The Middle Karoo deposits of the onshore Tanga Basin of northern coastal Tanzania contain dark grey-black, fossiliferous organic-rich rocks outcropping at Kakindu and Pangarawe areas. Deposit types, depositional and post-depositional processes, conditions and features characterising these rocks are poorly understood. This work used core logging, ou...
The December 3rd 2023 catastrophic landslide which claimed 89 lives in the Hanang Town in Northern Tanzania is undeniable fact of how deadly the landslide can strike. Geological fieldwork, structural measurement, and SRTM-DEM data reveal that the Hanang area is located within a tectonically active zone of the East African Rift System where the inte...
Carbonates in the system Na2CO3-CaCO3 are nowadays suggested as having a wide stability field at conditions of the mantle transition zone. Our structural analysis of nyerereite, which has limited stability fields at ambient conditions, and its similarities with already known carbonates that are stable at high-pressure conditions, allowed us to prop...
Over the past two decades, multidisciplinary studies have unearthed a rich history of volcanic activity and unrest in the densely-populated East African Rift System, providing new insights into the influence of rift dynamics on magmatism, the characteristics of the volcanic plumbing systems and the foundation for hazard assessments. The raised awar...
Volatiles, such as carbon and noble gases, are continuously degassed from Earth's mantle and crust to Earth's surface in continental rifting systems. Here, we present He-Ne-Ar abundances and isotopes as well as major gas chemistry (CO2, He, Ar and CH4) data for (n = 13) naturally-degassing seeps in the Rungwe Volcanic Province (RVP) of the East Afr...
Volatile elements are concentrated at Earth's surface, forming a rich atmosphere and oceans which enabled the eventual emergence of life. However, volatiles are also abundant in solid Earth reservoirs, such as the crust and mantle, and these reservoirs play a key role in moderating volatile movement throughout the planet. Continental cratons repres...
Constraining the architecture of complex 3D volcanic plumbing systems within active rifts, and their impact on rift processes, is critical for examining the interplay between faulting, magmatism and magmatic fluids in developing rift segments. The Natron basin of the East African Rift System provides an ideal location to study these processes, owin...
The mineralogy of Gokona and Nyabigena gold deposits in Tanzania have been studied using Short Wavelength Infrared (SWIR) Spectrometry technique with an aim to fingerprint hydrothermal system responsible for the formation of the deposits and establish pertinent mineralogical signatures for gold deposition. Gokona and Nyabigena deposits are hosted i...
Continental rifts are important sources of mantle carbon dioxide (CO2) emission into Earth’s atmosphere1–3. Because deep carbon is stored for long periods in the lithospheric mantle4–6, rift CO2 flux depends on lithospheric processes that control melt and volatile transport1,3,7. The influence of compositional and thickness differences between Arch...

Combinations of geological, geophysical and geochemical techniques have been used to explore for gold deposits at Misaki within the Iramba-Sekenke Greenstone Belt in Singida region. The Misaki area is occupied by different rocks including homogeneous coarse-grained granite containing numerous xenolit...
This study presents the use of geological remote sensing and geochemistry to determine spatial extents, geochemical characteristics and petrogenetic origin of Ndanda-Masasi metagranitoids in order to explore for important metals (Sn, W, Ta and Nb) in the metagranitoids. Geological remote sensing was done using Advanced Spaceborne Thermal Emission a...
Oldoinyo Lengai is the only volcano on Earth currently erupting natrocarbonatites, of which the source and genesis remain controversial. Cognate xenoliths and fumaroles were sampled at the summit of Oldoinyo Lengai, and deep crustal xenoliths from Oltatwa maar, in 2010 and 2014, after the 2007-2008 sub-Plinian eruption. The summit cognate xenoliths...
The levels of toxic metals in sediments and soils along high traffic Sam Nujoma highway and in the densely populated Sinza area in Dar es Salaam Tanzania were determined using portable X-ray fluorescence spectrometer (pXRF) and atomic absorption spectrometer (AAS) in order to assess the levels of the metals in the sediments and soil and evaluate th...
The age of gold–copper–lead mineralization in the Katuma Block of the Ubendian Belt remains controversial because of the lack of radiometric ages that correlate with the age of tectonothermal events of this poly-orogenic belt. Previous studies reported whole rock and mineral Pb–Pb ages ranging between 1,660 and 720 Ma. In this study, we report U–Th...
LA-ICP-MS U-Pb zircon geochronological and geochemical data of meta-igneous and metasedimentary rock types of the Katuma Block of the Paleoproterozoic Ubendian Belt in Tanzania are used to unravel the crustal evolution of this metalliferous terrain. The protoliths of the metabasites and orthogneisses previously considered to be Paleoproterozoic are...
Modern and ancient active continental margins are well known for their potential for hosting important gold deposits. The Neoarchean Musoma-Mara Greenstone Belt of the Tanzania Craton is also known for hosting several important gold deposits. Previous geochemical studies of the belt demonstrated that the rocks formed along Neoarchean convergent mar...
The Atlas of gold deposits in Tanzania reviews the geology of significant gold deposits in Tanzania taking into account the new information collected from the exploration and mining companies and research work done in the gold producing regions. The emphasis is placed on the nature and composition of the ore and the geological setting of each of th...
A combination of Short Wavelength Infra red (SWIR) spectral and multielement analyses was used to characterize certain hydrothermal alteration, pathfinder elements and their distribution within gold deposits in the Archean Musoma- Mara greenstone belt in Tanzania. The aim was to fingerprint hydrothermal systems responsible for the formation of majo...
