宁夏米钵山电石灰岩矿床地质特征及成因探讨

Geological characteristics and causes discussion on electric limestone ore in miboshan, Ningxia

通过地质调查、采样测试等方法,查明了米钵山电石灰岩矿体特征、矿物成分、结构构造及其成因.结果表明,该矿床赋存于奥陶系下统马家沟组石灰岩地层中,褐红—紫红灰色薄—中厚层状细晶白云岩、白云质灰岩是区内寻找电石灰岩的最主要标志层,为今后该地区查找电石灰岩矿提供了参考依据.

Through the ways of geological investigation and sample test, characteristics of electric limestone ore body, mineral composition and structure, and its causes were found out in Miboshan. The deposit occurs in lower ordovician limestone strata in Majiagou group. Maroons- purple grey, thin or middle thick layer of fine crystal dolomite and dolomitic limestone is main sign layer for searching limestone in the area.
