沉积变质矿床中侵入岩脉控矿规律及深层探矿

Influence of intrusive vein on mineralization state of parametamorphic ore deposit and ore search in deep strata

分析了6矿组矿体西部侵入岩脉的岩石结构、地质特征、化学成分、形成机理及其与围岩的交代、置换、充填覆盖状况。根据该区域混合伟晶岩化交代作用纵向减弱的规律,指导布置深层位的探矿工程,查明盲矿体的规模、产状及空间位置,认为其符合工业经济开采价值。

The intrusive vein in the western side of No. 6 parametamorphic ore body is analyzed in respects of its structure, geological properties, chemical composition, formation causes, and relation with wallrock （rnetasomasis, displacement, filling, covering etc）. According to the regularity that the metasomasis extent of mixed pegmatite becomes weaker along longitudinal direction in this zone, the ore search work in deep strata is arranged. Thus the size, occurrence and space location of blind orebody can be forecast.
