Abstract��
Lode 28 is the largest gold-bearing quartz vein in Haigou gold deposit��and the lode itself contains more than 30t of gold�� Geochemical study shows that 12 trace elements related gold mineralization can be divided into 5 metallogenic factors ( element assemblages) �� The high values of F1��F2 and F4 together indicate overlapped of multiple stages of gold mineralization��revealing high potential of gold mineralization at depth; the single high value of F4 represents the root of an existing ore body while high values of F3 and F4 show the intervals of barren sectors in the lode�� Comprehensive geochemical studies show the high prospection potential below the 14th level and between lines 39-71�� It is also prospective to look for blind ore-bodies between lines 15-29 and below the 10th level�� |
