Classic locality

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: 5.6 x 3.7 x 2.8 cm.
Main crystal: 10 x 9 mm.

Fibrous aggregate of tremolite crystals, very brilliant and with an olive green colour. They are accompanied by prismatic crystals of darker green actinolite and orange calcite. Good size and representative for the locality and the species. The Manuel-Mercedes open pit is embedded in the granitic intrusions that were accompanied by contact metamorphism and gave rise to the formation of the skarn, with important deposits of magnetite.

Size: 8.5 x 7 x 5.2 cm.

Druse of very sharp baryte crystals showing developed and striated prismatic faces, truncated by pinacoids. The crystals are translucent, and color varies between colorless to yellowish. Excellent brilliance. Similar specimens were classified, many years ago, as hokutolite (a lead-rich baryte variety) but further analysis showed that there was only a minor lead content.

Size: 7.5 x 6 x 4.7 cm.
Main crystal: 6-7 mm.

Into a galena matrix vug we can see some anglesite crystals well defined, with brilliance and richly faceted. They show a good transparence and striated faces. They are accompanied by galena crystals those have grown on faces other small crystals of the same species. A sample from a great classic Spanish locality.

The label of this specimen reads "Sevilla". In the catalog of the Manchion collection it is mentioned that this piece of schorl-dravite was acquired to Dr. Joan Viñals, at the Granollers fair in 1988. For that reason, in the absence of more info, we will leave this wonderful Andalusian region as its origin. M. Calvo talks about tourmalines in pegmatites from the Los Ángeles mine, near El Castillo de las Guardas, in Seville.

Gray djurleite well defined crystals (largest group 9 mm) interpenetrated, showing octahedral forms, with triangular faces. On a matrix of copper sulphides. As usual of these specimens, they may actually correspond to phases of djurleite-chalcocite. We can consider the specimens of Las Cruces mine among the best worldwide. From the former Povill collection.

Size: 8.8 x 6.8 x 4.3 cm.
