| 中文摘要:大理—元江—金平镁铁质、超镁铁质岩带南东段的金平地区基性—超基性岩带可进一步划分为三个亚带。白马寨―新安里超基性岩亚带、牛栏冲—蒋家坪基性-超基性亚带内基性-超基性岩岩浆分异程度高、铜镍矿化强烈, 成岩、成矿具多阶段、多期次活动特点。区内铜镍矿床典型的成矿作用方式有熔离—侵位——贯入式、侵位—熔离式铜镍矿等类型。白马寨—新安里、牛栏冲—蒋家坪等地段, 是金平地区超镁铁质岩浆侵入活动和铜镍矿成矿作用的中心区, 也是进一步地质找矿的重要目标区。 |

| Abstract:The Jinping basic-ultrabasic rock belt in the southeastern part of the Dali-Yuanjiang-Jinping mafic and ultramafic rock belt can be further divided into three sublets. The Baimazhai-Xin’anli ultrabasic rock subbelt and the Niulanchong-Jiangjiaping basic-ultrabasic rock subbelt are characterized by high degree of basic-ultrabasic magmatic differentiation, intense copper and nickel mineralization, and multi-stage and multi-phase rock-forming and ore-forming activities. Typical ore-forming activities of copper-nickel deposits in the study area include such types as liquation-emplacement-injection type and emplacement-liquation type. Baimazhai-Xin’anli district and Niulanchong-Jiangjiaping district constitute the central places of ultramafic magmatic intrusion and copper-nickel mineralization in Jinping area, and are also important targets in further geological and ore-prospecting work. |
