A comparative study of the effects of natural heavy mineral prospecting and regional geochemical exploration for gold, tungsten and molybdenum deposits in Jixian County area, Tianjin

Based on the natural heavy mineral and geochemical research for the project of " Mineral Resources Potential Evaluation of Tianjin" in combination with the distribution characteristics of mineral resources in Jixian County area, the authors made a comparative study of the regional prospecting effects for gold, tungsten and molybdenum deposits in Jixian County area by 1∶200000 natural heavy mineral prospecting and 1∶50000 stream sediment survey, investigated the anomaly distribution characteristics, and discovered new prospecting information. The results show that anomalies delineated by these two methods can directly indicate the ore potential of the corresponding geological bodies. The natural heavy mineral anomaly and the regional geochemical anomaly are fairly consistent with each other for specific mineral assemblage, suggesting that these two kinds of anomalies can both play the guiding role in mineral exploration.
