| 摘 要： | 老湾金成矿带是变质碎屑岩型金银成矿带之一,在该带发现过上上河和老湾大型金矿床.经对区域1:20万地球化学资料的重新认识,发现沿该带北侧也具有较好的金(银)异常显示,通过1:2.5万水系沉积物测量和1:1万化探详查,将其分解定位,尔后把已知矿(化)点与物化探异常结合起来,在对已知找矿信息综合研究和筛选评序的基础上,确定歇马岭为重点找矿靶区,通过小范围找矿靶区定位分析和工程验证,取得了找矿新进展.

| Abstract: | The gold-silver ore-forming belt in Laowan is one of the gold-silver ore belts of metamorphic clastic rocks.Two large gold deposits were discovered in the Shangshanghe and Laowan area.Later,based on the new researches on the 1:200 000 geochemical data obtained from Laowan,the authors found that gold anomalies obviously exist along the northern part of the belt.Then,through the 1:25 000 survey of hydrographic sediments and the detailed 1:10 000 geochemical exploration, combined with the known geochemical and geophysical anomalies,the authors discovered that Xiemaling is the key target area for ore prospecting.This conclusion is based on the comprehensive study of known information of the mine and the selection of the goals.The local locating analysis and engineering verification of the ore-prospecting target has made new advances in ore-prospecting work. |
