摘　　要：松桃石塘锰矿床是上世纪60年代中期贵州省地矿局103地质队发现,并在本世纪初评价提交的小型锰矿床。锰矿产于南华系下统大塘坡组第一段(含锰岩系)下部黑色碳质页岩中,矿体呈层状、似层状倾斜产出,矿体走向长700余米,倾向斜深800 m,矿体厚0. 221. 30 m,平均0. 86 m。本次通过对含锰岩系、锰矿体厚度等变化规律的分析研究,运用南华纪锰矿裂谷盆地古天然气渗漏成矿理论和深部隐伏矿找矿预测模型进行类比分析,圈定了石塘IV级地堑盆地的空间分布范围,该盆地呈北东65°左右方向展布,长3 600 m,宽800 1 400 m,在盆地北东东方向尚具有较大找矿潜力。The Songtao Shitang manganese deposit was discovered by the 103 Geological Team of the Guizhou Bureau of Geology and Mineral in the mid-1960s and was evaluated as small manganese deposit at the beginning of this century.Manganese ore occurred in the black carbonaceous shale in the lower part of the first section of the Datangpo formation of the South China System(manganese-bearing rock series)bedded and stratoid,the ore body is more than 700 meters long.The depth of the slope is 800 meters,and the thickness of the ore body is 0.22 to 1.30 meters,with an average of 0.86 meters.Based on the analysis of the variation law of manganese-bearing rock series and manganese ore body thickness,the analogy analysis of the ancient gas leakage ore-forming theory and the deep concealed ore prospecting model manganese ore rift basin was used to delineate the Shitang IV in the Nanhua period.The spatial distribution of the gradual mantle basin,which is distributed in the direction of about 65°northeast,is 3 600 m long and 800-1400 m wide,and has a large potential for prospecting in the northeast direction of the basin.
