Field trip to the central part of Krušné hory Mts. (Erzgebirge)

This two day field trip took place from 3th to 4th of June 2017 and was concipated to visit mainly Fe, Mn and fluorite deposits in the central part of Krušné hory Mts. (Erzgebirge) with some additional stops on other deposits.

First day:

DSCN4409

We started the excursion in town Horní Blatná. Here we visited vein of Marie Terezie and heap of Concordia adit . Minerals occurring there were mostly Mn ore – pyroluzite. We found also quartz in small crystals up to 3 mm. Then we moved to „Ametystová Halže“ near Horní Halže village. This site is old mining part of Měděnec district and there is a large number of surface exposure of old mining activity. We found mostly amethyst and quartz crystals, ordinarily in clusters up to 7 cm and the primary Fe ores like limonite and pyrite.

DSCN4424

After first part of the excursion we moved to rock formation called „Sphings“ near town Měděnec formed by very high pressure deformed „eyes-schist“ from Variscian orogeny processes.

DSCN4446From this place we could see landscape of Doupovské hory volcanic centre. Our another stop was at Mědník hill near town Měděnec. This small hill is the skarn body preparated by erosion in Quaternary and one of the most mined Fe and Cu deposit in early modern age. We ascended to the top of the hill around old skarn heaps and there was lecture about local mining from medieval to the end of 20th century.

Second day:

DSCN4502The weather condition did not allow us to see all three fluorite deposits in Krušné hory Mts. according to former plan, but only Hradiště fluorite deposit near Kadaň town and Kláštěrec nad Ohří town. This small deposit was mined for barite, fluorite and hematite. We found only fluorite and hematite samples. After that we moved to The Chateau at Klášterec nad Ohří town, where was also an exhibition of local minerals. We saw very nice samples of polished agates from Horní Halže village, Černý Potok vil., Ciboušov vil. and other sites.

 

After that we visited local spa area and we drank local hydrothermal water from the spring. P1270149This hydrothermal energy is caused by volcanic activity bound on Ohře rift and was formed mostly in Tertiary. Then we moved to quick visit of Ahníkov (former vil.) – site with minerals of weathering of laterites. We found specific minerals like white and purple chalcedone, green chryzotile and small crystals of quartz. After that we moved to our last site which was Lehnschafter adit in Mikulov town. Mikulov was mined mostly for Ag ores like Ag-rich galenite.

Field trip to the historical mining in Kutná hora and its surroundings

P1260520

First day:

Visiting of adit St. Jiří in Oselské district – Medieval adit St. Jiří is a part of the mining-historical exhibition of the Czech Museum of Silver. This adit was discovered in 1967 during a hydrogeological survey and the length of its accessible part is about 280 metres.
Quarry Práchovna – A new outdoor geological exposition was opened in August 2014 in the former quarry Práchovna. In this exposition are used a blocks of rocks from Kutná Hora area, Kolín and Chrudim with thematically structured panels.

P1260547The slag heaps – were deposited in the immediate vicinity of the silver smelter. The ironworks in the Vrchlice Valley were in operation from the 15th century until the end of the 18th century. This despite of the partialy flattened heaps, containing an estimated 400,000 tons of slag, are witnesses of the vast range of medieval metallurgical activity in the area.
The St. Antonín Paduánský – is one of the most important mineralogical sites of the Kutná Hora region. The work followed a vein with a high content of antimony and silver ores. In the adit and in the dump we can get to know not only with typical veined minerals, but also with some luck we find rare silver ores. Our findings: berthierite, kutnohorite, pyrite, cave pearls.
The site of the former RD Kutná Hora establishment – here is the Turkaňk mine, which draws the mined water treated in the built-up cleaner for user quality. A large basin in the southern part of the Turkaňk zone was created by the mines collapse in 1969. In the eastern wall of the basin is a gallery of an old mine about 100 m long. This old gallery belongs to the oldest phase of Kutná Hora mining.

P1260624

Old heaps after mining of ores in the village of Kaňk – This dumps are an interesting occurrence of rare arsenic minerals. For the last two years, heaps have been involved in many pitfalls because they have been exposed to erosion or by targeting of the collectors. Hopefully, due to the timely intervention of the experts which was made, there will be no complete disposal of the heaps, as was previously thought. Our Findings: bukovskite, kaňkite.

Second day:

P1260684Malešov – a magnetite rich rock deposit opened by deep mines. Our findings: magnetite, garnet, pyroxene, amphibole, prehnite, calcite, epidote.
Markovice – active amphibolite quarry near Čáslav. Known occurrences of alpine type minerals. Our Findings: prehnite, titanite, albite, calcite.
Kožlí near Ledeč nad Sázavou – a small fluorite deposit with a high content of quartz. Our findings: fluorite, quartz.

Fourteen Chapter members participated on this excursion led by Mgr. Jan Bubal.
