Rosell Minerales

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.

Size: 6.6 x 3.2 x 2.7 cm.
Main crystal: 10 x 9 mm.

Group of very sharp trapezohedral analcime crystals, good brilliance and with the usual transparency for the species. They are disposed in a cavity of the volcanic rock covered by calcite. Very interesting specimen from a poorly represented locality in collections.

A curiosity that I found aesthetic and mineralogically interesting. Usually the menilite opals are found in a marlstone matrix, but in this case we found it included in gypsum with clay inclusions. A Spanish curious specimen...
