沂水县炉山白云岩矿床地质特征及找矿标志

Geological Characteristics and Prospecting Indications of Lushan Dolomite Deposit in Yishui County

炉山矿区白云岩矿是以白云石为主的碳酸盐岩,是碳酸钙和碳酸镁的复盐岩石。本文通过分析成矿地质背景,在总结矿床地质特征的基础上,提出炉山白云岩矿床的成因类型属于海相沉积型,明确了三山子组层状白云岩出露地段是直接找矿标志,对鲁南地区找矿具有一定的指导作用。

The dolomite of Lushan ore area is carbonate that composed by dolomite, It is the composite salt rock of calcium carbonate and magnesium carbonate. In this article, through analysis ofmetallogenic geological background and summarization of geological characteristics of the deposit, we put forward the genesis of Lushan dolomite deposit belongs to marine sedimentation. It is clear that the strata distribution or exposed area of Sanshanzi Formation layered dolomite is the direct prospecting indication. The result is an instruction to prospect mineral resources in southern of Shandong province.
