如众所知,某些铀矿床的形成和分布与岩石的氧化还原性能密切相关,因此研究铀矿床地球化学环境对铀矿预测及找矿勘探有重要意义。根据3701矿床含矿地质体不透水这一特点,本文作者从钻孔岩心系统地取得矿床主要地段各部位岩矿石样品,进行了岩石还原容量(△Eh值)测定,以直接了解矿床各部位岩石的氧化还原性能,并参考岩石特征和某些岩石地球化学指标,对矿床进行了岩石氧化还原带的划分;同时探讨了此分带在铀矿找矿勘探中的意义。
As we all know, the formation and distribution of some uranium deposits are closely related to the redox properties of the rocks. Therefore, it is of great significance to study the geochemical environment of uranium deposits for uranium prospecting and prospecting. According to the characteristics of impermeable ore bodies in 3701 ore deposit, the author systematically obtained rock ore samples from various parts of the ore deposit and determined the rock reduction capacity (ΔEh value) to directly understand the rock mass of each part of the ore deposit The redox properties of the ore deposits were also studied. The lithological redox zones of the ore deposits were classified with reference to the characteristics of rocks and some geochemical indicators of rocks. The significance of this zoning in the prospecting of uranium deposits was also discussed.
