Abstract:
The geochemical characteristics of Longgouhe-Xianhuashan area is studied on the basis of the 1:50 000 stream sediment survey. With large amounts of regional geochemical data, the author carries out a mathematical analysis for 11 elements by variation coefficient, concentration quantile and anomaly characteristics. It is found that Au, Ag, Mo, As and Sb constitute the major ore-forming elements. Based on the anomaly distribution and metallogenic characteristics, two prospective areas for mineralization are optimized. With verification by exploration and surface work, two gold mineralization bodies are discovered.
