Aug 1, 2015 · Numerous alkaline basaltic dykes crosscut the Early Permian Xiaohaizi wehrlite in drill-cores and syenite intrusion in the Tarim large igneous province, NW China. One basaltic dyke contains abundant clinopyroxene macrocrysts with strong resorption textures.

Apr 20, 2020 · Large igneous provinces (LIPs) can form by interactions between a hot mantle plume and the lithosphere. The Tarim LIP between ~300 and 280 Ma, located in Northwest China, has been investigated by geochemistry and sedimentology studies. However, the factors controlling Tarim LIP formation and the ancient Tarim plume characteristics remain unclear.

Nov 14, 2024 · A mantle plume, hot and buoyant materials from the core-mantle boundary, can melt the bottom of an old and stable continent (craton) and produce widely distributed flood magma on its surface. But it is still debated whether the magma activities weaken the craton or make it even stronger.

Apr 25, 2024 · Combined with previous studies, our results suggest that water plays a key role in the formation of the Tarim LIP. Additionally, the whole-rock compositions of the Akesu diabase indicate a...

Feb 1, 2025 · A mantle plume origin was invoked for the Tarim LIP, as most igneous rocks were characterized by Fe- and Ti-rich units and enriched in OIB-type trace elements (Fig. S2).

Abstract Large igneous provinces (LIPs) can form by interactions between a hot mantle plume and the lithosphere. The Tarim LIP between ~300 and 280 Ma, located in Northwest China, has been investigated by geochemistry and sedimentology studies.

Nov 1, 2010 · The Permian plumes likely played a role in late Paleozoic rapid continental crustal growth in the Central Asian orogenic belt. In addition, there appear to be two types of mantle geochemical provinces (domains) in the region, a long-term enriched Tarim province and a subduction-metasomatized and depleted Central Asian orogenic belt province.

Mar 8, 2024 · The Triassic mafic magmatism in northwest Tarim could be the product of the continuous thermal pulse of the Tarim mantle plume and be a part of the Tarim LIP. It has a source and a tectonic setting similar to those of the Tarim LIP, and both are products of the interaction between asthenospheric and lithospheric mantles in an intraplate ...

Combined with previous studies, our results suggest that water plays a key role in the formation of the Tarim LIP. Additionally, the whole‐rock compositions of the Akesu diabase indicate a...

these LIPs will contribute significantly to the understanding of mantle geochemistry and mantle plumes. The early Permian Tarim LIP (TLIP) in northwest China covers an area of more than 250,000 km2 and consists of predominant basaltic lava flows, ultramafic-mafic-
