冀东滦南一带重磁异常特征及找矿意义
Characteristics of gravity and magnetic anomalies in Luannan area of eastern Hebei and their ore-prospecting significance
摘要
Abstract
By means of gravity and magnetic data processing and interpretation of Luannan area, the authors analyzed the metallogenic spatial distribution and the relationship between the magnetic and gravity anomalies in the sedimentary metamorphic iron ore deposits, described the characteristics of magnetic and gravity anomalies in this area which are characterized by banding distribution, expounded the gravity and magnetic anomaly characteristics of Gu′an-Changli fault zone in relation to the distribution of the magnetite. According to the relationship between the distribution of the Sijiaying-Macheng iron deposit and the magnetic and gravity anomalies, the authors made anomaly inversion comparison through drilling verification and demonstrates the ore-related magnetic anomalies in Luannan area. Combined with regional tectonic and magnetic characteristics, the authors summed up the experience obtained in the exploration process of BIF iron ore deposit in this area, and predicted the ore-forming prospect of this type of ore deposits.关键词
