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:


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.


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.


Eight Chapter members paticipated on this excurstion led by Bc. Jakub Mysliveček.

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


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.


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.

Then we’ll summarize our activities of the last year and then discuss possible events for the upcoming year.

Student membership fee stays 10 EUR or you can pay its equivalent in CZK (260 CZK).

New members are very welcome!

We look forward to meeting you!

Tertiary deposits of the Krušné hory Mts. (Erzgebirge)

The last field trip at 2016 (12-13th November) was organized to Tertiary deposits of the Krušné hory Mts. (Erzgebirge).

Starosedelské series of strata (quarry Erika)

Erika quarry

First day was in schedule visit of locality Valeč with nice samples of hyalite in pyroclastics and tuffs of Doupovské hory Mts. Then we moved to visit Sokolov brown coal basin, where we’ve seen active quarry Družba, ongoing recultivation on quarry Medard-Libník and sand quarry Erika with important sedimentary profile of Starosedelské series of strata. On the way to Boží dar village, where we slept, we stopped at the heap of abandoned copper mine Helena near Tisová (Kraslice).



Second day we moved more on the northeast to visit active phonolite quarry Mariánská skála in Ustí nad Labem city with nice samples of zeolites (natrolite) and then looked at the pseudokarst fluorite cave on the Děčínský Sněžník Mt. exposed thanks to fluorite mining.

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

Field trip to Central Slovakia Neogene Volcanic Field

Traditionally our Chapter organizes autumn field trips to abroad. This time it was to neogene volcanic field in Central Slovakia, in area of Banská Štiavnica and Banská Bystrica. Field trip took place from 7th to 10th October 2016.



First day we visited quarry near Lehotka pod Brehmi. We have seen here a lot of perlite and some obsidian peaces, volcanic glass of neogene age.

Other day we focused on tertiary Fe, Cu mineralization in meta-greywackes and meta-sandstones of permian age in Ľubietová – Podlipa area. Here we visited heaps of mines Johan, Reiner and Dolní Ladislav with nice samples of pseudomalachite and libethenite. Then we moved to Špania Dolina, famous by its historical mining of Fe and Cu ores from deposit Piesky which is also formed by permian meta-sediments affected by tertiary volcanic processes with mesozoic carbonate rocks around. We were collecting here some samples of azurite and malachite.

Sfalerite in quartz vein

Third day our interest was moved to locality Farbiště near Ponická Lehôtka where we can find triassic carbonates penetrated by triassic andezites and ryolites. From primary tennantite and chalkopyrite grew up big amount of secondary minerals. Next we looked at Banská Belá where we were looking for some nice quartz varieties from mesozoic quartzites.

At the last day of excursion we divided into two groups. First group visited active gold mine Rozália and second group visited the heap of this mine. Deposit is evolved in volcanics of Štiavnica stratovolcano (mainly andesites). Before gold there was mined Cu, Pb and Zn. Gold with base metal mineralization is contained in brecciated and/or banded quartz veins.

DSCN167423 members of our Chapter participated on this excursion which was led by Chapter president Ondřej Krátký.

The 8th Siberian Early Career GeoScientists Conference

In June 2016, five members of our SGA chapter took part in DSC01727The 8th Siberian Early Career GeoScientists Conference in Novosibirsk, Russia. We have presented there our work and we all have participated in field trips to Altai mountains. It was great opportunity for us to discuss our thesis, observe work in different institutions and also learn geology in the field.

This trip would not be possible without the financial support of the SGA organization.

Gold from the Jílové u Prahy ore district (Central Bohemian Masiff)

On the 21st of May SGA Student Chapter Prague organized excursion to the historical gold mine located within the gold-bearing district Jílové Belt (located near Prague). We have visited historical adit Václav which led us directly to the Pepř mine. In this adit we had a chance to observe quartz stockworks with a little amounts of gold. During the mine visit we were able to collect some samples of gold-bearing quartz and also samples of scheelite mineralization from the Tobola vein. Some lucky students have even samples with small flakes of gold.

After the mine visit we have spent some time at the Museum of gold located at the city Jílové u Prahy.
Whole excursion was led by Dr. Pavel Škácha.


Excursion for the SGA Baltic Chapter (Bohemian Massif)

At the end of April, students from the SGA Student Chapter Prague prepared excursion to the Bohemian Massif for students from the SGA Baltic Chapter. During this trip, we had a chance to visit Mokrsko gold deposit located at the Jílové belt, former silver/uranium mine Svornost at Jáchymov city and several localities of greisen and skarn mineralization at the Erzgebirge Mts. This four-day field trip was a great opportunity to exchange ideas and make connections between our two SGA Student Chapters.
