RM1763   Smoky-Morion quartz

Cañadas farm, Cerro de la Higuera, Montejícar, Granada, Andalucía, Spain

Montejícar is located midway between Granada and Jaén, in the northern limit of the province of Granada. This area is known among mineral collectors for the excellent quartz, smoked to morion, doubly terminated and with very poorly developed prism faces, which gives them a characteristic dipyramidal shape. These specimens are found in banded gypsum and marl from the Trias in a Keuper facies characteristic of the Cortijo Cañadas, in the N of the Montejícar municipal district. In the area there are some interesting ruins of plaster kilns.

RM1829   Graphite

Tres Hermanos mine, Pilotuerto, Tineo, Asturias, Spain

Nowadays, graphite specimens from this classic Asturian locality are very difficult to be found. These specimens show contiguous columns, with greasy luster and defined hexagonal forms. The crystal habit of natural graphite in most cases is determined by its highly anisotropic, layered structure. However, anomalous habits of graphite, determined not only by its structure, but also by the peculiarities of the growth environment, are frequently encountered.
