| 中文摘要: |
| 智利贝多尔嘎拉尼帕铜金矿区地处智利斑岩型铜矿带的西侧,矿区地表矿体严格受到近南北向及北东向构造控制,同时与隐伏岩体(花岗闪长斑岩?)具有密切的空间关系。地表已经发现的众多小型矿床主要为浅成低温热液型铜矿类型,但是该区的外围又产出一些曼陀型铜矿(或IOCG型矿床)。从成矿地质条件综合分析,该区深部赋存曼陀型及斑岩型铜矿的可能性很大,尤其是曼陀型铜矿的勘查,是找矿突破的主要方向。矿体中黄铜矿、斑铜矿等铜的硫化物发育,对于激电测深有较好的适用条件,通过预查阶段应用,在该区找矿评价中取得了良好的效果。 |
| 英文摘要: |
| The Peteroca Lanipa copper gold deposit is located on the western side of the porphyry copper belt in Chile, the copper orebody is strictly controlled by near NS-trending and NE-trending structures. And the copper mineralization is closely related to the concealed magmatic intrusive (probably granite diorite porphyry)spatially. A large number of small sized copper deposit found on the surface mainly belong to the hypabyssal low temperature hydrothermal copper deposit type, but in the periphery area of the deposit, some Mandolin type (or IOCG type) copper deposit was found. Based on the comprehensive analysis of metallogenic geologic conditions, there is great possibility to discover the Mandolin type and porphyry type copper deposits at the depth of the deposit area, especially the exploration for the Mandolin type copper deposit is the main of prospecting direction in this region. The copper-gold orebody enriches chalcopyrite and bornite, sulphides which is very suitable for the application of IP sounding method. The practical application by IP survey in the prospecting stage has achieved sounding exploration effect in the deposit area. |
