Abstract

Abstract

Qulong porphyry copper (molybdenum) deposit, which is located in the arc-basin transform place between the magma arc of eastern Gangdise and Riduo basin, controlled by basin-controlled, rock-controlled structure in basin edge, and formed in instantaneous transition environment of transform from convergent to extension, is the most potential superlarge deposit in ore-finding and its finding is the important breakthrough in the exploration process of porphyry deposit in eastern belt of Gangdise Mountain. The ore fluid of Qulong porphyry copper (molybdenum) deposit is composed of saturation and supersaturation brine-steam boiling fluids; its distribution characteristics of wall rock alteration include centering by porphyry, surfacing, and annular zone; it has undergone mineralization of 3 periods including 5 phases. It is found that the copper mineralization correlates with anhydrition and sericitization. This paper also probes into some key science issues which call for further studies and attention.
