| 中文摘要: |
| 石台地区因第四系覆盖广泛、基岩露头较少，为深入了解该区成矿潜力，本文选取地质条件具代表性的黄土岭地区为研究区，旨在通过地球化学特征和地质要素进行成矿预测，为后续找矿提供依据。通过开展 1∶10000土壤地球化学测量，检测 V、Ag、Mo等 13种元素含量，运用相关分析、R型聚类分析、因子分析、Q型聚类分析和异常分析等方法解析地球化学特征，并综合地质要素进行成矿预测。研究表明 V、Ag、Mo、 Bi、As、Sb为区内主要成矿有利元素，V与 Ag、Mo、As、Sb存在显著成因关联，综合异常 AP-3区显示成矿有利元素与黑色岩系密切相关，在异常 AP-3区的探槽验证揭露了多个 V、Mo和 Ag伴生矿(化)体。研究认为，黄土岭及附近地区黑色岩系，具有较好的 V、Ag、Mo找矿潜力，花岗闪长岩岩体接触带也有 Cu元素的成矿可能。 |
| 英文摘要: |
| Due to the extensive coverage of the Quaternary system and the limited outcrops of bedrock in theHuangtuling, Shitai, which possesses representative geological conditions, was selected as the study area to gain adeeper understanding of the mineralization potential in the region. The aim is to conduct mineralization predictionbased on geochemical characteristics and geological factors, providing a basis for subsequent prospecting. By con.ducting a 1∶10000 soil geochemical survey, the content of 13 elements such as V, Ag, and Mo was detected. Meth.ods such as correlation analysis, R-type cluster analysis, factor analysis, Q-type cluster analysis, and anomalyanalysis were employed to analyze the geochemical characteristics, and mineralization prediction was carried out byintegrating geological factors. The study indicates that V, Ag, Mo, Bi, As, and Sb are the main favorable elements formineralization in the area. There is a significant genetic association between V and Ag, Mo, As, and Sb. The compre.hensive anomaly AP-3 area shows that the favorable elements for mineralization are closely related to the blackrock series. Exploratory trenches in the anomaly AP-3 area have revealed multiple associated ore (mineralization)bodies of V, Mo, and Ag. The study suggests that the black rock series in Huangtuling and nearby areas have goodprospecting potential for V, Ag, and Mo, and there is also a possibility of Cu mineralization in the contact zone ofgranodiorite rock bodies. |
