| 英文摘要 | The Ashele volcanogenic massive sulfide ( VMS) deposit is the largest and most representative VMS Cu-Zn deposit in China, but its structural model is still lacking of systematic summary. In this paper, field investigations, excavation pits, drill -core sampling are carried out on the basis of previous studies. Based on a large number of boreholes and profiles observed, the Ashele deposit was dissected. The results show that: (1) There are various types of ore in Ashele deposit, mainly including massive ore, banded ore, stratiform ore, breccia ore, disseminated ore, and stockwork ore. Massive and stratiform ore belong to sedimentary facies orebodies, while stockwork, breccia ore and part of disseminated ore belong to channel facies orebodies. (2) The deposit I contains three exhalation systems, and each of them consists of sedimentary and channel facies. The orebody 1-2 located to the north of No. 13 prospecting line is mainly a massive orebody of sedimentary facies, and the upper part of the orebody has low copper and zinc contents in the stockwork mineralized alteration zone, which is cut through by the later emplaced dacite porphyry. The main orebody I-1 is jointly supplied by two larger channels. (3) The Ashele deposit has multi -stage and superimposed ore -forming characteristics, with late mineralization metasomatism early orebody, and the copper-zinc ore bed at the top of the deposit is formed by enrichment and metasomatism in the late stage. The alteration zoning of the channel is obvious, with silicification zone and sericite chloritization zone in the center and sericite zone on both sides. The vein orebody of the channel phase also shows vertical variation characteristics, from the deep to the stratiform orebody, there are sparse disseminated micro -vein zone, sparse disseminated fine vein zone, medium disseminated coarse vein zone, dense disseminated pyrite vein, and massive pyrite. A barite orebody and hematitic jasper are developed in the lateral distal part of the deposit. On this basis, we construct the structural model of the Ashele Cu-Zn deposit, and discuss the metallogenic evolution model of the Ashele deposit. It is pointed out that the formation of the deposit has gone through a long evolutionary history, including ( multi -period and multi -stage) exhalation sedimentation period, metamorphic and hydrothermal superposition period, shear deformation period and supergene oxidation period. After the formation of the deposit, it was also transformed by various geological processes such as greenschist facies metamorphism. |
