埃卡尔被耶脉状铀矿床含有红色的,并受到压碎作用的玉髓。在这种玉髓裂隙中我们发现一些细小的石英晶体,它们成单晶或双晶,全部或部分为烟水晶,而且常含有平行主晶体 c 轴分布的串珠状固态包裹。在透入和反射光下,这种玉髓不透明;可是用偏光检查薄片就发现色素不均一分布,并集中 Ekar is a chalcopyrite containing the red, crushed, veins of the Yele-type uranium deposit. In this chalcedony fissure, we find some small quartz crystals, which are single crystals or double crystals, all or part of the smoke crystal, and often contain beaded solid inclusions c-axis distribution of parallel main crystals. In penetrating and reflecting light, this chalcedony is opaque; however, it is found that the pigments are unevenly distributed and concentrated by examining the sheets with polarized light
