| 中文摘要: |
| Amanforom矿区位于加纳西南部塞夫维(Sefwi)金成矿带上,区内第四系红土层发育,覆盖严重,以往工作程度低。根据矿区特点和以往工作情况,确定了地质物化探综合找矿方法,用时一年零两个月发现了Ⅲ号隐伏金矿带,既经济又快速地评价了该矿区。在该矿带的发现过程中,土壤化探和槽探发挥了重要作用,物探则有利于该矿的进一步评价。本文描述了该矿的发现过程,从找矿方案设计到具体实施,再到找矿效果,初步总结了该矿的找矿经验,以期对将来该地区及其他地质条件相似地区的找矿工作有所助益。该矿初步探获金资源量5.13 t,目前已建成矿山投产。 |
| 英文摘要: |
| The Amanforom mining area is located in the Sefwi gold mineralization belt in southwest Ghana, the larterite of Quaternary covering in large area with few bedrock outcrop.According to the characteristics of the mining area and the previous work,we decided to adopt the integrated prospecting method of organic combination of geological-geophysical-geochemical exploration.It took one year and two months to discover the hidden gold deposit Ⅲ,which not only economically but also rapidly evalucated the mining area.Soil geochemical exploration and trough exploration played an important role in the discovery of the deposit,and geophysical exploration is beneficial to the further evaluation of the deposit.This paper focuses on the discovery process of the mine,from the design of prospecting scheme to the concrete implementation,and then to the effect of prospecting,and preliminarily summarizes the prospecting experience of the mine,hoping to be helpful to the prospecting work in this area or other areas with similar geological conditions in the future.The initial gold resourses obtained from the mine are 5.13t,and the mine has been built up at present. |
