The characteristics of natural heavy mineral anomalies in Sichuan Province and their response to metallogenic potential

In this paper, through the systematic collation and statistic analysis of the natural heavy minerals in Sichuan Province and by using the natural heavy mineral survey data of Sichuan Province (1∶200000) as well as the Native Heavy Mineral Data Bank System (ZSAPS2.0), the authors carried out natural heavy mineral anomaly delineation and anomaly division in Sichuan Province. In combination with the information on mineral resources potential evaluation, the authors hold that natural heavy mineral anomalies can play a certain indication role in ore prognosis, some anomalies can well indicate metallogenic potential, and the natural heavy mineral anomalies delineated can serve as one of the integrated information for ore-prospecting deployment in the whole province and can provide guiding information for ore prognosis at the provincial level.
