河北杨营铁矿地质特征及深部找矿远景
|
摘要
本项目依托了河北丰宁顺达铁矿资源整合勘查项目,该项目成果获得了第六届"中国有色金属地质找矿成果二等奖"。通过综合研究以往地质成果,总结了本区磁铁矿床成因及找矿标志,并评价了找矿远景。充分搜集了华北地区沉积变质岩型磁铁矿床和河北地区超基性岩型超贫磁铁矿床的有关地质资料,综合分析了成矿地质条件、控矿因素,紧密结合找矿成果资料,充分论述了地层特征、构造活动和岩浆活动与矿化的关系,评述了磁异常与矿体分布之间的联系。依据已知矿体的规模、形态特征,评价了杨营磁铁矿床的找矿远景,对区域内沉积变质和超基性岩型两种类型铁矿找矿方面起重要指导作用。
This project relies on the Fengning Shunda of Hebei iron ore resources integration exploration project,the project has won the sixth " China non-ferrous metal geological prospecting achievements second prize".Based on the comprehensive study of the past geological achievements,this paper summarized the genesis and prospecting criteria of the magnetite deposit in this area,and evaluated the prospecting prospect,fully collected sedimentary metamorphic type magnet deposit in north China and Hebei region ultrabasic rock type super poor magnet deposit related to geological data,comprehensively analyzed on the ore-forming geological conditions,ore-controlling factors,combining information ore-prospecting achievements,fully discussed the formation characteristics,tectonic activity and the relationship between magmatism and mineralization.The connection between the magnetic anomalies and the ore body distribution were reviewed.Based on the known size and morphological characteristics of ore bodies,the prospecting prospect of Yangying magnetite deposit was evaluated,which provides important guiding significance in g the prospecting of two types of iron ores in the region,namely sedimentary metamorphism and ultrabasic rock type.
