邹城市后山庄熔剂用灰岩矿矿床地质特征及层序地层划分

Geological Characteristics and Sequence Stratigraphic Division of Houshanzhuang Flux Limestone Deposit in Zoucheng City

后山庄熔剂用灰岩矿位于菏泽—兖州潜断隆(Ⅳ)兖州潜凸起(Ⅴ)的东南部,矿床赋存于长清群张夏组中。矿床内分3个矿段9个矿层,呈层状、似层状产出。矿石类型主要为鲕粒灰岩和藻灰岩。矿床属于浅海相碳酸盐岩含矿沉积建造,赋矿层位张夏组划分为两个层序,属包含海侵体系域和高水位体系域的二元结构。找矿标志明显,找矿前景良好。

Houshanzhuang flux limestone deposit is located in southeastern part of Yanzhou projec- tion Heze-Yanzhou uplift, and the deposit occurs in Zhangxia formation of Changqing group. Three graphite ore bodies developed in this deposit with layered and stratiform-like types. Main types of ores are oolitic limestone and algal limestone. The deposit is a neritic carbonate sedimentary forma- tion containing ore. Zhangxia formation is divided into two m sequences, which is a dual structure comprising TST and HST. The prospecting symbol is obvious and the exploration prospect is good.
