广西贵港天堂岭水泥配料用砂岩矿地质特征及矿床成因浅析

Metallogenic geological characteristics and genesis of Tiantangling sandstone deposit for cement batching in Guigang,Guangxi Province

贵港天堂岭水泥配料用砂岩矿是广西重要的硅砂基地之一。该矿床产于下泥盆统莲花山组中,赋矿岩性主要为灰白色、紫红色中细粒石英砂岩,属海相沉积型矿床,矿体呈层状产出,产状较稳定,南北长约440m,东西宽约280m,厚度102m~122m。本文在已有研究基础上,通过对矿区地层、构造、矿床地质及成矿地质条件分析,探讨了天堂岭砂岩矿矿床成因。本文对天堂岭水泥配料用砂岩矿矿床及类似矿山开采具有参考价值。

Tiantangling sandstone mine for cement batching is one of the important silica sand bases in Guangxi.The deposit occurs in the Lianhuashan formation of Lower Devonian.The main ore hosting lithology is grayish white and purplish red medium fine-grained quartz sandstone.It belongs to marine sedimentary deposit.The ore body occurs in layers with stable occurrence.The exposed north-south length is about 440m,the East-West width is about 280 m,and the thickness is 102-122 M.On the basis of previous studies,this paper preliminarily analyzes the genesis of tiantangling sandstone deposit through the analysis and discussion of strata,structure,deposit geology and metallogenic geological conditions in the mining area,which is of great significance for the next step work of tiantangling sandstone ore deposit for cement batching and similar mining.
