安徽萧县马山头水泥用石灰岩矿矿床地质特征及矿床成因

Geological characteristics and genesis of the Mashantou cement limestone deposit in Xiaoxian, Anhui

为了更好地开发利用萧县地区水泥用石灰岩矿资源,本文对马山头水泥用石灰岩矿矿床地质特征和矿床成因进行了分析。研究表明:矿床赋矿层位主要为寒武系中统张夏组,次为寒武系上统崮山组;矿体出露地表,构造简单,总体呈单斜产出;矿体整体厚度变化较稳定;有用组分CaO含量、主要有害组分MgO含量随倾向和走向变化稳定。该水泥用石灰岩矿为浅海-滨海相碳酸盐岩型层状沉积矿床。

In order to better exploit and utilize the limestone resources for producing cement in the Xiao County area,the geological characteristics and genesis of the Mashantou limestone deposit are analyzed in this paper,indicating that the Zhangxia Formation of the Middle Cambrian prevails over the Gushan Formation of the Upper Cambrian in ore hosting.The ore bodies outcrop and vary stably in thickness,showing a simple structure of monocline.The useful content of CaO and the main harmful content of MgO change as the ore bodies trend and dip.The deposit is believed to be a littoral-neritic facies carbonate rock-type stratified deposit.
