山东省枣庄市侯孟熔剂用白云岩矿地质特征及开发利用前景

Geological Characteristics and Development and Utilization Prospects of Houmeng Dolomite Mine in Zaozhuang City in Shandong Province

摘要:

侯孟熔剂用白云岩矿位于枣庄市台儿庄区张山子镇东南，区内圈定了1个矿体，呈层状产出，矿体赋存于震旦纪土门群石旺庄组地层中，受地层层位控制，产出稳定。矿物成分主要为白云石，矿石结构以泥微晶结构为主，块状构造，矿石自然类型为灰色细晶白云岩。该矿床为滨海泻湖相沉积的层状石灰岩经白云岩化形成的交代型白云岩矿床，矿石主要有用组分含量分别为MgO 19.73%，CaO 30.33%，达到了熔剂用白云岩的工业标准要求,具有良好的开发前景。

Abstract:

Dolomite ore for flux in Houmeng in Zaozhuang city in Shandong province is located in the southeast of Zhangshanzi town in Taierzhuang district of Zaozhuang city. One ore body occurred as stratified type has been delineated in the area. The ore body occurs in Shiwangzhuang formation of Sinian Tumen Group. It is controlled by the stratum and the output is stable. The main mineral composition is dolomite, and the ore structure is dominated by mud microcrystalline structure and massive structure.The natural type of ore is gray finecrystalline dolomite.The deposit is a metasomatic dolomite deposit formed by dolomitization of layered limestone deposited in coastal lagoon facies. The main useful components of the ore are as follows: MgO is 19.73% and CaO is 30.33%. It has reached the industrial standard for flux dolomite, and has a good development prospects.
