Detailed X-ray single-crystal structure refinements and complete (SIMS + EMPA) microprobe chemical analyses of a series of non-metamict samples of hellandite recently found in Latium (Italy),together ...
Heretofore the nomenclature of axinites was very simple: the only name accepted by everybody was "axinite" itself, sometimes associated with the adjective "manganous". Since most, if not all, axinites...

The crystal structures of the high- and low-temperature forms of Bristol, Conn., chalcocite have been investigated with single-crystal methods. At 125 0C., high-chalcocite has lattice constants a=3.95...
Four instances of imperfection or disorder in crystals are presented and interpreted in this paper. They are all obtained through the studies of crystal surfaces of silicon carbide and hematite. This ...
