龙塘矿区的石英砂岩产于下石炭统大塘组旧司段中下部。矿石是机器制造工业铸型用的优质原料,还具有作提炼结晶硅、碳化硅、冶炼硅锰、硅铁等多种用途的广阔前景。可为贵州机器制造工业部门提供丰富的矿石原料。本文拟对该矿床地质特征、工业意义、沉积环境及找矿方向作一介绍。矿区地质在南北长五公里、东西宽四公里的矿区范围内,出露地层主要为下石炭统大塘组及部分摆佐组;矿区北部始有上泥盆统(D_3)高坡场组及下石炭统岩关组
The quartz sandstone of the Longtang mining area is produced in the middle and lower parts of the old section of the Lower Carboniferous Datang Formation. Ore is a high-quality raw material for machine-made industrial molds, and has broad prospects for refining various uses such as crystalline silicon, silicon carbide, smelting silicomanganese and ferrosilicon. Guizhou machinery manufacturing industry can provide rich ore raw materials. This article intends to introduce the geological features, industrial significance, sedimentary environment and prospecting direction of this deposit. In the mining area within five kilometers of the north and south and four kilometers of east-west width, the geological formations of the mining area are mainly the Lower Carboniferous Datang Formation and part of the Zuozuo Formation. In the northern part of the mining area, the Upper Devonian (D_3) Lower Carboniferous rock group
