四川自然重砂异常特征及其成矿潜力响应

在自然重砂数据库系统（ZSAPS2.0）平台下，通过对四川省1∶20万自然重砂测量数据中的全省自然重砂矿物进行整理、统计和分析，开展了四川省自然重砂异常圈定及异常区带划分。结合四川省矿产资源潜力评价工作相关信息认为，自然重砂异常在矿产预测中具有一定的指示作用，部分具有较好的成矿潜力，所划分的自然重砂异常可作为全省开展相应矿种找矿工作部署的综合信息之一，可为省级找矿预测提供指导性信息。

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.
