摘要
四川黑水徐古锰矿位于日嘎希—瓦钵梁子复背斜西段北翼。铁锰矿赋存于下三叠统菠茨沟组浅海相泥质—碳酸盐类的混合沉积物中,地层、岩性控矿明显。矿体呈层状、似层状产出,沿走向、倾向延伸比较稳定。属沉积变质类型,具有7种找矿标志。
The Xugu Mn deposit in Heishui, Sichuan lies in the northern limb of the Rigaxi - Waboliangzi anticlinorium. Fe - Mn ores are confined to the neritic argillaceous - carbonate formation of the Lower Triassic Bocigou Formation and controlled by the stratum and lithology. The orebodies occur in bedded and stratoid forms and are stable along strike and direction of dip. The deposit is a sedimentary - metamorphosed one. 7 prospecting criteria come into existence.
