Magnetostratigraphic investigations on an Emeishan basalt section in western Guizhou province, China
Earth and Planetary Science Letters, 1998Abstract A magnetostratigraphic investigation has been conducted on a late Permian Emeishan basalt section at Duge in western Guizhou province, China. The characteristic remanent magnetization (ChRM) directions resolved at high temperatures from the basalts pass the fold test with dual polarity and define a normal magnetozone of five sixths of the ...

Abstract Basalts and a mafic dyke collected from the city of Panzhihua show characteristics of high-Ti and low-Ti Emeishan basalts respectively. The dyke yielded a SHRIMP zircon U–Pb mean age of 261 ± 5 Ma making it contemporaneous with the eruption of Emeishan basalts.

Study of physico-mechanical properties of Emeishan basalt saprolites in Yunnan, China
Bulletin of Engineering Geology and the Environment, 2016Saprolites are the weathered products that differ greatly from their parent rock in terms of the physico-mechanical properties because their chemical components are leached, yet differ from a typical soil because they still maintain their inherited structure. Here, typical Emeishan basalt saprolites that are widely distributed in the Guizhou and Yunnan

Abstract Based on the temporal‐spatial distribution and geochemical characteristics, the Emeishan basalts can be divided into two types: high‐P2O‐TiO2 basalt (HPT) and low‐P2O5‐TiO2 basalt (LPT), which differ distinctly in geochemistry: the LPTs are characterized by relatively high abundances of MgO, total FeO and P2O5 and compatible elements (Cr, Ni,

Three major volcanic rock sequences in the P2β formation (Emeishan basalts) were sampled during a comprehensive study of the Late Permian volcanics associated with the Panxi paleorift in southwestern China. Two of the three sections—Emei and Tangfang are composed of continental flood basalts (CFB) while the third—Ertan is an alkalic center.

The scale and characteristics of rock mass are important indexes of the rock mass structural plane classification. This paper firstly analyzes the spatial distribution characteristics, the structural plane types (original structural plane, tectonic structural plane and hypergenic structural plane) and the associated features of the Emeishan basalts and

A well-developed, 1,000 m thick basaltic sequence in the Yangliuping region, northern part of the Emeishan basalt province, includes the Lower and Middle Units of tholeiitic basalts and an Upper Unit of both tholeiites and subalkalic basalts. The basalts contain 42–55 wt% SiO2 and 4.1–8.3 wt% MgO.

Abstract Late Permian Emeishan large igneous province (LIP) developed in response to an ascending mantle plume beneath the southwestern Yangtze Craton, China. Mantle plume models predict two types of thermal effect on the lithosphere: (1) high lithospheric heat flow anomalies due to the ascending magma, and (2) heating of underlying country rocks by ...

Re–Os isotopic compositions of picrites from the Emeishan flood basalt province, China
Earth and Planetary Science Letters, 2008article i nfo Picrites from the Lijiang area, in the western part of the Emeishan flood basalt province, are considered to be one of the most important indicators of the Emeishan mantle plume, and may represent initial mantle plume activity. This paper presents the first Re-Os isotope data for picrites from the province.
