黑铅铀矿(richetite)自1947年J.F.Vaes首次描述以来就作为一个矿物种列入铀矿物学的文献中,但其研究程度很差,又令人怀疑它是否存在于自然界。当时,从扎伊尔申戈洛布维铀矿床采得两块标本,将黑色扁平的板状晶体以比利时地质学家Emile Richet的名字命名为richetite。该矿物生长在结晶很好的硅钙铀矿晶体中,定性化学分析表明含有U,Pb;但没有Ba,Ca,Mg,Si。也研究了矿物的光性。 1958年C.Frondel重复了Vaes的描述,但是,对黑铅铀矿作为一个矿物种提出了怀疑。他认为,矿物呈黑色是由于含有四价铀所致。 1959年J.Protas对保存在Sorbon陈列馆采自
The richetite was included in the uranium mineralogy literature as a mineral species since its first description by J.F. Vaes in 1947, but its degree of research is poor and it is doubtful whether it exists in nature. At that time, two specimens were taken from the Shengorobuwei uranium deposit in Zaire, and the black flat plate crystal was named richetite by the Belgian geologist Emile Richet. The mineral grows in a well-crystallized crystalline form of calcium-calcium uranium. Qualitative chemical analyzes show U, Pb; but no Ba, Ca, Mg, Si. Also studied the phototropism of minerals. C. Frondel repeated the description of Vaes in 1958, however, doubting the presence of black-lead uranium as a mineral. In his opinion, the black mineral is due to containing tetravalent uranium. 1959 J.Protas is collected from the Museum of Preservation in Sorbon
