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。
河南省信暘市新縣上棋盤地區位于近南北嚮光山韆鵝遲-新縣上棋盤鉬異常帶上，具有較好的鉬礦找礦前景。筆者敘述瞭該區1∶20萬、1∶5萬水繫沉積物測量綜閤特徵，著重探討瞭1∶1萬土壤地毬化學測量異常特徵，利用地質纍積指數對研究區內的土壤地毬化學元素組閤進行評價，經槽探和鑽探工程驗證，髮現7條鉬礦體，取得瞭較好找礦成果。

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 1 ∶ 10000. 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.
