摘要
梨林头水泥用灰岩矿床赋存于中奥陶统马家沟组第五岩性段,为海相生物沉积型石灰岩矿床,含矿建造是海相沉积.矿石的自然类型可分为致密块状和花斑状矿石两种类型,两者呈互层状、渐变关系,其中以致密块状矿石为最多.矿体平均品位满足Ⅰ级品质量要求,是优质的水泥原料.矿区西部有大面积的奥陶系马家沟组灰岩分布,成矿地质条件良好,具有较好的找矿前景.
Abstract
The Lilitou cement limestone deposit is located in the fifth lithological segment of the Majiagou formation in the Middle Ordovician,and is a marine biogenic sedimentary limestone deposit.The ore bearing formation is marine sedimentary.The natural types of ore can be divided into two types:dense blocky ore and spotted ore,with a layered and gradient relationship between the two,with dense blocky ore being the most common.The average grade of the ore body meets the quality requirements of Grade Ⅰ products,making it a high-quality cement raw material.There is a large area of Ordovician Majiagou formation limestone distribution in the western part of the mining area,with good ore-forming geological conditions and good prospecting prospects.
