| 摘 要： | 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.

| 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． |
