本文重点论述方解石中非晶质铀矿偏球粒的形成。作者认为方解石被非晶质铀矿交代置换是由于UO_2晶体纤维晶生长晶棱——显微尖棱结晶压力所引起的CO_2薄膜中的压力升高,可看成方解石被非晶质铀矿偏球粒界面层(薄膜)溶解的过程,这是非晶质铀矿偏球粒生长的矿物学标志。文中对非晶质铀矿偏球粒表面生长的机理和界面薄膜中可能的化学反应进行了讨论。 This article focuses on the formation of amorphous spherulites in calcite. The authors believe that the replacement of calcite with non-crystalline uranium deposits is due to the increase of pressure in the CO_2 film caused by the crystal growth of the UO 2 crystal fiber crystal, Spherulite interface layer (thin film) dissolution process, which is the mineralogy of the amorphous uranium spherulites growth mineralogical mark. In this paper, the mechanism of the surface growth of amorphous uranium pellets and the possible chemical reaction in the interface films are discussed.
