黄家湾矿床是近几年在贵州遵义地区寒武系底部黑色页岩中新发现的以Ni-Mo为主的多元素矿床,本文首次对该矿床成矿阶段方解石的流体包裹体、REE和C、O同位素组成特征进行了系统研究。研究结果显示:(1)该矿床成矿阶段方解石中含有3种类型的流体包裹体:富液相气液两相水溶液包裹体;富气相气液两相水溶液包裹体;纯液相包裹体。它们的气相分数变化较大,显示成矿过程中可能发生过沸腾作用。流体包裹体的显微测温结果显...
Re-Os同位素体系被认为是岩浆Cu-Ni硫化物矿床直接定年的有力工具。通过研究世界级典型岩浆Cu-Ni硫化物矿床的Re-Os等时线表面年龄,发现有时能得到成矿年龄,有时得到与成矿年龄不一致的表面年龄或根本得不到Re-Os等时线,还有时同一矿床的不同类型矿石给出不同的Re-Os等时线表面年龄。文章介绍了能够解释上述现象的理论模型。模型预测对与基性-超基性岩共生的Cu-Ni硫化物矿床,除一些特殊情况...
青矿山Ni-Cu-PGE矿床位于四川会理县小关河地区,是峨眉山大火成岩省中典型含铂岩浆硫化物矿床之一。本文对该矿床开展了Re-Os同位素组成的分析研究。分析结果表明,不同类型岩矿石的初始Os同位素组成具有明显的不均一性,主要区分出三种不同Os同位素组成的岩矿石类型:不含硫化物的橄辉岩具低γOs,变化范围从15.3到40.3;致密块状和浸染状硫化物矿石相近,γOs值在260左右;海绵陨铁状矿石具有最...

以Y型分子筛为载体，采用液相离子交换法制备Ni-Y分子筛吸附剂。采用电感耦合等离子体发射光谱（ICP）、低温液氮吸附法、X射线衍射（XRD）等手段对Ni-Y分子筛进行表征，使用静态吸附方法考察吸附条件对分子筛吸附燃料油中二苯并噻吩性能的影响，并使用Langmuir-Freundlich（L-F）方程对分子筛的吸附等温线进行拟合。结果表明，Ni2+离子的改性对分子筛的孔道结构影响不显著。吸附过程中，...
稀有气体同位素在示踪成矿作用流体来源方面具有独特优势。本文应用熔融质谱法测定了金川Cu-Ni-PGE硫化物矿床23个硅酸盐矿物和金属硫化物单矿物的He、Ne和Ar丰度和同位素组成。结果表明,硅酸盐矿物的3He/4He比值(0.239Ra)略低于硫化物(平均0.456Ra),且从橄榄石(平均0.291Ra)、斜方辉石(0.215Ra)到单斜辉石(0.174Ra)逐渐降低,20Ne/22Ne-21Ne...
采用ICP-MS分析方法对冷水箐铜镍硫化物矿床矿石的PGE和Re-Os同位素地球化学研究表明,矿石的∑PGE较低,其值变化在7.91×10-9~56.9×10-9之间。矿石的Cu/Pd比值 (9460~318040) 远大于原始地幔的Cu/Pd比值,表明其原始岩浆在早期结晶过程中已经历了硫化物的熔离。矿石的Pd/Ir比值 (2.57~112)变化较小,指示其大多数矿石属于岩浆型。(187Os/18...
