在较为详细的野外地质观测和精确的同位素测年的基础上 ,结合前人资料 ,将中甸地区的印支期岛弧斑岩体分为东、西两个斑岩带 ,东斑岩带形成于 2 1 8～ 2 0 3Ma ;西斑岩带形成于 2 4 2 .92～ 2 37.5Ma。喜马拉雅期(5 3.0 2Ma)斑岩叠加于早期的斑岩体之上 ,与斑岩铜矿化关系密切。中甸地区岛弧带内东、西两个斑岩带的斑岩型铜矿找矿远景极大 ,尤以东斑岩带前景最佳 ,普朗斑岩铜矿床远景规模在大型以上。中甸斑岩铜矿将成为我国又一重要的斑岩铜 (多金属 )矿产地
On the basis of more detailed geologic observation and accurate isotope dating, combined with the previous data, the Indosinian island porphyry in Zhongdian area is divided into two porphyry zones in east and west, Formed at 218 ~ 2 0 3Ma; the porphyritic zone formed at 224.292 ~ 237.5Ma. Himalayan (5 3.0 2Ma) porphyry superimposed on the early porphyry and closely related to porphyry copper mineralization. Prospects for prospecting of porphyry copper deposits in the eastern and western porphyry belt of the Zhongdian area arc belt are extremely great, especially in the eastern porphyrite belt. The prospect of the Pulang porphyry copper deposit is large in scale. Zhongdian porphyry copper mine will become another important porphyry copper (polymetallic) mineral deposit in our country
