| 中文摘要: |
| 大兴安岭成矿带是我国重要的成矿区带之一，中南段发现了多处银铅锌多金属矿，区内工作程度均较高，便于建立准确性较高的找矿和预测模型。本文以大兴安岭中南段区域成矿地质背景为基础，借助GIS技术，探讨研究区各成矿相关元素的空间分布特征，采用多重分形方法对成矿潜力进行了评估，利用C-A、S-A模型分析了元素的分布规律，并运用模糊证据权方法，针对研究区银铅锌多金属矿开展以地质、地球化学资料为主的预测研究，探讨了研究区成矿与构造、地层和岩浆岩之间的关联性规律，初步开展找矿远景区的预测评价，结果显示，矿产与断裂构造、二叠系地层及燕山期岩浆活动之间具有密切联系。最终圈定11个远景区，通过计算远景区相关参数，根据其规模及已知矿床的分布情况，将远景区划分为四个一级远景区，两个二级远景区，五个三级远景区，其中一级远景区为找矿最有利的区域，旨在为该地区的矿产资源开发提供科学依据和决策支持。 |

| The Greater Khingan Mountains metallogenic belt is one of the important metallogenic belts in ChinaMultiple silver lead zinc polymetallic deposits have been discovered in the central and southern sections，and the level of work in the area is relatively high，which facilitates the establishment of accurate prospecting and prediction modelsIn this article，it is based on the geological background of mineralization in the central and southern sections of the Greater Khingan RangeWith the help of GIS technology，the spatial distribution characteristics of various ore-forming related elements in the study area are exploredThe multifractal method is used to evaluate the ore-forming potential，and the C-A and S-A models are used to analyze the distribution patterns of elementsFuzzy weight of evidence method is applied to conduct predictive research on the silver lead zinc polymetallic deposits in the study area，mainly based on geological and geochemical dataThis study discussed the correlation between mineralization and structure，strata and magmatic rocks in the study area，and preliminarily carried out the prediction and evaluation of prospecting prospectsThe results showed that there was a close relationship between minerals and fault structures，Permian strata and Yanshanian magmatic activityFinally，11 prospective areas were delineatedBy calculating the relevant parameters of the prospective areas and based on their scale and the distribution of known mineral deposits，they were divided into four primary prospective areas，two secondary prospective areas，and five tertiary prospective areasAmong them，the primary prospective area was the most favorable area for mineral exploration，aiming to provide scientific basis and decision support for the development of mineral resources in the region |
