铀矿床分布在复背斜中部在深大断裂交叉部位。矿床产在浅色花岗岩的外接触带,与文德期砂泥质沉积层的接触地段,辉长岩岩株及斑状花岗岩和花岗细晶岩的小岩休侵入其中。矿石为钠长石-磷灰石成分的交代岩,铀石为主要铀矿物,碎裂岩带为主要容矿构造,碎裂岩带中的矿物被密集的微裂隙网破碎。在下部含矿交代岩主要沿斑状花岗岩和花岗细晶岩发育;在上部主要沿砂岩和粉砂岩发育。交代岩的主要新生矿物是钠长石和磷灰石,其次是绿泥石、碳酸盐、水云母和铀矿物。细分散状红色亦铁矿染为交代岩的明显标志。岩石的交代改造作用从钠长石化开始,绿泥石-铀石组合叠加在已钠长石化的岩石上。按矿物的形成时间,磷灰石占据中间位置,部分与钠长石和铀石重叠。在钠长石化的岩石裂隙带内产出的矿石最富。铀含量0.0n％—0.n％的贫矿石和一般矿石在矿床中占重要地位,在遭受最强烈的钠长石化后破碎的局部地段,铀含量可达到1％—3％。含矿交代作用是在200—280℃温度范围内,在含有高浓度磷的碱性溶液作用下进行的。根据成分特征,北哈萨克斯坦含矿交代岩与加拿大比弗洛支湖矿床的交代岩很相似。
Uranium deposits are distributed in the middle part of the anticlinorium at the intersection of deep faults. The ore deposits intruded into the outer contact zone of the light-colored granite, contact with the sand-shaly sediments in Wende period, the gabbro rocks, and the small rocks of the porphyritic granite and granodiorite. The ore is the metamorphic rock of the albite-apatite composition, with uranium as the main uranium mineral and the fractured rock zone as the main ore-bearing structure. The minerals in the fractured rock zone are crushed by the dense micro-fracture network. The lower ore-bearing metasomatism develops mainly along plagioclase granodiorite and granitic sillimanite; the upper part mainly develops along sandstone and siltstone. The major new-born minerals of the metamorphic rocks are albite and apatite, followed by chlorite, carbonate, hydromica and uranium minerals. Fine reddish brown iron ore stains as a clear indicator of metamorphic rocks. Interpretation of rock alteration From the beginning of albite, chlorite - uranium assemblage superimposed on the albite rock. According to the mineral formation time, apatite occupies the middle position, partly overlapping with albite and uranium. The ore is the most abundant in the feldspar rock zone. Uranium content 0.0n% -0.n% of the poor ore and ore in the ore occupies an important position in the most aggravated by the most severe petrochemical fragmentation of local areas, uranium content can reach 1% -3%. The ore-bearing metasomatism is carried out at a temperature in the range of 200-280 ° C under the action of an alkaline solution containing a high concentration of phosphorus. Based on the compositional characteristics, the ore-bearing rocks in the northern Kazakhstan are similar to the metasomatists in the Beaverochow deposit in Canada.
