Experimental Study on the Mining-Induced Water-Resistance Properties of Clay Aquicludes and Water Conservation Mining Practices

Advances in Civil Engineering, 2021
The Yushen mining area contains thin bedrock and a shallow buried coal seam, where JingLe group Hipparion clay and Lishi loess serve as a high-quality cement insulation cover.

Oligocene-miocene mammalian fossils from Hongyazi Basin and its bearing on tectonics of Danghe Nanshan in northern Tibetan plateau. [PDF]

PLoS ONE, 2013
A shortage of Cenozoic vertebrate fossils in the Tibetan Plateau has been an obstacle in our understanding of biological evolution in response to changes in tectonism, topography, and environment.

Perissodactyl diversities and responses to climate changes as reflected by dental homogeneity during the Cenozoic in Asia. [PDF]

Ecol Evol, 2020
Three patterns of premolar molarization play an important role in perissodactyl diversity coupled with global climate change during the Cenozoic in Asia. In addition, the hypothesis of the “Ulan Gochu Decline” is proposed to designate the most conspicuous decrease of perissodactyl diversity that occurred in the latest middle Eocene rather than at the ...

Three-dimensional geometric morphometric analyses of humerus ecomorphology: New perspectives for paleohabitat reconstruction in carnivorans and ungulates. [PDF]

Anat Rec (Hoboken)
Abstract Long bone ecomorphology has proven effective for paleohabitat reconstructions across a wide range of mammalian clades. Still, there is no comprehensive framework to allow interpretation of long bone morphological variation within and between different monophyletic groups.

The last North African hipparions – hipparion decline and extinction follows a common pattern

Neues Jahrbuch für Geologie und Paläontologie - Abhandlungen, 2022
Research on the Algerian localities of Ain Boucherit and Ain Hanech led to the dating of the oldest stone tools in North Africa, but also to the recovery of new material of the rare three-toed horse Hipparion ambiguum (Equidae) from its type locality of Ain Boucherit and the dating of the youngest North African hipparion record at Ain

Paleodietary and Paleoclimatic Reconstruction of Hipparion Fauna at ∼9 Ma From the Xunhua Basin on the Northeastern Tibetan Plateau

Frontiers in Earth Science, 2021
Stable isotope analysis is pivotal for investigating the paleodiet and paleoecology of ancient mammals. Recently, a ∼9-Myr-old Hipparion fauna was discovered at an elevation of ∼2,200 m above sea level (a.s.l.) in the Xunhua Basin on the northeastern ...

The Miocene: The Future of the Past

Paleoceanography and Paleoclimatology, Volume 36, Issue 4, April 2021., 2021
Abstract The Miocene epoch (23.03–5.33 Ma) was a time interval of global warmth, relative to today. Continental configurations and mountain topography transitioned toward modern conditions, and many flora and fauna evolved into the same taxa that exist today.

A Simulation Study on the Spatial‐Temporal Characteristics of Pore Water Pressure and Roof Water Inrush in an Aquiclude

Shock and Vibration, Volume 2021, Issue 1, 2021., 2021
As the working face advances, the overlying aquiclude is subjected to periodic dynamic loads, causing pore water pressure distortion, which provides important forewarning for a water inrush disaster in shallow coal seams. In order to analyze the pore water pressure in an aquiclude and determine the spatial‐temporal characteristics of the water inrush ...

An Empirical Shear Model of Interface Between the Loess and Hipparion Red Clay in a Loess Landslide

Frontiers in Earth Science, 2022
Quaternary loess is widely distributed over the tertiary Hipparion red clay on the Loess Plateau of China. Large-scale loess landslides often occur along the weak contact interface between these two sediment materials. To investigate the failure mode and
