摘要
黑水地区锰矿床主要赋存于下三叠统菠茨沟组地层中,受构造控制。矿石矿物主要有硬锰矿、软锰矿、褐锰矿、菱锰矿、钙菱锰矿等。脉石矿物主要有磁铁矿、针铁矿、黄铁矿等。主成矿元素锰的资源量可达特大型以上,属于沉积变质型锰矿床。该区及外围均具有很大的找矿潜力。
Mn deposits in Heishui, Sichuan are confined to the Lower Triassic Bocigou Formation and controlled by structure. Ore minerals are composed of psilomelane, pyrolusite, braunite, rhodochrosite and manganocalcite and gangue minerals are composed of magnetite,goethite and pyrite and so on. The deposit belongs to sedimentary metamorphic type with giant reserves. The Heishui area is very perspective for Mn resources.
