Petrography and geochemistry of alkaline rocks from Michni (Warsak) area, NW Himalayas, Pakistan: Insights into petrogenesis and tectonic setting

Solid Earth Sciences
The Michni area within the Warsak complex that is part of the Peshawar plain alkaline igneous province (PPAIP) in NW Pakistan, hosts a diverse suite of alkaline and carbonatitic rocks whose origin and evolution remain poorly constrained.

Lithospheric Architecture and Mantle Metasomatism Linked to Iron Oxide Cu‐Au Ore Formation: Multidisciplinary Evidence from the Olympic Dam Region, South Australia

Geochemistry, Geophysics, Geosystems, 2018
The role of lithospheric architecture and the mantle in the genesis of iron oxide copper‐gold (IOCG) deposits is controversial. Using the example of the Precambrian Gawler Craton (South Australia), which hosts the giant Olympic Dam IOCG deposit, we ...

Constraints for post-orogenic extension of the northern margin of the Qaidam Basin from the Late Silurian–Late Devonian igneous rocks in the Gahai–Nanshan area

Dizhi lixue xuebao
Objective  The northern margin tectonic zone of the Qaidam Basin underwent a transition from oceanic subduction to continental subduction during the Early Paleozoic, resulting in the formation of the ultrahigh-pressure metamorphic zone known as the ...

Provenance Analysis Based On Petrographic Samples On EXIA-1 Well, Banggai Basin, East Sulawesi, Indonesia

JGEET: Journal of Geoscience, Engineering, Environment and Technology
The structure of Exia is composed of Miocene built-up carbonates formed by shear faults. The buildup carbonate feature in the Exia prospect can be seen from the high elevation surrounded by lows with an NNE-SSW and NE-SW trending.

Petrogenesis and tectonic setting of the Yushishan and Yueyashan ophiolites in the Beishan orogenic belt, China: constraints on the evolution of the southern margin of the middle Paleo-Asian Ocean in early cambrian

Frontiers in Earth Science
The occurrence of ophiolites in the Beishan Orogenic Belt (BOB), located in the southern Central Asian Orogenic Belt (CAOB), is critical for elucidating the tectonic evolution of the southern part of the Paleo-Asian Ocean (PAO).
