“…Large plate specimens, with rhombic symmetry, were noticeable, mostly with a large number of voids filled with celestine. Such specimens were from 0.3 to 1 mm large and often occurred in twin forms and indicated a strong flattening in the direction of axis y (Strunz 1966), with strong elongation in the direction of axes x and z. The plate-shaped halite crystals most often grew out of the fine crystalline centres of terrigenous material, in the direction of halite mass, or otherwise created independent plate specimens, often overgrowing each other (Borkowska & Smulikowski 1973).…”

Pale brownish celestine-rich salt rocks were found near the Franciuszek Müller gallery, in the chambers of the 3rd level in the Wieliczka Salt Mine. The complex of rock salts subjected to exploration occurred within a large seam approximately 15 m thick. Detailed research revealed that the salt has the form of a block incorporated within the gray salts body and being similar to other blocks of green salts, well known in the upper part of the deposit. A characteristic petrographical feature of the pale brown rock salt owed to the presence of celestine (SrSO 4 ). That strontium mineral was re-examined, using X-ray powder data, and scanning microscope observations, with EDS analysis.The investigated rock salts exhibited a mineral association of halite (main component), anhydrite, celestine, calcite, gypsum, clay materials, iron compounds and a small amount of bitumen. In terrigenous sediments and the insoluble part of salt occurred higher content of strontium that in halite. Celestine crystals were observed in two forms: elongated platy crystals, forming fan-shaped aggregates and granular aggregates, strongly associated with anhydrite. On carbonate and sulphate strontium usually appearing as needle shaped aggregates of celestine. No barium minerals were observed.The development and paragenesis of celestine suggested a post-sedimentary origin of these rocks that ought to be connected with diagenetic processes. An important observation that confirmed that thesis was the transformation of fine crystalline anhydrite into platy crystals, recrystallization and primary accumulation of strontium, as a result of evaporation processes.Keywords: rock salt, Badenian, Wieliczka, strontium, celestine, geochemistry types of salts were observed mainly in the east section of the deposit. It was established at the early stage of studies that this kind of salt did not match the surrounding formations and displayed clearly diverse properties and chemical composition.The purpose of this paper was to collect all of the available data on the so-called strontium and barium salts and present the results of our new studies completed last year. The main assumptions of this study consisted in the verification of the old data and confirmation of previous hypotheses on the formation of the type of salt

“…El caso más conocido es el de la aerinita (del griego aer, azul cielo), especie definida en 1876 por Lasaulx utilizando una muestra procedente de España, sin precisar procedencia. Más tarde, en 1882, Vidal encontró el yacimiento cerca de Caserras, Huesca y desde entonces se consideró un mineral español aunque no aparecía en glosarios tan importantes como Strunz y Tennyson (1970) o Fleicher (1983 o aparecía como una mezcla de silicatos de Fe, Mg y Ca en Robert el al. (1974).…”

RESUMENSe estudian los 27 minerales descubiertos hasta el momento en España comparando estos logros con los conseguidos en otros países. Se clasifica a los minerales de acuerdo con la «Intemational Mineralogical Association» (IMA) en minerales G (grandfather), minerales A (approved) y minerales R (redefined), comentando algunas vicisitudes de su descubrimiento.Se describe el protocolo para solicitar a la «Commission on New Minerals and Mineral Names» (CNMMN) la aprobación de un nuevo mineral.Palabras clave: nuevos minerales, España, nuevas especies, historia, números IMA. ABSTRACTWe study the 27 minerals found in Spain up to now comparing these achievements to the ones of other countries. These minerals are classified into three types according to the «Intemational Mineralogical Association» (IMA), G (grandfather), A (approved) and R (redefined), including the vicissitudes of every finding.It is also described the protocol used to pursue a new approval to the «Commission on New Minerals and Mineral Names» (CNMMN).
