Abstract：The Garzê-Litang fault zone in Sichuan is one of the important metallogenic regions (zones) on the western Sichuan Plateau. The regional stream sediment survey and early-stage checks of anomalies have revealed rock gold occurrences with larger ore prospects at three gold anomaly sites with high gold concentrations, namely, Ajialongwa, Xionglongxi and Malong. In order to further find out ore information contained in the regional geochemical data, gold anomalies in the stream sediments were taken as the unit in the research work at the late stage and reevaluated in combination of new progress and knowledge in regional mineral prospecting; geochemical statistics and mineralization information prediction were made and target areas were screened with sampling grids as the unit; and a stream-soil-rock geochemical model for mineral prospecting was preliminarily constructed with the Ajialongwa gold deposit (including its surroundings) as the key target of research and ore deposit prediction was conducted. Through checks of the ore district by small amount of drilling, significant mineral prospecting results were obtained. Then after checking part of target areas in the surrounding areas, the Zhaiwulongwa and Adalong rock gold occurrences with larger ore prospects were found at places with weak dispersion flow anomalies. Thus the mineral spaces have been expanded.
