摘要
Through the gravity survey (1∶ 25 000) on the low-valued regional gravity anomaly (1∶200 000) in Luanchuan County, southwestern Henan Province, the preliminary low-valued anomaly is subdivided into more than ten low-valued local anomalies with the different sizes. Combining with the geological and mineralization,it is sugguested that nine of these local anomalies reflect the existence of the subsurface granite stocks connecting to the large concealed granite pluton. Accordingly, many potential targets for searching Mo-Pb-Zn deposits are found out. And now, three hidden ore mineralization occurrences have been disclosed by recent exploration projects.
