南仇铁矿地质特征及矿床成因

Geological Characteristics and Deposits Origin of Nanchou Iron Deposit

南仇铁矿床位于鲁西临淄境内,为小型褐铁矿矿床。矿体以层状或似层状为主;矿体规模较小,厚度、品位变化较大;褐铁矿矿石自然类型以致密块状、蜂窝状、粉粒状为主。断裂构造和围岩对成矿、控矿具有重要的作用,矿体以交代作用为主。矿床成因属中低温热液交代充填—风化淋滤型矿床。沿层间及深部均有较好的找矿前景。

Nanchou iron deposit is a small limonitel deposit in Linzi,western of Shandong province.The form of orebody is bedded or stratoid vein.The mass of ore is small size orebody varying in thickness and grade.The main natural type of limonite ore includes massive,honeycomb and pulverulent.The fault structure and wall rock are important mineralization and ore-controling factors.The deposit is a middle-low hydrothermal type related to metasomatic filling-weathering and leaching processes.The interlayer and deep location of the main fault structure have preferable prospect of limonite exploration.
