| 中文摘要: |
| 观山寺绿松石矿床是竹山县具有代表性的绿松石矿床之一,近年来显示良好的找矿潜力,但其地质特征、控矿因素、矿床成因及成矿规律并不明晰,对矿床后续的勘查工作形成了严重阻碍。为此,本文在收集前人资料的基础上,进行了全面的野外地质调查工作和系统的勘查工程布置,并结合必要的室内分析手段,查明了观山寺绿松石矿床的基本特征:含矿岩系为一套含碳的泥质板岩、硅质板岩的岩石组合；矿区北东部寒武系庄子沟组地层中密集发育并与褶皱轴平行的扇形节理和裂隙是绿松石良好的导矿和容矿构造；绿松石矿体的形态为透镜状、脉状、葡萄状和板状,其中以透镜状为主,多顺层产出,常发育于含矿层的层间挤压破碎带中,在空间上呈单体或首尾相接的串珠状、藕节状成群出现。矿石构造主要为结核状、鲕状、镶嵌状,其次为脉状、板状以及薄膜状。本文初步认为观山寺矿床的成因类型为风化淋滤型,其中物质组分来源、构造条件、氧化还原环境、自然地理4个方面的因素控制了矿床的形成,并在此基础上提出了具体的找矿标志,以期对该矿区进一步的找矿工作和类似矿床的勘查部署提供指导和帮助。 |

| The Guanshansi turquoise deposit is one of the representative turquoise deposits in Zhushan County. It has shown good prospecting potential in recent years, but its geological characteristics, ore-controlling factors and ore-forming rules are not clear, which have seriously hindered the subsequent exploration of the deposit. Therefore, on the basis of collecting previous data, this study carried out a comprehensive field geological survey and systematic exploration engineering layout, and combined with the necessary indoor analysis, then found out the basic characteristics of the Guanshansi turquoise deposit:the ore-bearing rock series is a set of carbonaceous argillaceous slate, siliceous slaterock combination; The fan-shaped joints and fractures in the strata of the Cambrian Zhuangzigou Formation in the north of the mining area are closely developed parallel to the fold axis, which are good ore-conducting and ore-holding structures of turquoise. The morphology of turquoise ore bodies is lenticular, vein-like, grape-like and plate-like, among which lenticular is the main form, mostly produced along the layers, often developed in the interlayer extrusion fracture zone of ore-bearing layers, and appeared in groups of monomial or beaded and rose-like bodies connected end to end in space. The ore structure is mainly nodular, oolitic and Mosaic, followed by vein, plate and film. This article points that the formation of Guanshisi ore deposit is due to weathering leaching process, and the formation is influenced by four factors:the source of the material composition, structure condition, redox environment and geological location. Based on these factors, this article puts forward specific methods to find the mine, aiming to offer help and guidance to ore-searching in this region as well as similar ore-searching work. |
