福建尤溪十字隔水泥用灰岩矿床地质特征及成因初探

Geological Characteristics and Genesis of Limestone Deposit for Cement Production in Shizige Arer of Youxi, Fujian

十字隔水泥用灰岩矿位于闽西南拗陷带与闽东火山断拗带两大地质构造单元接触带的东侧,矿区圈定水泥用灰岩矿体两个,矿体形态为层状,赋存于早二叠世栖霞组中,其顶、底部受F1、F0滑脱构造控制。根据矿床成矿地质背景和矿床地质特征,认为该矿床是受地层、构造、侵入岩等多因素控制的浅海相碳酸岩沉积矿床。

The Limestone deposit for cement production in Shizige arer is located on the east side of the contact zone between the southwestern Fujian depression zone and the eastern Fujian volcanic fault zone,The mining area delineated two limestone ore bodies,The ore body is stratiform,They occur in the Qixia Formation of the Early Permian,Its top and bottom are controlled by F1 and F0 slipping structures.According to the metallogenic geological background and geological characteristics of the deposit,It is considered that the deposit is a shallow-sea carbonate sedimentary deposit controlled by strata, structure and intrusive rocks.
