太行山中段冶镁白云岩的发育特征及勘查类型

On the Development Characteristics and Exploration Type of Smelting Magnesium Dolomite in Mid-Taihang Mountain

叙述了华北优质冶镁白云岩的地质特征,勘查结果表明:该地区的白云岩与其围岩界线易于分辨,夹石亦为白云石,品位较低。矿体内部结构简单、厚度稳定、构造相对简单、岩浆岩不发育等方面,确定该区矿体勘查类型确定为Ⅰ类。

This paper describes the geological characteristics of high quality smelting magnesium dolomite in north China, and the exploration results showed that it is easy to distinguish the boundary line between dolomite and its surrounding rock in this region, horse-stone is also dolomite, and its grade is low, internal structure of ore body is simple, its thickness is stable, structure is relatively simple, magmatic rocks is not development, etc., and then determines the exploration type of orebody is ClassⅠ.
