The hydrothermal metasomatites of Agarak ore field

The pre-ore propylate and near-ore metasomatites of Agarak ore field and copper-molybdenum deposit have been examined. The connections of biotite and epidote-chloriticfacies are spread along the belt which has 10km extension from North to South. The changes accompanying the sulfide formations are presented with similar quartz-sericite rocks. The quartz-sericitemetasomatites' sericite accompanying the quartz-molybdenum and quartz-chalcopyrite stages is presented with AL-ilites (Al^IV - 0,40-0,44 resolution unit, Al^VI - 1,69-1,72 resolution unit), with a low degree of hydration: about 4,5 mass percent. The fengite component is up to 0,24 and the iron component is up to 0,05. Occasionally it is presented with AL-hydro-sheen, with the same correlation of octahedric and tetrahedric AL. The sheens of quartz-sericitemetasomatite accompanying the quartz-pyrite stage are presented with illites (Al^IV – 0,54 – 0,67 resolution unit, Al^VI– 1,21- 1,50). The fengite component is 0,42-0,80, the iron coefficient is 0,06-0,15, and the hydration degree is 4,5 mass percent more which is typical to hydro-sheen argillite changes
