Geological Characteristics and Evaluation of Development Conditions of the Cement Limestone Deposit in the Peripheral Area of Xiaoge Village,Xuancheng City,Anhui Province,China
摘要
Abstract
This paper investigates a cement-grade limestone deposit in the peripheral area of Xiaoge Village,Xuancheng City,Anhui Province.Based on field geological surveys and a systematic review of previous research,we analyze the geological characteristics of the deposit,including the morphology,scale of the ore bodies,ore quality and mining technical conditions.The genesis of the deposit is preliminarily discussed,and the prospects for its resource development and utilization prospects are evaluated.The results show that the ore body occurs mainly in the Lower Triassic Yinkeng,Helongshan and Nanlinghu Formations,forming a large-scale monoclinal stratiform deposit.The ore maintains consistently high quality and is classified as Class I,with an average CaO content of 51.59%and low contents of harmful components such as MgO(0.98%).The deposit is interpreted as a shallow marine sedimentary-diagenetic carbonate type.Hydrogeologically,it is a karst water-filled deposit dominated by dissolution fractures.The engineering geological conditions are moderate,and potential environmental geological issues are controllable,indicating that the deposit is suitable for open-pit mining.This study provides a reliable geological basis for the scientific planning and sustainable development of cement raw material resources in this region.关键词
