Introduction
My research utilises igneous petrology (microscopy and petrography) and geochemistry (SEM, EPMA, XRF, ICP-MS, TIMS) to understand the style of tectonics that operated on the Early Earth and the petrogenesis and geodynamic settings of a wide variety of extrusive and intrusive igneous rocks. I am interested in studying the petrogenesis and tectonic setting of Archaean to Phanerozoic igneous rocks and their implications for the evolution of the Earth's crust and mantle.

Numerous W-Sn deposits are developed in the South China Block with the majority related to the Yanshanian
(Jurassic to Cretaceous) granites; a smaller number of deposits have been found associated with Kwangsian
(middle Paleozoic) granites, the largest of which is the Niutangjie skarn W deposit. The Niutangjie deposit is
spatially associated with t...
The 2722 ± 2 Ma Archaean megacrystic anorthosite-bearing Haines Gabbroic Complex in the Wawa subprovince of the western Superior Province formed contemporaneously with the spatially associated Greenwater Assemblage of the Shebandowan greenstone belt, Ontario, Canada. Both field and petrographic observations indicate that the Haines Gabbroic Complex...
This study presents extensive new field, petrographic, and whole-rock major and trace element and Sm–Nd and Pb isotope data for the Neoarchean megacrystic anorthosite-bearing Bird River Sill, spatially associated Neoarchean supracrustal rocks of the Bird River greenstone belt, and the Mesoarchean Maskwa Lake TTG Batholith I, Manitoba, Canada. Field...
The volcanic landscapes of Madeira, part of the Madeira Archipelago in the NE Atlantic Ocean, form arguably the defining
features of the island. The volcanic landscapes occur in the geoheritage sites of Madeira compiled by Sotiriou and Nunes
(2024), and include those in the scenic viewpoints in the Ponta de São Lourenço, Porto da Cruz, São Vicente...
In a paper in 1970, Brian Windley first recognised that early terrestrial and lunar anorthosites both have calcic plagioclase, and low TiO2 and high CaO and Al2O3 contents. Despite these similarities, the geochemistry of early terrestrial and lunar anorthosites has not been rigorously compared and contrasted. To this end, we compiled 425 analyses f...
The island of Madeira forms part of the Madeira Archipelago, an Autonomous Region of Portugal, in the NE Atlantic Ocean. The Madeira Archipelago was built on 140-million-year-old oceanic crust. The exposed geology of Madeira is comprised of the Miocene (> 5.6 million years old) Basal (Inferior), Pleistocene-Miocene (1.8–5.6 million years old) Inter...
In this study, we integrated extensive field, petrographic, whole-rock major and trace element, and Nd–Pb–Sr–O isotope, and zircon U–Pb ages, trace element and Lu–Hf isotope data from the Neoarchean Shawmere Anorthosite Complex and surrounding gneisses to unravel their petrogenetic origin and tectonic history. The ~2765 Ma Shawmere Anorthosite Comp...
The geochemistry of Archean anorthosite-bearing layered intrusions has major implications for the thermal and chemical state of the Archean crust/mantle system, as originally posited by Bowen (1917) as “the anorthosite problem” and expanded on by Ashwal (1993). Debates have centred on the nature of the parental magmas, emplacement mechanisms and ge...
The recognition of unconformities is important for stratigraphic subdivision and correlation and for determining the timing of tectonic activity and the ocean‐continent transition process. Here, we have identified a Late Palaeozoic disconformity in the Moqinwula area of the northern Junggar Block, NW China. Integrated field relationship observation...
Petrologists are still trying to solve the ‘anorthosite problem’, which was first identified by N.L. Bowen in 1917
and revolves around the uncertainty surrounding the petrogenesis, tectonic setting, emplacement, and parental
magma compositions of anorthosites. Anorthosites are volumetrically minor to significant, occur worldwide and
have implicatio...
In this study, we applied classification and tectonic setting diagrams, N-MORB-normalised trace element, and incompatible element temporal variation diagrams, Nb/Nb*, Pb/Pb*, La/Smn, La/Nbn, Th/Nbn and Pb/Cen ratios and field-structural relationships to Archean tonalites, trondhjemites and granodiorites (TTGs) and Phanerozoic arc-generated TTGs. Ge...
The Pleistocene (2.2–1.5 Ma) Koloula Igneous Complex (KIC) on Guadalcanal in the Solomon island arc consists of a
low-K calc-alkaline sequence of ultramafic to felsic plutonic rocks. We present whole-rock major and trace element and
Sr–Nd-Pb isotope data, as well as mineral compositions that record the magmatic evolution of the complex. The intrusi...
The Neoarchean Cross Lake-Pipestone Lake terrain, northwestern Superior Province, consists of the Cross Lake greenstone belt, the Pipestone Lake anorthosite complex, and multiple generations of granitoids. The Cross Lake greenstone belt includes an assemblage of basalt, picrite, gabbro, and sedimentary rocks (Pipestone Lake Group) that formed betwe...
Temporal variations in the incompatible trace element geochemistry of volcanic rocks in Archean greenstone belts have major implications for the style of tectonics that operated in the early Earth, and if and when plate tectonic processes occurred in the Archean, which are still subjects of substantial debate. Comparing the geochemistry of Archean...
Understanding the role of southeastern Tibetan thrust faults in the development of plateau topography is key to our assessment of the geodynamic processes shaping continental topography. Detailed structural analysis along the ~400 km long Jinhe-Qinghe thrust belt (JQTB) indicates post Late Eocene thrust motion with a minor left-lateral component, i...
The Superior Province contains many fragments of Neoarchean anorthosite-bearing layered intrusions that are comprised mainly of anorthosite, leucogabbro and gabbro, with minor pyroxenite, peridotite and chromitite. Some of these major anorthosite-bearing layered intrusions include the Doré Lake, Shawmere, Bad Vermilion Lake, Pipestone Lake, Bird Ri...
Elucidating the petrogenesis and geodynamic setting(s) of anorthosites in Archean layered intrusions and Tethyan ophiolites has significant implications for crustal evolution and growth throughout Earth history. Archean anorthosite‐bearing layered intrusions occur on every continent. Tethyan ophiolites occur in Europe, Africa, and Asia. In this con...
The Harlik Mountain is in the easternmost part of the Tian Shan and is a prime exam- ple of an intracontinental orogenic belt. Several studies have used low-temperature thermochronology to understand the uplift history of this range. However, compli- cated structures have a profound impact on the study of the tectonic evolution of the Harlik Mounta...
The Neoarchean (2742.8 ± 0.8 Ma) megacrystic anorthosite-bearing Mayville layered intrusion of the Bird River greenstone belt, the Superior Province of Canada, is well preserved and well exposed. Given its good preservation, we studied the Mayville Intrusion through a combination of extensive field and petrographic observations, mineral chemistry,...
Analysing the provenance changes of synorogenic sediments in the Turpan‐Hami basin by detrital zircon geochronology is an efficient tool to examine the uplift and erosion history of the easternmost Tian Shan. We present detrital zircon U‐Pb analysis from nine samples that were collected within marginal lacustrine Middle‐Late Jurassic and aeolian‐fl...
Jurassic arc magmatic rocks are widely distributed along the Gangdese belt, southern Tibet, however, only one Jurassic arc-related porphyry Cu deposit (the Xietongmen deposit) has been found. The Jurassic arc magma fertility needs to be further constrained in order to understand the rarity of arc-related porphyry Cu deposits in this belt. This pape...
The ~2720 Ma Greenwater Assemblage of the Shebandowan greenstone belt contains anorthosites, leucogabbros and gabbros of the Haines Complex, basalts, picrites, serpentinites, gabbros, olivine websterites and harzburgites and hosts Ni-Cu-PGE-Co-Fe-Ti mineralization. All of these lithologies were metamorphosed under greenschist facies conditions and...
The 2722 Ma Haines Complex occurs in the Neoarchean (2680-2722 Ma) Shebandowan greenstone belt near the boundary between the Wawa subprovince and the metasedimentary Quetico subprovince to the north. The associated Ni-Cu-PGE mineralised Shebandowan greenstone belt consists of komatiitic to trachytic volcanics, dunitic to syenitic intrusions and met...
Optical microscope, cathodoluminescence, SEM and EPMA work and fieldwork were carried out on 10 nepheline syenite pegmatites across the Larvik Plutonic Complex (LPC) in the Vestfold and Telemark counties of southern Norway.
