| Abstract: | The polymetallic deposit of Ashele pyrite type is contributed in middle Devonian quartz-andesitic volcanosedimentary series in Altai geosyncline fold system.
The ore is filled in the volcanic vent or round the crater with the major body buried underground. The ore-forming elements are iron, copper, lead, zink. gold, silver, sulfer, barium etc, with the accompanying elements being germanium, gallium, indium, selenium, cadmium bismuth etc.
Morphologically the ore body is complex and branching off in its upper part, but unified in the depth. It is a tubular body tipping east and tilting north.
The vertical zonation is noticed in the ore body from up to down as follows:
1. barite-silicification zone;
2. pyrite-polymetallic zone:
3. pyrite-copper, zink zone; |
