Mantle plume-lithosphere interactions beneath the Emeishan Large Igneous Province

, 2023
The input data used in our multi-observable probabilistic inversion include Rayleigh wave dispersion curves (phase_dispersion.zip), filtered elevation (elev_China_dat.xyz), filtered geoid height (geoid_China_dat.xyz), and surface heat flow (SHF_2019.txt).

Mantle hydration and the role of water in the generation of large igneous provinces

Nature Communications, 2017
The genesis of large igneous provinces (LIPs) remains controversial. Here, the authors examine the water contents of picrites from the Emeishan LIP and find that despite high water contents, the elevated temperature and trace elements suggest a mantle ...

Identifying Emeishan basalt by supervised learning with Landsat-5 and ASTER data

Frontiers in Earth Science, 2023
Multispectral-sensor images are advantageous in terms of discriminating major lithologies due to their high spatial resolution and intermediate spectral resolution, in addition to their low cost and high accessibility in comparison to hyperspectral ...

High-MgO lavas associated to CFB as indicators of plume-related thermochemical effects: the case of ultra-titaniferous picrite-basalt from the Northern Ethiopian-Yemeni plateau [PDF]

A comprehensive petrological and geochemical dataset is reported in order to define the thermo-compositional characteristics of Ti (Fe)-enriched picrite-basalt lavas (HT2, TiO2 3-7 wt%), erupted close to the axial zone of the inferred Afar mantle plume ...

Platinum-group elemental and Re-Os isotopic geochemistry of Permian Emeishan flood basalts in Guizhou Province, SW China [PDF]

, 2006
The Late Middle-Permian Emeishan continental flood basalts (ECFB) lie between the Lower Permian Maokou Formation and Upper Permian Xuanwei Formation, being part of the ~260 Ma Emeishan Large Igneous Province (ELIP) in SW China [1].

Experimental Study on the Features of Infrasonic Waves of Sandstone under Shear Load

Applied Sciences, 2021
The shear failure of rock is a major cause of rock slope instability and consequent landslides. To determine the forming mechanism of infrasonic waves during the loss of stability of sandstone slopes, experiments were carried out using a shear loading ...

The Emeishan large igneous province: A synthesis

Geoscience Frontiers, 2014
AbstractThe late Permian Emeishan large igneous province (ELIP) covers ∼0.3 × 106 km2 of the western margin of the Yangtze Block and Tibetan Plateau with displaced, correlative units in northern Vietnam (Song Da zone). The ELIP is of particular interest because it contains numerous world-class base metal deposits and is contemporaneous with the late ...
