地质内涵法在化探矿化信息提取中的应用探讨——以山东五井——悦庄一带为例

Discussion on the Application of Geological Connotation Method in the Extraction of Geochemical Exploration and Mineralization Information——Taking WujingYuezhuang Area in Shandong as an Example

摘要:

传统化探数据处理方法是先用数学方法（多元统计、衬值、分形等）圈定异常，之后再对异常进行评价，同一批化探数据，不同的人其评价结果可能有所不同，评价存在一定程度的主观性。笔者通过研究地质成矿规律来限定元素的组合规律，即将地质、地球化学规律融合于数学规律之中。通过对山东省1∶5万五井幅、悦庄幅大量区域化探数据进行重新处理，赋予数据以客观的地质内涵，来圈定成矿类型异常图、成矿强度异常图等带有特定地质意义的异常图，从而快速筛选与成矿有关的异常。定量分析了区内金铜等主要矿产的成矿强度，据此在区内圈定成矿远景区1处，圈定找矿靶区3处，有效指导了区内的地质找矿工作。

Abstract:

Traditional geochemical data processing methods is to use mathematical methods (multivariate statistics, contrast values, fractals, et al.) to delineate anomalies, and then evaluate anomalies. Different people with the same batch of geochemical data may have different evaluation results. There is a certain degree of subjectivity in the evaluation. Through studying the laws of geology and mineralization, the combination of elements has been limited, that is integrating the laws of geology and geochemistry with the laws of mathematics. Through reprocessing a large number of regional geochemical prospecting data of Wujing and Yuezhuang with the scale of 1∶50,000 in Shandong province, the data is given objective geological connotations to delineate the abnormal maps of metallogenic types and the abnormal maps of metallogenic intensity with specific geology. Significant anomaly maps, so as to quickly screen the anomalies related to mineralization, and quantitatively analyze the mineralization intensity of the main target minerals such as gold and copper in the area. Based on this, 1 mineralization prospect in the area and 3 prospecting target areas are delineated. Department, guided the geological prospecting work in the area.
