个旧老厂锡矿的“锡石碳酸盐期硫化物迭加型”矿床,目前保有的地质储量占原生锡矿地质储量的3％。对该类型矿床的地质特征及工业利用,长期以来有着争议。该类矿床往往赋存于原生锡矿其它类型矿床之上部,不解决其利用问题,就直接影响下部矿床的勘探和开发。本文以老厂矿田I—4号矿体为例,通过重做坑内地质工作,对矿床的地质特征作了较深入的剖析,指出了锡矿化富集与两期矿化迭加和地层岩性、构造的关系;並对其工业利用作了一定程度的验证。
Gejiu old tin factory “cassiterite sulfide superimposed type” deposits, the current reserves of geological reserves accounted for 3% of the geological reserves of native tin. The geological features and industrial utilization of this type of deposits have long been debated. Such deposits often occur in the upper part of other types of primary tin deposits, and their use problems will not be directly affected the exploration and development of the lower deposits. Taking the orebody I-4 in Laochai Mine as an example, the geologic characteristics of the ore deposit are analyzed in depth through the reworking of the geologic work in the pit. It is pointed out that the tin mineralization enrichment is related to the superimposition of two mineralizations and the stratigraphic rocks Sexual, structural relations; and to a certain extent, its industrial use of verification.
