Why are minerals mined as ores

The formation of ore and mineral deposits in the Harz Mountains

The many ups and downs of the mountain range in the course of its history created many fractures and cavities in the rock. Mineral
cal solutions circulate. The still hot rock heated up these mineral solutions in its cooling phase and they could rise in the crevices and cavities, cool down slowly and deposit the ores and minerals carried along. The largest warehouse
was the place
"Rammelsberg" near Goslar. Ores were sold here for over 1000 years.
Germany's largest existing iron ore deposit is in the
"Buechenberg Pit" at Elbingerode.But not all metals that were mined in or on the edge of the Harz for many centuries were created this way.
"Copper slate" is not one of them. It is a blackish, bituminous marl
slate, which comes from the oldest digested sludge formation on the bottom of the "Zechstein Sea". The largest occurrence was in the "Mansfelder Land". Evidence of this is still provided by that
"Röhrigschacht visitor mine" in Wettelrode. Iron ore and then pyrites were mined between Hüttenrode, Rübeland and Elbingerode for many centuries. At first in the "Großer Graben" above ground. Then the deposit was followed underground. In the last decades only pyrite was mined. From the beginning of the 90s of the 20th century the mine was accessible as a visitor mine "Drei Kronen und Ehrt" - until 2015. Iron ore mining ended at the end of the 60s of the 20th century.
In order to document the entire mining tradition of this area in words and pictures, the "Bergverein zu Hüttenrode eV" great effort expended. Books were created
which are understandable even for laypeople interested in mining. You can get the books directly from the
"Bergverein zu Hüttenrode" Respectively.The huge gypsum and limestone deposits emerged when our area was covered with a huge tropical sea and its coral banks. By training
washes resulted in huge cavities in some limestone formations, which today
chermagneten are. Who hasn't heard of the
"Rübeland stalactite caves" belongs?Limestone mining also leaves traces that are worth seeing in the landscape. As the "Blue Lake" at Rübeland proves. It is filled with water and depending on the water level, its color can vary from blue to green. On the "Bückeberg" near Gernrode the overturned layers of the mussel
to see lime. This happened when the northern Harz border was erected.
The Harz also had large deposits of fluorspar. A witness that can be walked on is the
"Glasebach Pit" in Straßberg. Other deposits also emerged in the distant past. They are organic in nature. We have brown and hard coal deposits around the Harz region. The coal mine
fours weren't big and weren't of much quality either, but they had to be
industry. At "Ilefeld" it was
"Rabensteiner Stollen" in dismantling. Today a visitor mine right next to the "Netzkater" station of the "Harzer Schmalspurbahn". Quedlinburg had a small area under the "Alte Burg" and the area of ​​Opperode was at the "Forsthaus Kohlenschacht".
