| 摘 要： | 金矿床中黄铁矿的化学元素、晶体形态、粒度等标型特征与其形成的物理化学环境及介质条件密切相关.通过对陕川丁家林-太阳坪金矿区主要载金矿物黄铁矿在韧性剪切变形-构造分异热液期与脆性剪切变形-构造分异热液期化学元素含量对比,以及黄铁矿形态、粒度分析,研究黄铁矿与金矿物关系.丁家林-太阳坪金矿黄铁矿形态以{100}、{210}单晶及{100} {210}聚晶为其标型.黄铁矿在空间分布特征来看,深部成矿的可能性不大.应沿丁家林-太阳坪脆-韧性剪切带寻找金矿.

| Abstract: | Typomorphic characteristics of pyrites in Au deposits, such as chemical elements, pyroelectricity and crystal form are closely related to the physio-chemical conditions under which they were formed. This paper deals with relation of pyrite to Au minerals in Dingjialin-Taiyangping Au deposit according to the chemical analysis of elements in gold -bearing pyrites formed in the ductile deformation-tectonic differentiation hydrothermal and the brittle deformation-tectonic differentiation hydrothermal stage respectively and their morphologes and grain sizes. Single crystals with {100}, {210} and polycrystals with {100}+{210} are typomorphology of pyrite in Dingjialin-Taiyangping Au deposit. The relation shows that ore formation is unlite to depth thus further exploration should be along Dingjialin-Taiyangping britlle-ductile shear zone. |
