摘要:
铀资源是十分重要的战略性能源矿产资源。秦岭地区是中国重要的铀矿成矿区，华阳川地区发现的华阳川铀多金属矿位于北秦岭铀成矿带的东段。目前，在华阳川及周边已发现多处铀矿及铀矿化点，铀矿找矿潜力巨大。为解决华阳川地区复杂地形条件下隐伏硬岩型铀矿资源勘探及外围实现找矿突破对地球物理勘查方法技术的需求，在华阳川铀矿区进行了航空伽玛能谱/磁法、航空瞬变电磁/磁法、航空重力/磁法等综合航空地球物理勘查系统不同高度和不同尺度的航空地球物理测量，同时在地面开展了相应的重、磁、放射性测量、不同装置的激电测深及多种电磁测深等地球物理勘查，对这些方法在复杂地形条件下铀矿资源勘查中的有效性和适用性进行了验证，并在外围找矿有利区段开展了示范性勘查工作，在此基础上筛选出了复杂地形条件下隐伏硬岩型铀矿不同勘查阶段的地球物理勘查方法技术组合，为华阳川地区铀矿的找矿突破提供了地球物理勘查方法技术支撑，对其他复杂条件区的隐伏铀矿勘查及其他隐伏金属矿的勘查工作也具有参考价值。
Abstract:Uranium resources are very important strategic energy mineral resources. Qinling area is an important uranium ore forming area in China. The Huayangchuan uranium polymetallic deposit found in Huayangchuan area is located in the eastern part of the North Qinling uranium metallogenic belt. At present, many uranium deposits and uranium mineralization points have been found in and around Huayangchuan, and the uranium prospecting potential is huge. In order to meet the requirements of geophysical exploration methods and technologies for the exploration of concealed hard rock type uranium resources under complex terrain conditions in Huayang Chuan area and the realization of ore prospecting in the periphery, aerial geophysical surveys at different heights and scales have been carried out in Huayang Chuan uranium mining area with integrated airborne geophysical exploration systems such as airborne gamma ray spectrometry/magnetic method, airborne transient electromagnetic/magnetic method, airborne gravity/magnetic method, etc. At the same time, corresponding gravity, magnetic The effectiveness and applicability of these methods in the exploration of uranium resources under complex terrain conditions have been verified by geophysical exploration such as radioactive survey, IP sounding of different devices and multiple electromagnetic sounding, and demonstration exploration work has been carried out in the favorable areas for prospecting in the periphery. On this basis, the combination of geophysical exploration methods and technologies in different exploration stages of concealed hard rock type uranium deposits under complex terrain conditions has been screened out, It provides the geophysical exploration method and technology support for the breakthrough of uranium ore prospecting in Huayangchuan area, and also has reference value for the exploration of hidden uranium deposits and other hidden metal deposits in other complex conditions.
