摘要:

排山楼金矿位于华北地台北缘,为受控于韧性剪切带的大型金矿床。该矿床成因与韧性剪切带密切相关,矿区成矿地质条件优越,具有很好的找矿潜力。通过总结排山楼金矿地质特征及其主要控矿因素,认为区内韧性剪切带为控岩(控矿)构造,控制着赋矿糜棱岩和金矿体的空间展布,向矿区深部赋矿岩石变薄,找矿空间变小。通过分析T4矿体的品位和厚度分布规律发现,矿体厚度及品位分布规律在空间上表现出高度一致性,根据金品位等值线图判断矿体向南西侧伏。研究认为T4矿体在南西深部其厚度及品位降低趋势明显,向深部工业价值不大,应重点加强对其他韧性剪切带找矿潜力的研究。

Abstract:

The Paishanlou gold deposit is located in the gold province of northern margin of North China Craton,which is the third largest gold province in China.The deposit is mainly hosted in metamorphic rocks of the Jianping Group of Archean and it is structurally controlled by two sets of ductile shear zones.Both the Paishanlou gold deposit in Liaoning Province and Hetai gold deposit in Guangdong Province were firstly been confirmed as ductile shear zone type gold deposits in China.The main orebody T4 in the mining area is controlled by the northeast trending ductile shear zone,and the host rocks are the biotite-plagioclase mylonite and felsic mylonite from Late Archean Jianping Group.The orebody lies in the most strongly deformed rocks in the ductile shear zone,and its hanging wall is dolomitic mylonite.Previous studies have shown that dolomitic mylonite plays a role as a geochemical barrier in the mineralizing process.The Yanshanian granite intruded into the ore-bearing Jianping Group.In this study,by summarizing the geological characteristics and main ore-controlling factors of the Paishanlou gold deposit,it is believed that the ductile shear zone in the area is a rock-controlling and ore-controlling structure,which controls the spatial distribution of the ore-bearing mylonite and gold ore bodies.Granite intrusion causes thinning of ore-bearing rocks which reduced prospecting space.The grade and thickness data of the ore-body T4 were collected in this study.By using the Surfer software to compile the grade and thickness contour maps,the distribution characteristics of the grade and thickness of the ore-body T4 were analyzed.It is considered that the grade and thickness of the ore-body T4 from the east end near the surface to the deep end of the west end can be divided into three obvious gradient zones,and the grade and thickness gradually decrease.The thickness and grade of the orebody shows spatially high consistency.According to the gold grade contour map,we judge that the orebody is leaning to the south and west,with a side leaning angle of 53°.It indicates that the thickness and grade of the orebody T4 in the southwest of the deep have a significant decrease.Therefore,there is no great potential to find economically important orebody in the southwest of the deep.It’s proposed to analyze and research the prospecting potential of other ductile shear zones in the mining area.

Key words: ductile shear zone, ore-forming geological conditions, ore-controlling factors, enrichment regularities of Au element, prospecting potential of deep area, Paishanlou gold deposit, Liaoning Province
