稀矿山式铁铜矿床与奥林匹克坝式铜多金属矿床的对比研究

COMPARISON STUDY FOR THE IRONCOPPER DEPOSITS OF XIKUANGXHAN TYPE AND THE COPPER POLYMETALLIC DEPOSITS OF OLYMPIC DAM TYPE

东川稀矿山式铁铜矿床与奥林匹克坝式铜、铀、金、稀土矿床对比研究表明，有其相似的地质构造背景和某些相近的成矿特征，但在某些成矿条件和矿化特征上又存在较大的差异。因此，在我国某些地质构造环境有利，稀矿山式铜多金属矿发育的地区，提出寻找类似奥林匹克坝式超大型铜多金属矿床，同时也应该注意稀矿山式铁铜矿床的成矿特征和评价标志。

The comparison study between the ironcopper deposits of Xikuangshan type in Dongchuan and the copperuraninmgoldrare earths deposits of Olympic Dam type shows that similar geological and structural backgrounds and some approximate metallogenic features exist in both types,though big differences are also displayed in some metallogenic conditions and mineralization characteristics.It is thus suggested that possibility exists for exploring superlarge copper polymetallic deposits similar to the Olympic Dam type in the regions with preferential geological and structural environment and well developement of copper polymetallic deposits of Xikuangshan type,and meanwhile,special attention be paid to the metallogenic features and evaluation indications of the ironcopper deposits of Xikuangshan type.
