江西朝阳磷矿外围找矿靶区优选

THE OPTIMIZATION OF PROSPECTING TARGETS IN THE PERIPHERY OF THE CHAOYANG PHOSPHORITE DEPOSIT IN JIANGXI PROVINCE

磷矿石是化肥、农药的重要原料之一,近年来国际价格大幅上涨,寻找磷矿石矿产资源显得尤为重要和迫切。江西朝阳磷矿是华东地区最大磷矿床,从1∶20万水系沉积物测量异常入手,综合分析评价了该矿外围化探异常找矿价值,指出朝阳磷矿外围找矿潜力很大,并优选出吴村和五都两个找磷靶区,希望有助于在朝阳磷矿外围寻找磷矿石矿产资源。

Since a year ago, the international rice price has been rising continuously. As one of the important materials of chemical fertilizers and pesticides, the phosphorite price has also been going up. Therefore, the prospecting for phosphorite seems to be very important and urgent. The Chaoyang phosphorite deposit is the largest phosphorite deposit in East China. Starting with the 1：200000 geochemical anomalies from the drainage sediment survey, this paper analyzes and evaluates synthetically the ore-prospecting value of the geochemical anomalies in the periphery of the Chaoyang phosphorite deposit in Jiangxi Province and, on such a basis, points out that the potential is very large. The phosphate prospecting targets in Wuchun and Wudu are optimized in the hope that the work is helpful to the prospecting for phosphorite resources in the peripheral areas.
