中文摘要:
      松桃大屋锰矿是贵州省地矿局103地质队于上世纪70年代勘查评价的中型锰矿床。锰矿产于南华系大塘坡组第一段黑色岩系底部,矿体呈层状、似层状产出,矿层走向北东约70°,矿体平均厚1.42 m,平均品位18.85%。矿区从北西向南东,含锰岩系、锰矿体从无到有。大屋锰矿床只保留了古天然气渗漏沉积成矿系统中的过渡相和边缘相,中心相应在齐公坡一带,但已被剥蚀殆尽。通过构造古地理恢复分析,推测南华纪大屋地堑盆地长大于14 km、宽约4 km,沿北东70°方向展布。预测盆地北东柳树塘、大坳至孟溪一带还具有发现中-大型规模锰矿床的潜力。
英文摘要:
      Dawu manganese was a middle scale manganese explored and accessed by 103 geological party in 1970s.the manganese deposit occur in the black rock series bottom of the 1st section of Datangpo formation,Nanhua series,the orebody occur bedded and stratoid,the seam strike NE 70°,the average thickness is 1.42 m and the average grade is 18.85%.in the mining area,from NW to SE,the manganese-bearing rock series and manganese orebody developed from nothing.In Dawu manganese deposit,there are only transient phase and marginal facies kept in the ancient natural gas seepage sedimentary metallogenic system,the intermediate phase should in Qigongpo area but be eroded absolutely.By tectono paleogeography recovery study,it’s inferred the length of Dawu graben basin is more than 14 km,the width is about 4 km and distribute along NE 70°.Therefore,it has potential to found middle-large scale manganese deposit in Niushutang, Daao-Mengxi area in NE of the basin.
