基于证据权重法的海南岛金多金属矿成矿预测研究 摘要： 金多金属矿是一种重要的金属矿产资源，对于矿产资源评价和开发 具有重要意义。本文以海南岛金多金属矿为例，采用证据权重法对该区 域的成矿预测进行研究。首先，通过对该地区地质特征和成矿规律进行 分析，选择了岩浆热液矿化、岛弧隆起矿化以及构造变形矿化等三种成 矿类型进行研究。然后，针对每种成矿类型，选取相应的成矿因素，并 利用专家调查和文献资料分析等方法，建立了三种成矿预测模型。最 后，采用证据权重法对三种模型的预测结果进行综合评价。结果表明， 三种成矿类型中以岩浆热液矿化概率最高，其次为岛弧隆起矿化和构造 变形矿化。 关键词：证据权重法；海南岛；金多金属矿；成矿预测 Abstract: Gold polymetallic deposit is an important metal mineral resource, and it is of great significance for mineral resource evaluation and development. In this paper, taking the gold polymetallic deposit in Hainan Island as an example, the evidence weight method was used to study the mineralization prediction of this area. Firstly, according to the geological features and mineralization law of the area, three types of mineralization, namely magmatic hydrothermal mineralization, island arc uplift mineralization, and structural deformation mineralization, were studied. Then, for each type of mineralization, corresponding mineralization factors were selected, and three mineralization prediction models were established by using expert investigation, literature analysis and other methods. Finally, the evidence weight method was used to comprehensively evaluate the prediction results of the three models. The results showed that the probability of magmatic hydrothermal mineralization was the highest among the three types of mineralization, followed by island arc uplift mineralization and structural deformation mineralization.
