RM2111 Cheralite - Grayite, Brockite
Brabant Farm 168, Karibib, Erongo, NamibiaThese specimens show yellowish nodules included in a feldspar matrix. First SEM-EDS analysis have yielded a phosphate of Th and Ca, with minor Pb. XRD has shown patterns of "bravantite", the old name for cheralite and brockite. The chemical base formula for these species are: grayite (Th,Pb,Ca)(PO4)·H2O; cheralite CaTh(PO4)2; brockite (Ca,Th,Ce)(PO4)·H2O. REE has not been found in EDS.
We could say that this yellow nodules belongs from altered monazite, formed by mixed species cheralite-grayite, with minor brockite. Accompanied in matrix by meta-autunite. We will send the full report.

RM2532 Quartz with kaolinite and limonite
Serrabal mine, Vedra, A Coruña, Galícia, SpainAlmost floating druse of quartz crystals forming pineapple growths, with a good luster and a slightly yellowish hue. On the backside, also crystallized, we can see the typical kaolinite layer of this deposit. It is accompanied by a limonite nodule that was probably pyrite.
These specimens were collected in this A Coruña quarry that exploits quartz, one of the main mines in the world due to the quality and quantity of its reserves. The mine was discovered in 1968 by three Galicians who gave their name (from their surnames SEñarís, RAma and BALboa) to the concession and who found it while exploring these mountains in the Pico Sacro area in search of "seixo" (from the Galician: hard white rock) of good quality.
