摘要:

宁夏卫宁北山地区是宁夏重要的多金属成矿区带。多年来,大量的地质普查工作发现了30多个金、铜、铁等矿(化)点,但由于工作手段单一、地质构造情况复杂等因素,一直未能有大的找矿突破。以宁夏矿产资源潜力评价项目自然重砂资料研究为基础,将卫宁北山地区的金、铜、铅等单矿物(或组合矿物)重砂异常进行叠加,根据其套合情况,结合地球化学异常、区域成矿地质条件和相关的地质矿产信息,编制了卫宁北山地区自然重砂综合异常图,并对其自然重砂异常特征及其找矿指示意义进行探讨。

Abstract:

Weining’s Beishan area of Ningxia is an important polymetallic metallogenic belt. Over years, a geological survey work has found more than 30 gold, copper, iron occurrences, but no breakthrough due to poor work and complicated geology and structures. This paper, by using heavy minerals survey data of Ningxia Resources Potential Assessment Project, overlaps Beishan’s gold, copper and lead single minerals (or combination), combined with geochemical anomaly, regional geology, compiles Beishan Area heavy minerals anomaly map and discusses their indication for prospecting.

Key words: Ningxia, Weining Beihan, natural heavy minerals, anomaly characteristics, indication of prospecting
