【摘要】：本文以浅成低温热液型金矿为重点研究对象,通过成矿地质体、成矿构造和成矿结构面、成矿作用等方面的研究,结合必要的大比例尺专项地质填图及物化探工作,构建找矿预测模型,开展找矿预测研究,强化成果应用,及时为深部勘查工程布置提供合理化建议,以整装勘查区为单元,编制系列基础图件。东安岩金矿区为伊春—延寿成矿带北部重要的岩金矿区,现已发现7个矿体群,都集中于东安矿区的西矿带,而东矿带因第三系孙吴组覆盖面积较大,但东矿带的成矿地质条件与西矿带相似,与成矿密切的潜火山岩和热液蚀变发育,具有很大的找矿潜力。本次工作主要利用地质、物化探综合手段对该区地质特征、成矿地质条件及矿体的规模、形态、产状和质量情况深入研究,从而提出进一步详查的建议和依据。本文以东安金矿为重点工作区,开展矿床地质特征研究,厘定成矿地质体、成矿构造和成矿结构面,总结成矿作用特征标志,构建找矿预测模型,预测矿体空间位置,提出勘查工程布置建议。深化总结火山岩型铅锌银矿、金(铜)矿找矿预测研究,建立相关矿床“三位一体”找矿预测地质模型。为深部找矿作成矿预测依据。为东安金矿区深部找矿提供最佳靶区。
[Abstract]:This paper focuses on the epithermal hydrothermal gold deposits, through the study of ore-forming geological bodies, ore-forming structures and ore-forming structural planes, metallogenic processes, combined with the necessary large-scale special geological mapping and geophysical and geochemical exploration work. To construct prospecting prediction model, to carry out ore prospecting prediction research, to strengthen the application of the results, to provide reasonable suggestions for the layout of deep exploration projects in time, and to take the whole exploration area as the unit, A series of basic maps are compiled. The Dongan Yanshou gold ore area is an important rock gold mine area in the north of the Yichun-Yanshou metallogenic belt. Seven ore bodies have been found, all of which are concentrated in the west ore belt of the Dongan mining area, while the east ore belt is covered by the Sunwu formation of the Tertiary system. However, the metallogenic geological conditions of the east ore belt are similar to those of the western ore belt, and are closely related to the metallogenic subvolcanic rocks and hydrothermal alteration, which have great potential for prospecting. This work mainly uses the comprehensive means of geology and geophysical and geochemical exploration to analyze the geological characteristics of the area. The geological conditions of ore formation and the scale, form, occurrence and quality of orebody are studied in depth, and suggestions and bases for further detailed investigation are put forward. In this paper, the geological characteristics of ore deposits are studied and the ore-forming geological bodies are determined by taking Dongan gold deposit as the key working area. The ore-forming structure and ore-forming structure face, the characteristics of metallogenesis, the prediction model of ore-prospecting, the spatial location of ore-body, the layout of exploration engineering are proposed, and the research on prospecting of volcanic type lead-zinc-silver ore and gold (copper) ore is deepened. The geological model of "trinity" prospecting and prediction of related deposits is established, which provides the best target area for deep prospecting and metallogenic prediction in Dongan gold deposit area.
