RM2189   Epidote and quartz

Los Serranos quarry, Fondó dels Frares, Albatera, Alacant, Valencia, Spain

Very aesthetic group of deep green epidote fan-shaped aggregates on matrix. Epidotes have a good luster and intense green colour. There are some gemmy quartz crystals emerging from the epidote. The original label we will send to the buyer indicates that those crystals are clinozoisite, but recent studies show that all the analyzed specimens are epidote (Calvo, M., Subías, I. (2017): Epidote (not clinozoisite) and andradite garnet from Los Serranos quarry, Cabezo Negro, Albatera, Alicante. Mineral Up, 4:44-47).

 


Size: 6.8 x 6.2 x 4.3 cm.

RM2185   Aragonite

La Pesquera, Cuenca, Castilla-La Mancha, Spain

Many specimens of aragonite are seen, as "pinecone" shape, also isolated, but this specimen has an "I don't know what" that makes it different for me. An elliptical "pinecone" of prismatic, divergent aragonite crystals, which are grouped around a central axis, with more developed crystals. Different and very aesthetic. A classic from Spanish mineralogy.

RM2183   Hydromagnesite

Àngel quarry, Montseny massif, Gualba, Barcelona, Catalunya, Spain

Hydromagnesite specimens from "Pedreres de l'Àngel" (Angel quarries), in Gualba (Barcelona), are a classic for the Catalan mineralogy. In this specimen we can observe some aggregates formed by radiated crystals, some of them of good size (more than 2 cm.), others smaller (up to 8 mm), very brilliant. Nowadays impossible to be found... This mines are a skarn due to contact metamorphism of Hercynian granodiorite and biotite granite into Cambrian marbles.

RM2194   Scapolite (Meionite), magnetite, epidote and actinolite

Burguillos del Cerro, Badajoz, Extremadura, Spain

Aggregates of prismatic crystals of meionite, with cross-linked and parallel growths. It is arranged in a matrix with octahedral magnetite crystals, green epidote and actinolite fibers. Joan Viñals indicated on the label of this specimen (we will send to the buyer) meionite, although specimens such as marialite are described in the area. The marialite-meionite series refers to the proportion of Na and Ca, both of the escapolite group. "Probably from the La Herrería mine where it usually appears in magnetite vugs as acicular and radial aggregates of tetragonal prisms, sometimes centimetric, whitish to transparent" (Mti-Blog).
