老湾金矿成矿特征及成矿规律研究

Study on the metallogenic characteristics and ore-forming regularity of Laowan gold-bearing deposit

老湾金矿带分布在桐柏县城西北部。通过对老湾金矿的矿床特征进行研究,综合前人的研究成果,归纳总结出该矿床的成矿要素,并且对矿床的成矿模式进行了初步探讨。研究表明,老湾金矿带受韧性剪切带控制。通过对区内地质、矿产、物探、化探等资料的综合分析,并结合野外调查和室内研究,分析了老湾金矿的成矿物理化学条件和成矿机制。

Laowan gold-bearing deposit is located in the northwest of Tongbo country. Through the study of geological characteristics of Laowan gold-bearing deposit, and combined with the available data, the metallogenic factor of the deposit was summarized, and the metallogenic model was discussed. It is concluded that Laowan gold-bearing deposit is controlled by the ductile shear zone. By analyzing the information about the geology, minerals, as well as geophysical and geochemical exploration, and based on the field investigation and office study, the physical and chemical conditions and metallogenic mechanism of Laowan gold-bearing deposit were analyzed.
