摘要
河南省信阳市新县上棋盘地区位于近南北向光山千鹅冲—新县上棋盘钼异常带上,具有较好的钼矿找矿前景。笔者叙述了该区1∶20万、1∶5万水系沉积物测量综合特征,着重探讨了1∶1万土壤地球化学测量异常特征,利用地质累积指数对研究区内的土壤地球化学元素组合进行评价,经槽探和钻探工程验证,发现7条钼矿体,取得了较好找矿成果。
Shanqipan area is located near the NS-trending molybdenum anomaly zone from Qian＇echong in Guangshan County to Shan- gqipan in Xinxian County. The region has good molybdenum ore prospecting potential. The authors made a comprehensive analysis of the combined features of stream sediment geochemical survey at the scales of 1 ： 200000 and 1 ： 50000, with emphasis placed on the soil geochemical survey at the scale of l ： lO000. An evaluation was also made on the soil geochemical element association by index of geoaccumulation. Trenching and drilling verification led to the discovery of 7 molybdenum orebodies, thus achieving satisfactory ore- prospecting results.
