| [摘要]皮家寨水系沉积物化探异常位于大别山北坡北淮阳构造带,受控于龟(山)-梅(山)断裂,
综合异常区面积32 km2 ,异常组分复杂,套合性较好,强度高。该异常区属于北淮阳凉亭金成矿带,是老
湾金成矿带的东延部分。为了提升该地区的矿产地质研究程度、总结以前找矿成果、指导以后的找矿工
作,作者对比老湾金矿的成矿模型、并运用韧性剪切带成矿的金矿成矿新理论,从区域成矿背景、地层、
构造等几方面探讨了该金异常区的成矿条件,认为该异常区成矿地质条件优越,深部应具有较大的找矿
潜力,并为该地区以后的矿产勘查工作指明了方向。 |

| Abstract:Geophysical and geochemical surveys have found gold anomalies in drainage sediments in the Pijiazhai area located in the Beihuaiyang tec鄄
tonic belt of the northern Dabie Mountains, which is controlled by the Guishan-Meishan fault. The area of comprehensive anomalies is about 32 km2 ,
characterized by complex compositions, high intensity and good combination. This gold anomaly area belongs to the Liangting gold metallogenic belt in the
Beihuaiyang tectonic belt, as the eastward extension of the Laowan gold metallogenic belt. In order to enhance geological research and summarize the re鄄
sults of previous survey to guide the later prospecting work, we make comparison with the Laowan gold metallogenic model and use the new theory on gold
deposits in ductile shear zones to analyze the conditions of mineral formation in this area, such as the regional metallogenic background, the strata and
structures. We think that this anomaly area has good metallogenic geological conditions and a big potential of prospecting at depth. This work will help
guide the mineral survey of this area in the future. |
