Yo-yo tectonics occurs in wrench zones in response to switches between transpression and transtension or to changes in the geometries of faults during these modes of deformation, and involves multiple...
Fe-Cu-Ni硫化物锍在似诺里尔斯克玄武岩熔渣中界面张力大小实验研究
锍 熔渣 界面张力 铜镍硫化物矿床
2009/5/19
通过座着液滴技术, 研究锍成分变化对锍在似诺里尔斯克玄武岩岩浆中界面张力大小变化的规律. 锍的成分有两个系列: FeS-Cu2S-Ni3S2和FeO-FeS. 由实验得出如下结果: 1) 在FeS-Cu2S-Ni3S2系列中, 随着锍中Cu和Ni含量的增加, 其界面张力逐渐变小; 2) 在FeO-FeS系列中, 随着锍中氧含量增高, 其界面张力逐渐变大. 实验结果表明, 形成大规模岩浆 Cu-Ni...
中国岩浆型Ni-Cu-(PGE)硫化物矿床主要出露于中亚造山带(新疆北部的天山-阿尔泰地区)、华北克拉通北缘(吉林-辽宁-北京-河北-内蒙古)和华北克拉通西南缘(甘肃)、扬子克拉通西-北缘(陕西-四川-云南)的广大地区,受控于镁铁质-超镁铁质岩体,具有成群成带分布的特征.这类矿床依其岩石类型和地质特征可划分为3类,即产于镁铁质-超镁铁质侵入体中的基底Ni-Cu-(PGE)硫化物矿床、产于与溢流玄武...
内蒙古自治区阿拉善南部地区富Cr、Ni的斜长花岗岩体以岩基产出。代表性岩体有阿斗青—当山斜长花岗岩体和红敖包斜长花岗岩体。前者出露面积为658km~2,侵入于太古宇下阿拉善群上部岩系(Arxl~2)和古元古界上阿拉善群(Pt_1sl),被Sm-Nd等时线年龄为773.1±10.8 Ma的变质辉长岩侵入破坏(陶仙聪等,1994);后者出露面积为393km~2,侵入前震旦系,被后期岩体侵入,并被上侏罗...

Synthetic C03A12(Si04)3garnet and (Mg,Ni)3A12(Si04)3 garnet with Ni/(Ni + Mg)= 0.15-0.18 have been studied by single-crystal X-ray diffraction and optical spectroscopy. The X-ray data confirm that COH...
球粒陨石富金属Fe—Ni相的高压熔融实验与地核形成机制的探讨
熔融实验 金属Fe-Ni 地核形成
2010/12/14
选用吉林陨石富金属相,在3GPa压力、405℃～1850℃温度下,采用两种组装方式进行实验。并与先前肇东陨石全岩样的高压熔融实验进行比较。三个系列实验结果的综合对比表明,高温高压下球粒陨石中金属和硫化物经历了固相扩散、熔融和熔体聚集的过程。固相扩散使金属与硫化物彼此结合,形成了若干个小的FeNi-FeNiS二元系,使其在比Fe-Ni熔点低的温度下熔融形成Fe-Ni-S熔体。该熔体与硅酸盐熔体不相混...
