辽吉活动带硼矿地质遗迹的地质特征及评价

Geological Characteristics and Evaluation of the Geological Remains of Boron Deposits in Liaoji Active Belt

辽吉活动带是华北陆块最具代表性的古元古代活动带之一,不仅记录了早期超大陆聚合—裂解动力学过程的重要信息,而且发育众多典型的前寒武纪地质遗迹景观。通过对活动带内发育的硼矿床及相关地质遗迹进行简要分析,认为区内主要发育基础地质大类地质遗迹,具体包括地层剖面、岩石剖面、构造剖面以及重要岩矿石产地4类,并阐述了硼矿床的地质特征、成因及形成演化过程。结合区内发育大量的地貌景观大类地质遗迹,分析认为两者相互融合将对地区经济建设、科学普及和旅游经济等方面具有重要价值。

Liaoji active belt is one of the most representative Paleoproterozoic active belts in North China block.It not only records the important information of the dynamic process of early supercontinent aggregation and fragmentation,but also develops many typical Precambrian geological relic landscapes.Through a brief analysis of the boron deposits and related geological relics developed in the active belt,it is considered that there are mainly basic geological types of geological relics developed in the area,including stratigraphic section,rock section,structural section and important rock and ore producing areas.Based on the above analysis results,the the geological characteristics,genesis and formation and evolution process of boron deposits are discussed.Combined with the development of a large number of geomorphic and landscape geological relics in the area,it is indicated that the integration of them will be of great value to regional economic construction,scientific popularization and tourism economy.
