Geophysical-geochemical anomalies and prospecting significance of boron deposits in Ertaizi area, eastern Liaoning Province

摘要:
辽东-吉南是我国重要的硼矿矿产资源产地，区内大型、超大型硼矿床众多. 二台子硼矿位于辽东－吉南成矿带的中部，矿床规模为中型，勘探、开发较早并已闭坑. 为了分析二台子硼矿外围硼矿资源潜力，对区域物化探资料进行了研究. 结果显示，区域化探异常和重磁异常在研究区的中间都出现了错位现象，由此推断F1断裂的存在. 根据地质资料，F1断裂的北东侧是由一个向斜和一个背斜组成的复式褶皱，褶皱轴走向北东. 二台子硼矿位于背斜的东翼南端，位于航磁异常内，位于剩余重力异常的边部. 重磁异常相伴或重力异常区内的磁异常是寻找硼矿的有利部位. 沿背斜东翼向北有多处与二台子硼矿床所在位置相似特征，特别是北部褶皱的转折端，重磁异常与化探异常相互套合，是寻找硼矿的有利部位.
Abstract:The eastern Liaoning-southern Jilin area is an important boron mineral resource base in China, with numerous large and super-large boron deposits. The medium-sized Ertaizi boron deposit, located in the central part of eastern Liaoning-southern Jilin metallogenic belt, had been explored and developed early before it was closed. To evaluate the boron resource potential in the periphery of Ertaizi boron deposit, the paper studies the regional geophysical and geochemical data. The results reveal that both the regional geochemical anomaly and gravity-magnetic anomaly show a dislocation in the middle of the study area, suggesting the existence of F1 fault. According to the geological data, on the northeast side of F1 fault, there is a complex fold composed of a syncline and an anticline, with a NE-trending fold axis. The Ertaizi boron deposit is situated at the south end of eastern wing of the anticline, within the aeromagnetic anomaly and on the edge of residual gravity anomaly. Areas where gravity-magnetic anomaly coincide or where magnetic anomaly occur within gravity anomaly zones are favorable targets for boron prospecting. A few areas along the eastern wing of the anticline to the north exhibit characteristics similar to those of Ertaizi boron deposit, particularly at the hinge of northern fold where gravity-magnetic anomalies overlap with geochemical anomalies, making these areas highly prospective for boron exploration.
