| [摘 要] 河南省信阳市光山县陈岗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，1:5万区域矿产远景调查在该区圈出了以钼为主的水系沉积物综合异常。本文叙述了1:5万综合异常的查证结果：1:1万土壤地球化学测量圈出的钼异常强度高、面积大、浓集中心明显，实施的槽探和钻探工程验证表明，在探槽中钼均呈弱矿化，钻探发现四层钼矿体，其中第一、二、四层矿体厚度、品位均达到工业指标要求，第三层矿体达到边界品位，取得了较好找矿成果。 |

| Abstract: The Chengang area is located in the nearly north-south-trending molybdenum anomaly zone from Qian’echong of Guangshan county to Shangqipan of Xinxian county, which shows a good molybdenum ore prospecting potential. Molybdenum-dominant anomalies in drainage sediments were delineated by a survey of regional mineral resource at a scale of 1:50,000. This paper describes the inspection results of the multiple anomalies in the Chengang area. The molybdenum anomaly discovered by the geochemical soil survey at a scale of 1:10,000 has high intensity, a large area and clear concentration centers. Examinations in trenches show very low molybdenum mineralization. In drilling holes, 4 layers of molybdenum ore bodies were found, of which the thickness and grade of the 1st, 2nd, and 4th ore bodies meet commercial demand. The grade of the 3rd-layer ore body reaches the cutoff value. These figures imply a fairly good result of ore search effort. |
