| 英文摘要: |
| Ashelei massive copper zinc sulfide deposit is a large-sized volcanogenic deposit firstly discovered in Altai area. It occurs in Altai tectonic-metallogenie zone. Its host rocks are dacitie pyroclastic rocks and volcaniclastic-sedimentary rocks of Ashelei group of Middle Devonian. This deposit is intimately related to subvolcanic rocks. This deposit occurs in late stage of volcano-sedimentary cycle or between two volcano-sedimentary cycles. It is controlled by faults and volcanic apparats, and reformed by late-tectogeneses. Besides, these ores are enriched by supergenesis. Altai tectonic-metallogenic zone has geotectionic, geochemical and geophysical conditions for forming Ashelei-type deposits, and has perspectives for looking for the type of deposits. On the basis of studying Ashelei massive sulfide deposit, prospects of ore deposits are indicated in Altai area. |
