摘要
在深入细致的野外地质工作基础上,参考了大量的锡石标型特征资料,根据锡石不同标型特征与其结晶时的物理、化学条件密切相关的特点,对云南昌宁薅坝地锡矿床锡石的晶体形态、物理性质及化学成分进行了综合研究。结果表明,昌宁薅坝地锡矿锡石属锡石石英岩型,且不同成矿阶段的锡石具有各自的晶体标型特征。其锡石矿床的成因类型为高、中温热液型。该工作为在该地扩大锡石矿床的地质找矿及工业评价,提供了重要的科学依据。
Based on the field geological survey, consulted much feature data of cassiterite typomorphic, according to the close relations between the different cassiterite typomorphic and physical-chemical conditions with crystal circumstance, the morphology physical property and chemical constituents of Changning cassiterite were comprehensively studied. The result shows that Changning cassiterite belongs to cassiterite- quartzite type, and different mineralization stage corresponding to crystal typomorphic feature of their own. The origin classification of cassiterite deposit is believed to be the meso- high hydrothermal type. This research result may contribute to providing scientific gist for enlarging geological mineral exploration and industrial evaluation.
