... chains (94 compounds/15 minerals); (4) infinite sheets (353 compounds/79 minerals); and (5) frameworks (186 compounds/13 minerals). Within each of these major categories, structures are sub-divided on the basis of increasing connectivity of uranium (nearly always uranyl) polyhedra. In addition...

... and gas; see example in Fig. 4 B–E). Daughter minerals show a highly diversified mineralogy. Phyllosilicate daughter minerals can be abundantly observed as pseudohexagonal sheets. Other common daughter minerals include colorless, low-birefringent quartz, granular translucent feldspar masses, and a highly...

... of temperatures from 3.3 to 30.5 °C ( Fig. 7a, b ), but the data can be separated into populations based on different samples and FIAs ( Fig. 7a, b ). Thus, quartz from hyalophane-bearing pegmatite far from REE mineralization (4 FIAs, Fig. 7a ) has two dominant populations at 9 to 13 °C and 24 to 26 °C, whereas...

.... These minerals contain the autunite-type sheet, of composition [(UO 2 )(PO 4 )] − , which involves the sharing of equatorial vertices of uranyl square bipyramids with phosphate tetrahedra. In each of these structures, Cu 2+ cations are located between the sheets in Jahn–Teller-distorted (4 + 2) octahedra...
