江西省德兴市某金矿调查评价区找矿标志及远景找矿方向

Prospecting criteria and prospective prospecting direction of a gold deposit survey and evaluation area in Dexing City,Jiangxi Province

江西省德兴市某金矿调查评价区位于东乡—德兴铜金多金属矿整装勘查区内,亦处于乐华—德兴金铜多金属成矿带内。本调查评价区与金山金矿田的基本的成矿要素与控矿要素基本相类似。金矿调查评价区外围是德兴富家坞斑岩铜金矿床,本区内金矿体的形成有晚期岩浆热液的改造,这对本区内金矿体的形成创造了更有利的条件,因此我们推测在两种矿床深部的结合部位,存在较好的铜、金复合矿体,所以在这些有利的成矿条件下,将值得进行进一步的深部找矿探索。金矿调查评价区西北部的化探Au、As组合异常并未封闭,其长轴方向与金坑韧性剪切带的走向延伸吻合一致,故沿金坑韧性剪切北东或南西的走向是寻找金矿的有利地段。

The survey and evaluation area of a gold mine in Dexing City,Jiangxi Province is located in the Dongxiang Dexing copper gold polymetallic ore exploration area,as well as in the Lehua Dexing gold copper polymetallic metallogenic belt.The basic metallogenic elements and ore controlling elements of the investigated and evaluated area are basically similar to those of the Jinshan gold field.The surrounding area of the gold deposit survey and evaluation area is the Dexing Fujiawu porphyry copper gold deposit.The formation of the gold ore body in this area has been transformed by late magmatic hydrothermal solution,which creates more favorable conditions for the formation of the gold ore body in this area.Therefore,we speculate that there may be a better copper gold composite ore body at the deep junction of the two types of deposits.Therefore,under these favorable metallogenic conditions,it will be worth further exploration in depth.The geochemical Au and As assemblage anomaly in the northwest of the gold deposit investigation and evaluation area is not closed,and its long axis direction is consistent with the strike extension of the Jinkeng ductile shear zone,so the strike along the northeast or southwest of the Jinkeng ductile shear zone is a favorable area for searching for gold deposits.
