The organics and impregnations of uranium are everywhere coextensive.

有机物和铀的浸染到处是共同延伸的。

Vanadium mainly exists as independent minerals or in clay minerals in the form of isomorphism, with a small amount absorbed by clay minerals and limonite. Nickel mainly exists as independent minerals. Molybdenum occurs as colloidal sulfides with carbon, sulfur and clay, and forms molybdenite through thermal metamorphism. Uranium is unevenly scattered in collophanite and carbonaceous_argillaceous materials in the form of isomorphism or adsorption. REE mainly occur in collophanite in the form of isomorphism. Copper, lead and zinc chiefly exist in sulfides or sulfo_arsenides and are concentrated in the metallic layer.

钒或以独立矿物存在,或以类质同象赋存在粘土矿物中;镍主要以独立矿物存在;钼主要与碳、硫、粘土一起呈钼硫化物胶状集合体,经热接触变质作用后形成辉钼矿;铀呈不均匀分散在胶磷矿和碳泥质中,呈类质同象或吸附状态存在;稀土元素主要呈类质同存在于胶磷矿中,部分呈吸附状态存在;铜、铅、锌主要以硫化物和硫砷化物等存在,多富集在金属层中。

Ordos basin accumulates various energy resources. Taking the oil, gas, coal and uranium in the basin as subjects, the scientists of China's State "973" multi-energy minerals enrichment project study the scientific issues of interest concerning the coexistence and accumulation of energy minerals in one basin, such as the material base and geodynamical settings the accumulation mechanism and enrichment environment, and the temporal and space distribution and control factors. This interdisciplinary study provides a new perspective on comprehensively understanding energy geosciences.

我国国家&973&多种能源矿产项目的科学家以富集多种能源矿产于一身的鄂尔多斯盆地为研究地区,以油、气、煤、铀为研究对象,探讨能源矿产同盆共存富集成藏的物质基础与地球动力学背景、成藏机理与富集环境、时空分布与主控因素等科学问题,这是通过多学科交叉综合研究能源地球科学的新视角。

Chemical analyses of ores sampled from different elevation at the representative Zoujiashan uranium deposit indicate that Fe〓O〓, FeO, MgO and P〓O〓 increase evidently with depth which is related to alteration of haematite, chlorite and apatite, Na〓O and Na〓O+ K〓O also increase with depth, reaching a maximum of Na〓O at 911 meters below the surface, which suggests alkaline alteration increases downwards. At depth of 90 meters below sea level, where the boundary of the two cycles of the volcanic rocks is located, CaO reaches the maximum, representing maximum of alteration of fluorite.

对典型矿床不同富集标高矿体的化学全分析结果表明:随深度增加,Fe〓O〓、FeO、MgO及P〓O〓的含量有明显增高的趋势,这与赤铁矿化、绿泥石化及磷灰石化有关;-90m标高的CaO含量最高,达17.67%,反映这一部位的萤石化最发育;Na〓O及Na〓O+K〓O的含量由浅入深也存在明显的增高趋势,且Na〓O的含量在911m深处为最高,这充分显示碱交代作用从上到下有增强的趋势,而钠长石化在911m处最强烈。
