摘要：
The Prognoz Ag-Pb-Zn deposit contains a number of silver sulfosalt minerals in minor and trace amounts in epithermal quartz-siderite zones hosted by siltstones and sandstones of Triassic age. 'Fahlore' which is a common constituent, contains 0.7 to 51 wt. % Ag. Pyrargyrite, stephanite, owyheeite, diaphorite, freieslebenite, andorite, ramdohrite, gustavite are identified. Considerable Sb-Bi isomorphous substitution was found in the lillianite and andorite homologues. Fluid inclusions in quartz and carbonates consist of two phases and homogenize at 225 to 100 degrees C. The fluid contains 29 to 8 wt. % NaCl+KCl.
