Petrogenesis of Jurassic granitic rocks in South China Block: Implications for events related to subduction of Paleo-Pacific plate

Open Geosciences
Frequent magmatic intrusion and eruption during the early Yanshanian in South China formed a unique and diverse igneous rock assemblage, mainly comprising granite, rhyolite, and some basic rocks.

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 ...

Climate and Tectonic Forcing of Depositional Evolution in the Southern North China Basin Since ∼3 Ma

Geochemistry, Geophysics, Geosystems
Marginal basins provide sensitive yet incomplete records of climate and tectonic forcing, and the southern North China Basin provides an ideal setting to decode these interactions since the late Pliocene.

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.

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.

Tectonic setting of the Taltson magmatic zone at 1.9–2.0 Ga: a granitoid-based perspective

, 2000
The Paleoproterozoic Taltson magmatic zone is one of the key tectonic features of western Laurentia. The existing tectonic model for the belt envisions its formation by subduction of oceanic crust beneath a continental margin, followed by direct ...
