Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Emeishan Basalts (SW China) and the ‘end-Guadalupian’ crisis: magnetobiostratigraphic constraints [PDF]

open access: yesJournal of the Geological Society, 2002
A magnetostratigraphic investigation of the Permian Emeishan LIP (large igneous province) was carried out on a composite section in Ebian County, close to the type area in Sichuan, SW China. The main succession of twelve flows (175 m thick) carries a normal polarity whilst the one reliable site from the overlying 30 m thick volcanic waning

A petrological experiment on Emeishan basalt: Implications for the formation of syenite from the Baima igneous complex

open access: yesTerrestrial, Atmospheric and Oceanic Sciences, 2021
The Baima igneous complex (BIC) consists of a cumulate layered gabbroic unit, an Fe-Ti oxide ore zone, and an isotropic quartz syenite. The formation of the BIC is attributed to a variety of petrological processes including: silicate immiscibility ...

Paleomagnetism and electron microscopy of the Emeishan Basalts, Yunnan, China [PDF]

open access: yesTectonophysics, 1993
Abstract Many normal and a few reversed characteristic directions of magnetization have been obtained by predominantly thermal demagnetization from ten sites of the Late Permian Emeishan Basalts collected near Kunming, Yunnan Province. The normal magnetization directions pass a fold test at the 99% confidence level and yield declination/inclination =

Geological Controlling Factors of Low Resistivity Shale and Their Implications on Reservoir Quality: A Case Study in the Southern Sichuan Basin, China

open access: yesEnergies, 2022
At the Changning block and at the Luzhou block, the genetic mechanism of low-resistivity shale and its impact on reservoir quality are currently a hot topic on a world-wide scale. Shale with resistivity lower than 20 Ω·m is widely developed at the Wufeng-

Geochemical Characteristics of Selenium in Surface Soil of Central Townships in Zhaojue County, Sichuan Province

open access: yesYankuang ceshi, 2022
BACKGROUND Selenium (Se) is one of the essential trace elements for humans, and an important way for humans to obtain and supplement selenium is by eating natural selenium-enriched agricultural products. The geochemical characteristics of selenium in the

Large igneous provinces and mass extinctions: an update [PDF]

open access: yes, 2014
The temporal link between mass extinctions and large igneous provinces is well known. Here, we examine this link by focusing on the potential climatic effects of large igneous province eruptions during several extinction crises that show the best ...

Magnetostratigraphic constraints on two‐stage eruptions of the Emeishan continental flood basalts [PDF]

open access: yesGeochemistry, Geophysics, Geosystems, 2010
Temporal and spatial variations of high and low contents of Ti basalts in the Permian Emeishan large igneous province (ELIP) of southwest China and Vietnam are crucial for modeling of continental basalt formation and the nature of mantle‐lithosphere interaction.
