Indentation onto Stishovite (SiO<sub>2</sub>), MgO, and a Covered Superalloy: “Pop-In” Repair, Phase-Transition Onsets, Polymorph Energies, and Transition-Energies被引量:3
《Advances in Materials Physics and Chemistry》2020年第3期77-95,共19页Gerd Kaupp 
The Berkovich indentation loading curves of the initially only extraterrestrial available polymorphs of SiO2 are physically analyzed by applying the now well established FN-h3/2 plots for conical/pyramidal indentation...

Ophiolite-Hosted Diamond: A New Window for Probing Carbon Cycling in the Deep Mantle被引量:13
《Engineering》2019年第3期406-420,共15页Dongyang Lian Jingsui Yang 
the National Natural Science Foundation of China (41720104009 and 41802034);Natural Science Foundation of Jiangsu province, China (BK20180349).
As reported in our prior work, we have recovered microdiamonds and other unusual minerals, including pseudomorph stishovite, moissanite, qingsongite, native elements, metallic alloys, and some crustal minerals (i.e., ...

Seismic detection of the X-discontinuity beneath the Ryukyu subduction zone from the SdP conversion phase被引量:2
《Earth and Planetary Physics》2018年第3期208-219,共12页QingHui Cui WenLan Li GuoHui Li MaiNing Ma XiaoYu Guan YuanZe Zhou 
supported by the China Postdoctoral Science Foundation(119103S282);National Natural Science Foundation of China(41704090,41474040 and 41504050)
The X-discontinuity,which appears at the depth of approximately 300 km,is an important seismic interface with positive velocity contrasts in the upper mantle.Detecting its presence and topography can be useful to unde...

Surface reconstruction on stishovite SiO_2,HfO_2 and rutile TiO_2 (001)
《Chinese Physics B》2011年第2期389-394,共6页汤富领 岳瑞 路文江 
supported by the National Natural Science Foundation of China (Grant No. 10964003);the Natural Science Foundation of Gansu Province (Grant No. 096RJZA102);Specialized Research Fund for the Doctoral Program of Higher Education (GrantNo. 20096201120002);the China Postdoctoral Science Foundation (Grant No. 20100470886)
This paper systematically investigates the surface reconstruction processes and patterns on stishovite SiO2, HfO2 and rutile TiO2 (001) by using classical molecular dynamics. It is found that these three surfaces re...

SiO_2 Solubility in Rutile at High Temperature and High Pressure被引量:2
《Journal of China University of Geosciences》2009年第2期274-283,共10页任玉峰 费英伟 杨经绥 白文吉 
supported by the National Basic Research Program of China (No. 2003CB716503);China Geological Survey (No. 1212010610107);the National Natural Science Foundation of International Cooperation and Communication (No. 40610098);the Laboratory Foundation of the Chinese Academy of Geological Sciences (No. JB0703)
Silicon-bearing rutile has been found in chromitite from the Luobusa (罗布莎) ophiolite, Tibet. However, the extent of SiO2 solubility in rutile and the nature of its origin are still unclear. At high pressure, SiO2...
