RM2982 Quartz with kaolinite
Serrabal mine, Vedra, A Coruña, Galícia, SpainFloating 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 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.
Size: 11 x 7.8 x 5.9 cm.

RM2976 Magnesite
Impensada Mine (Magnesitas de Rubián), Pacios, O Incio, Lugo, Galicia, SpainThe Rubián Magnesite mines are a classic of Galician mineralogy. Currently these mines are active exploiting one of the largest deposits of magnesite in Spain. This specimen, which dates from the late 1970s, shows us a rich aggregate of lenticular crystals of this magnesium carbonate, brilliant, translucent, and with a very aesthetic orange color. It belongs from the Joan Astor collection, with his handwritten and another typed labels.
Size: 5 x 4.8 x 2.9 cm.
Found in ±1977.
