1977年,在以色列中部的Judean沙漠及Negev北部地区发现了铀含量高达230ppm,平均为110ppm的磷灰岩以及一些次生铀矿物。之后的几年,对矿化的空间分布、矿化与含矿化岩石的关系、岩矿鉴定及成因等进行了野外和室内的综合研究。次生铀矿化有如下几方面特征; 1.区域地质上,矿化区东濒死海裂谷,属叙利亚弧构造的一部分。矿化区内,Hatrurim向斜和Makh(?)esh Qatan背斜与死海裂谷平行,呈NNE向。上白垩(?)第三系广泛出露,主要岩石有白云岩、灰岩、泥灰岩、变质磷灰岩、白垩、砾岩等,此外,由这些岩石风化而来的土壤也很发育。次生铀矿化主要产在变质磷灰岩和含石膏层或脉的土壤中。
In 1977, apatites with as high as 230 ppm uranium and an average of 110 ppm uranium and some secondary uranium minerals were found in the Judean Desert and northern Negev in central Israel. In the following years, field and indoor comprehensive studies were conducted on the spatial distribution of mineralization, the relationship between mineralization and mineralized rocks, the identification and genesis of rock and mine. Secondary uranium mineralization has the following characteristics: 1. Geologically, the mineralized area is near the Dead Sea Rift, and is part of the Syrian arc. In the area of mineralization, the Hatrurim syncline and the Makh (?) Esh Qatan anticline are parallel to the Dead Sea rift and appear in a NNE direction. Upper Cretaceous (?) Tertiary is widely exposed. The major rocks are dolomite, limestone, marl, metamorphic apatite, chalk, conglomerate, etc. In addition, the soils weathered from these rocks also developed. Secondary uranium mineralization is mainly produced in metamorphic apatite and gypsum-bearing layers or veins.
