Review on disaster-prone basaltic geological bodies and fiber utilization technologies

Zhongguo dizhi zaihai yu fangzhi xuebao
Basaltic disaster-prone geological bodies are widely developed across China and have historically resulted in significant mass casualties. This paper summarizes the types and causative mechanisms of disasters based on representative examples, including ...

Geologic, geochemical, and geophysical consequences of plume involvement in the Emeishan flood-basalt province [PDF]

Geology, 2004
Prevolcanic kilometer-scale lithospheric doming in the Emeishan large igneous province, southwest China, allows us to evaluate the spatial and temporal consequences of uplift on the paleogeography, geology, geochemistry, and geophysics of the region. Systematic spatial variations are observed across the domal structure in the distribution and thickness

Early Cretaceous high-Ti and low-Ti mafic magmatism in Southeastern Tibet: Insights into magmatic evolution of the Comei Large Igneous Province [PDF]

, 2018
The Dala diabase intrusion, at the southeastern margin of the Yardoi gneiss dome, is located within the outcrop area of the ~ 132 Ma Comei Large Igneous Province (LIP), the result of initial activity of the Kerguelen plume.

New insights into the petrogenesis of the Jameson Range layered intrusion and associated Fe-Ti-P-V-PGE-Au mineralisation, West Musgrave Province, Western Australia [PDF]

, 2016
The Mesoproterozoic Jameson Range intrusion forms part of the Giles Complex, Musgrave Province, Western Australia. It is predominantly mafic in composition comprising olivine-bearing gabbroic lithologies with variable amounts of magnetite and ilmenite ...

Magmas Erupted during the Main Pulse of Siberian Traps Volcanism were Volatile-poor [PDF]

, 2011
The eruption of the Siberian Traps Large Igneous Province (SLIP) at the Permo-Triassic boundary was synchronous with environmental degradation and the largest known mass extinction in the geological record.

Evolution of the Paleo–Tethyan Ocean between the South China and Indochina Blocks: Insights from the Babu Ophiolite in Southwestern China [PDF]

Lithosphere
The Paleo–Tethyan Ocean in Southeast (SE) Asia is generally considered to be primarily represented by the Jinshajiang–Ailaoshan suture between the South China and Indochina Blocks.

A geomagnetic polarity timescale for the Permian, calibrated to stage boundaries [PDF]

, 2016
The reverse polarity Kiaman Superchron has strong evidence for at least three, or prob ably four, normal magnetochrons during the early Permian. Normal magnetochrons are during the early Asselian (base CI1r.1n at 297.94+0.33 Ma), late Artinskian (CI2n at

Flood basalt-related Fe–Ti oxide deposits in the Emeishan large igneous province, SW China

Lithos, 2010
In the Panzhihua–Xichang region (Sichuan Province, SW China), there are a number of world-class magmatic Fe–Ti oxide deposits. They are hosted as conformable masses in lower parts of layered mafic–ultramafic intrusions that are part of the end-Guadalupian (∼ 260 Ma) Emeishan large igneous province.

Mantle-derived magmas and magmatic Ni-Cu-(PGE) deposits [PDF]

, 2005
Magmatic Fe-Ni-Cu ± platinum-group element (PGE) sulfide deposits form when mantle-derived mafic and ultramafic magmas become saturated in sulfide and segregate immiscible sulfide liquid, commonly following interaction with crustal rocks.
