November, 4th 2016 : News and Updates
Ore Microscopy : Light yellow sphalerite replaces zonar calcite and sandstone grains, Osterfeld colliery, Ruhrgebiet, Germany
The second half of 2016 brought some new interesting projects, such as a detailed survey on lead - zinc mineralization in the Ruhrgebiet, Northern Germany. While the Ruhrgebiet is famous for its coal mining industry, a number of little known, but economically important lead - zinc vein mineralisation are present in this area as well. During ore microcopy work we came across some truly aesthetic sections, such as the sphalerite replacement ore shown above.
We updated the Mining Newsletter section and you can now read and freely download these newsletters up to the 40th week of 2016. There are also two new publications available : A short field trip guide covering copper and gold mining in the Kitzbühel and Rauris / Gastein valleys in Northern Austria and a photo report about the truly breathtaking Turda Salt Mine in Western Romania, we visited in August of 2016.
View from below into the bell shaped Theresia salt chamber, Turda salt mine, Romania
Currently we are in the process to update our publications and add english summaries to all of them. So please feel free to check back often in the coming weeks for a lot of updated papers of ours.
July, 12th 2016 : Mid Year - Update
Hard to believe, but the first half of 2016 is already over ! Time for a short Mid Year - Update of our activities so far :
In the last months we had the opportunity to take a closer look into a huntite deposit in Western Turkey. Huntite is a little known carbonate mineral, which due to its extremely whiteness and light weight is used as a high quality flame retardant filler in plastics and rubbers. Luckliy I was also able to visit the famous thermal sinter terraces of Pammukkale once again, this time in rainy weather.

Other projects in the first half of 2016 included a desk top study about talc potential in Africa as well as looking for sphalerite (zinc sulphide) samples for detailed assaying in the Ruhr Area. For more information about huntite, talc and lead - zinc ores in the german Ruhrgebiet please feel free to contact us here.
April, 14th 2016 : BAUMA 2016 and Mining Newsletter
Its BAUMA 2016 time. Please find below some impressions from our visit to the largest building-,construction- and mining machinery fair in the world in Munich this week. Always a great experience and eye opener !

September, 30th 2015 - 1. Meggener Rohstofftage / Workshop PERC-Reporting
Sicilia shaft Meggen
The Meggen mine in the Sauerland / Central Germany was one of the most important European baryte & zinc mines until its closure in 1992. This year the mining geology tradition of Meggen was revived by the 1. Meggener Rohstofftage from September, 17th to September, 19th 2015. The symposium was held in the Sauerland - Pyramiden and was jointly organized by GEA / Sachtleben and Tracto-Technik under the patronage of BDG, the german professional organisation of geologists. During the first day a workshop was held on Best Practice PERC, NI43-101 and JORC reporting, while on the second day a number of presentations were given on current mineral exploration projects in Germany.
Best Practice Reporting Workshop Certificate
Meggen evenings were spent with leisure social gathering and ample exchange of experiences on the premises of the historic Sicilia shaft buidling, which is the main former hoisting shaft of the Meggen mine, see image above. On the morning of September, 19th there was a half day field trip with the opportunity to visit the Meggen Erbstollen = water adit with adjoining water beneficiation plant or a visit of innovative horizontal drilling systems of sponsor Tracto-Technik. Concluding the 1. Meggener Rohstoffrage was an excellent and well-visited event, which will be followed by the 2. Meggener Rohstofftage in September 2016. Many thanks and Glück Auf for the organisation committee ! More information on the 1. Meggener Rohstofftage can be found on the BDG homepagehere

December 19th, 2014 - We thank all our Friends, Collegues and Partners for your friendly Cooperation in 2014 and wish you all a Merry Christmas and a sucessful and blessed New Year 2015 !
November 22th, 2014 - Major Website Update
In the last days we have done a bit of work on this website : A bit of updating here : see references, a bit of streamlining there and a lot of translation into spanish language thanks to fellow geologist Matthias Jurgeit. Matthias, thank you !
November 14th, 2014 - Kimberlite Cake !
A few days ago I celebrated my birthday ! The wife of a befriended spanish geologist made me a very special present : a Kimberlite Cake, with embedded diamonds !
For more information about the cake and how to make it, please have a look at Lady Héloïse´s website at http://www.lacocinaromantica.com, where you can also find a lot more of lovely cakes. Buen Provecho !
October 29th, 2014 - New Publications and Presentations added :
About a month ago I gave a talk about the geology and mineral potential of Namibia in Bochum. You can find the online version of this presentation at our publication site or here and here. For shorter download times the large file has been split into two parts. Also added some material about giant olivine crystals in Seberged / Zabargad island in Egypt, giant salt cubes in the Merkers Mine, Thuringia , Germany and about equally giant vivianite crystals in Cameroon, all of which was originally written for the Giant Crystal Project back in 2005 - 2007. Enjoy the spectacular images !
October 20th, 2014 - Granites at Ploumanach, Brittany, France :
A few months ago we had the opportunity to visit some outstanding pillow lavas in Northern Cyprus (see below). This summer we were fortunate to see some extraordinary "pillow granites" in Brittany. The scientific term for these round structures, which are typical for granite weathering, is exfoliation. In german geology another perfectly fitting term is used "Wollsackverwitterung" which translates to "wool sack weathering". Indeed the granite often looks like wool sacks piled above each other.
While beautifully sculptured granites are not that rare, they are mostly found in inland areas far from the sea. Here we show some scenic examples from Ploumanach in Brittany. Enjoy !
April 2nd, 2014 - We present our new ECO-MINE Economic Mineral Database :
For almost 10 years we have compiled a massive database covering the whole spectrum of mineral commodities, metallic-, non-metallic and energy mineral potential as well as about individual mines and regional mining information. ECO-MINE Economic Mineral Database currently hosts about 100.000 full text searchable data files, giving you easy access to a wealth of relevant mining and mineral related information. We are now able to offer search services of our ECO-MINE Database to a broader audience.
Please have a look at our Publication Site to see a presentation of ECO-MINE.
March 11th, 2014 - New mineral and mining publications and maps online :
Two new english language publications online about the Namaqualand / South Africa mineral deposits, based on a somewhat "historic" field trip in this region back in 1988 "Resource Appraisal, Target Generation and Exploration Methodology within the Namaqua Metamorphic Province" as well as a photo - report about a much more recent due diligence / assessment of antimony deposits in "The Cam Pha Antimony Belt in Northern Vietnam". There is also a new map available covering "European Potash Mines / Producers and Development Projects 2014". As always, please have a look at our publication site to see and read these map and papers.
February 22th, 2014 - Spectacular Pillow Lavas from Northern Cyprus
Pillow Lavas are basaltic lavas, which have formed by submarine lava flows, which solidified in a very typical manner called “pillow structures” or simpler “pillow lavas”. While pillow lavas are a not so rare geological phenomen, most of the occurences are not really spectacular. However some weeks ago I had the opportunity to visit Northern Cyprus and came about a little known area around Balalankoy / Platanissos where there are virtually mountains of excellently developed pillow basalts in a text book like fashion! More, there is also a long fresh road cut running through this volcanic suite, exposing the whole geological sequence for about 2 kilometer length! Worth a visit and well worth some more geological research...there is even a gossan nearby indicating copper mineralisation. For more information please send us an email.
December 19th, 2013 - We thank all our friends, collegues and partners for your friendly cooperation in 2013 and wish you all a Merry Christmas and a sucessful and blessed New Year 2014 !
