eastern Northeast China, with a focus on the Jiamusi block. The Heilongjiang Complex, which is considered as the suture betwe...
The Himalayan leucogranite occurs as two extensive (>1000 km) E-W trending belts on the Tibetan Plateau with the unique features. The leucogranite comprised biotite granite, two-mica/muscovite granite, tourmaline granite and garnet granite, which have been identified in previous studies, as well as albite granite and granitic pegmatite that were id...
Granite is one of the most important components of the continental crust on our Earth; it thus has been an enduring studied subject in geology. According to present knowledge, granite shows a great deal of heterogeneity in terms of its texture, structure, mineral species and geochemical compositions at different scales from small dike to large bath...
The Cenozoic Xuelong Shan antiformal dome is located along the northern segment of the Ailao Shan-Red River shear zone in Yunnan, China. Subhorizontal foliation in the gneiss core is recognized, representing a broad top-to-NE shear initiated under amphibolite facies conditions and propagating into greenschist facies in the mantling schist and strik...
We present new geochemical and geochronological data for volcanic and related rocks in the regions of the Jia–Yi and Dun–Mi faults, in order to constrain the late Mesozoic tectonic evolution of the northern segment of the Tan–Lu Fault. Zircon U–Pb dating shows that rhyolite and intermediate–mafic rocks along the southern part of the Jia–Yi Fault fo...
Northeast China is located in the eastern part of the Central Asian Orogenic Belt (CAOB) and was influenced by Paleo-Pacific subduction during the Mesozoic. Abundant granitoids from the late Paleozoic to early Mesozoic in NE China record this process, including the Khanka Lake granitoids, which resulted in extensive growth of continental crust in t...
Recent studies evoke dispute whether the Greater Himalayan Crystalline Complex (GHC) was exhumed during more than one phase. This contribution investigates the timing of ductile shear along the South Tibetan Detachment (STD), Main Central Thrust (MCT), and hidden discontinuities within the GHC of the central Himalaya. New data from the Nyalam trans...
Situated in the middle of Tethyan Himalaya, northern Himalayan granites not only better our understanding of melting behaviors and mechanism of the crust during the collisional orogenic processes, but also facilitate the investigation and evaluation of tectonic-magmatic evolution of the Himalayan orogen. In this paper, we present geochronological,...
The Paleozoic to early Mesozoic tectonic framework and evolution of Northeast China, especially the Jiamusi block and its related structural belts, are highly debated. In this paper, geochemical, geochronological and isotopic analyses were carried out on the blueschist in the Heilongjiang Complex to address these issues. The Heilongjiang Complex de...
The India-Asia collision formed the huge Himalayan orogen. The greater Himalayan crystalline complex (GHC) is the core of this orogen and its extrusion process is the key for understanding the orogeny of the Himalayas. A modified model for this extrusion is proposed based on the structural, metamorphic and geochronological studies mainly along the...
The Himalayan orogen characterized by very high variability in tectonic and climatic processes, and is thus regarded as a natural laboratory for investigating the coupling of tectonics and climate, as well as the influence of this coupling on geomorphological processes. This study uses apatite fission track (AFT) dating of samples from a 45-km-long...
A specific question about the Himalayas is whether the orogeny grew by distributed extrusion or discrete thrusting. To place firm constraints on tectonic models for the orogeny, kinematic, thermobarometric and geochronological investigations have been undertaken across the Greater Himalayan Crystalline Complex (GHC) in the Nyalam region, south-cent...
The Himalayas is a typical orogen resulted from continent-continent collision. This orogen has a complicated architecture which can be roughly divided into a southern Himalayan orogen characterized by thrusts and a northern Himalayan orogen featured by different kinds of extensional structures. All the major structures in Himalayas experienced mult...
Understanding the multiple tectonic transformations during the Himalayan orogeny is significant in evaluating the evolution of Himalayan orogen. In the Gyirong area in south Tibet, deformed leucogranitic veins in the biotite-plagioclase gneisses of Greater Himalayan crystalline complex (GHC) constitute south-vergent asymmetric folds. The reconstruc...
