Extraordinarily Fantastic New Discover of Skeletal Halites in Poland (Pictures)

In late 2016 geologists working in Sieroszowice copper-halite mine, whereas go to one of many previous tunnels, found very wealthy and colourful halite mineralization. The tunnel was situated fairly removed from the lively areas of the mine so it was time-consuming and troublesome to succeed in. In the middle of a number of visits geologists have been capable of acquire a number of hundred uncommon inexperienced skeletal halite crystals in spectacular varieties.

Geology and Location

The Lubin space (SW Poland) is legendary for one of many world’s largest copper (sixth largest producer) and silver (2nd largest producer!) deposits. The deposit is called Legnica-Głogów Copper District (LGOM) mining kupferschiefer – copper shales. There are over 20,000 miners employed in three monumental mines. The typical depth of workings is about one thousand m (it varies from four hundred m to 1200 m). A number of years in the past, the whole size of tunnels reached over 10,000 km. All mines are operated by an enormous nationwide firm KGHM Polska Miedź.

Formation of the copper, silver and halite deposits mined on this space is related with deposition in a late Permian sedimentary basin. Presently half of what’s at present Europe was coated by comparatively shallow epicratonic sea generally known as Zechstein Sea. Fluctuations of its depth, resulted in a number of evaporitic occasions. Throughout these occasions, deposits of halite and black shale (wealthy in copper, silver and platinum group parts) have been shaped in cyclic sequences, generally known as cyclothemes. Crucial ore minerals happen as micro-grains and are seen solely beneath the microscope. Halite, in distinction to the ore minerals, types layers reaching as much as one hundred sixty m of thickness! Within the Sieroszowice mine each deposits – halite and kupferschiefer – are mined. Halite wealthy layers are situated about eighty m above the copper black shales.
