山东省齐河大张铁矿地质特征及找矿前景

Geological Characteristics and Prospecting Potential of Dazhang Iron Deposit in Qihe County of Shandong Province

摘要:

近年来，山东齐河地区铁矿找矿取得了较大进展，为了更好的指导区内铁矿勘查工作，通过研究大张地区铁矿地质特征、地球物理特征，剖析其矿床特征，建立找矿标志，并对今后铁矿找矿方向进行研究。通过对重磁测量成果分析，认为该区具有“重磁同高”的异常特征，具有一定规模和强度的重、磁异常，是寻找该类铁矿床的重要标志。通过对矿区地质特征和控矿因素的分析，认为该区具有较大的成矿潜力。

Abstract:

In recent years, great progress has been made in iron ore exploration in Qihe area of Shandong province. In order to better guide the iron ore exploration, through analysis on geological, geophysical characteristics and deposit characteristics of Dazhang iron deposit, prospecting criteria has been established, and the exploration direction in the future has been studied. Through analysis on gravity and magnetic survey, it is considered that this area has the characteristics of "gravity and magnetic are the same", and has a certain size and strength, gravity and magnetic anomaly. It is an important symbol for searching this kind of iron ore deposit. Based on analysis of geological characteristics and controlling factors in the mining area, It is regarded that the area has the potential of large metallogenic potential.
