摘要:

鄂尔多斯盆地是中国煤、油气、铀等资源的重要勘查基地,东北部、西部和东南部地区先后发现了数个超大型、大中型砂岩型铀矿床,西南部地区找矿标志和找矿方向则一直是该盆地铀资源勘查的难点。通过对鄂尔多斯盆地西南部镇原地区地质构造背景、地层结构、岩性岩相、水文地质、古气候等基本特征开展综合研究,认为研究区下白垩统洛河组具备有利于砂岩型铀成矿的地质条件,包括早白垩世以来适宜流体运移的构造背景,洛河组风成相砂岩厚度稳定、渗透性较好,泥-砂-泥或泥-砂-钙(钙质砂岩)/泥的地层结构,蚀源区和盆地盖层较高的U含量,连通的地下水补-径-排体系,干旱—半干旱为主的古气候条件,丰富的油气还原介质等。通过对铀矿物类型及赋存状态研究,提出研究区主要为沥青铀矿,部分为含钛铀矿物。铀矿物赋存状态与盆地东北部直罗组具有较大的差别,主要与针状磷灰石、长石、绿泥石、伊蒙混层、白云石、黄铁矿等伴生,与炭屑等还原介质没有直接的伴生关系。其中砂岩型铀矿与磷灰石伴生关系尤其重要。通过成矿条件的分析,指出断裂构造控制的油气上升部位可能是下一步的有利勘查区域。

Abstract:

Ordos Basin is an important exploration base for coal, oil and gas, uranium and other resources in China. Several large and medium-sized sandstone-type uranium deposits are discovered in the northeastern, western and southeastern margins, the prospecting breakthrough in southwestern margin is always difficult in uranium exploration. Through the comprehensive study on the characteristics of tectonic setting, stratigraphic structure, lithology and lithofacies, hydrogeology and paleoclimate in Zhenyuan area, the southwestern margin of Ordos Basin, it is concluded that the Lower Cretaceous Luohe Formation has the conditions for the formation of sandstone-type uranium deposit in study area, such as the tectonic setting is favorable for fluid migration since Early Cretaceous, the aeolian sandstones of Luohe Formation have stable thickness and good permeability, the structure is mud-sand-mud or mud-sand-calcium(calcareous sandstone)/mud, the U contents in source and caprock layers are high, the groundwater runoff system is connected, the climatic condition is arid-semiarid, the reduction media of oil and gas is abundant. By studying the types and occurrence states of uranium minerals, it is proposed that the main type is pitchblende, and a small part is titanium-containing uranium minerals. The occurrence states of uranium minerals are quite different from Zhiluo Formation in the northeastern margin of Ordos Basin, which are mainly associated with acicular apatite, feldspar, chlorite, illite/smectite formation, dolomite and pyrite, etc., but not directly associated with carbon debris and other reducing media. Among them, the discovery of the associated relationship between sandstone-type uranium deposits and apatite is particularly important. According to the analysis of metallogenic conditions, the rising position of oil and gas controlled by fault structure may be the favorable exploration direction for the next step.
