关于沥青铀矿的合成实验,前人做过许多工作,但多是在高温高压下进行的。1954年J·W·Gruner曾报导过在50℃及室温下做过实验,1958年 L·J·Miller也提到过在25℃下合成沥青铀矿的问题。但他们的合成产物只是雏晶,未得到理想的X射线德拜图。也未见有关合成矿物学方面的详细报导。人们很早就知道产于砂岩、煤、碳酸盐岩、硅岩、黑色页岩等中的沥青铀矿与黄铁矿的关系非常密切。它们的矿物学和地球化学的研究表明:在同生(成岩)矿床中,沥青铀矿与胶状黄铁矿形成共生组合,并沿黄铁矿边缘分布,或局部交代黄铁矿。在后生(再造)矿床中,沥青铀矿依赖黄铁矿及其蚀变产物赤铁矿而存在,形成沥青铀矿与
On the synthesis of uranium pitch experiments, many people have done a lot of work, but mostly at high temperature and pressure carried out. In 1954, J.G. Gruner has reported experiments at 50 ° C and room temperature. In 1958, L. Miller also mentioned the problem of synthesizing pitch uranium at 25 ° C. But their synthesis product is only a crystallite, did not get the ideal X-ray de Bay figure. No detailed report on synthetic mineralogy has been found. It has long been known that bitumen uranium deposits in sandstone, coal, carbonate, silicalite, black shale, etc. have a very close relationship with pyrite. Their mineralogical and geochemical studies show that in the symbiotic (diagenetic) deposits, bitumen uranium and colloidal pyrite form a symbiotic assemblage that distributes along the pyrite margins, or locally interprets pyrite. In the epigenetic (reworked) deposit, bitumen uranium deposits rely on pyrite and its alteration product hematite to form asphaltic uranium deposits and
