Voudourisite, Cd(SO4)·H2O, and lazaridisite, Cd3(SO4)3·8H2O, are two new minerals from the Esperanza Mine, Kaminiza Area, Lavrion Mining District, Greece. This small ancient mine is also the type locality of niedermayrite and katerinopoulosite. Further associated minerals are sphalerite, ...
Occurs chiefly as sulfide in galena, other minerals include anglesite (PbSO4), cerussite (PbCO3), mimetite (PbCl2.3Pb3-(AsO4)2) and pyromorphite [PbCl2.3Pb3(PO4)2)].|Lead sulfate occurs naturally in anglesite, one of three lead ores found in sufficient abundance to form mineable ...

They also contained a proportion of kaolinite clay from the San Jorge mine, located in the state of Baja California, Mexico, which has been reported to be a kaolin deposit with a composition of 19.46 wt% Al2O3 and 59.4 wt% SiO2 [17]. Table 1. Mixtures of kaolinite clay, Al2O3 and...
However, previous mineralogical studies pointed out the occurrence of essential Al, occupying a distinct site in the crystal structure of this mineral. Through the critical re-examination of the available literature and new crystal-chemical data collected on a specimen from the Monte Arsiccio mine, ...
