“The state of the Geoblogosphere” – Online publication with first scientific data about the Geoblogosphere

Lutz Geißler — Tue, 04 Oct 2011 16:37:20 +0000

Geonetzwerk.org recently published the complete results of the geoblog survey (2009). The authors Dr. Robert Huber (MARUM, Bremen), Callan Bentley (Northern Virginia Community College, USA) und Lutz Geißler outline the social and demographical makeup of the Geoblogosphere and provide an interesting insight into the motivation of the geobloggers. Study “The state of the Geoblogosphere – [...]

Workshop “The best way to transfer geoscientific knowledge to the public” at GeoMunich2011

Lutz Geißler — Mon, 02 May 2011 14:44:43 +0000

As a follow-up of the workshop at the GeoDarmstadt2010, where we learned about manifold experiences in geoscientific public work in the field, this time we intent to focus on the elaboration of a white paper helping to find the best way of practicing a target group-related transfer of geoscientific knowledge to the interested public. The [...]

Coleman Quartz Mine, Arkansas – fascinating quartz crystals

Lutz Geißler — Sat, 04 Dec 2010 19:56:25 +0000

A friend recommended a video showing impressive large quartz crystals. They were found in the Coleman Quartz Mine in Arksansas, USA. As far as I know these clear quartzes were formed by hydrothermal processes and are bound to large fault zones within Ordivician sandstones. Watch these amazing videos:

Book recommendation: Geochemistry of European Bottled Water

Lutz Geißler — Thu, 19 Aug 2010 07:00:42 +0000

“Geochemistry of European Bottled Water” is a forthcoming book of Borntraeger Science Publishers. Clemens Reimann and Manfred Birke (Eds.) summarize the data of a large research project during which a group of European geochemists investigated 1,785 bottled water samples from 38 different countries, 1,247 water sources at 884 locations. They detected about 70 elements and [...]

Keanu Reeves and geology?! – Celebrities and their geo-relatives

Lutz Geißler — Mon, 09 Aug 2010 18:01:15 +0000

A comment on Facebook gave me the idea to create a list of celebrities with parents, childs or other relatives who are connected with geosciences. Did you know that Keanu Reeves‘ father has been a geologist? Such a compilation is only realizable with the help of you. If you know a famous person (dead or [...]

9th Freiberg Short Course in Economic Geology: Magmatic Ni-Cu-PGE deposits

Lutz Geißler — Mon, 09 Aug 2010 07:00:13 +0000

The 9th Freiberg Short Course in Economic Geology will take place from 6th to 10th December and is dedicated to magmatic Ni-Cu-PGE deposits, their petrogenesis and exploration. The lectures will be given by Prof. Wolfgang Meier, Professor of Geology and Mineralogy at the University of Oulu in Finland since 2009. His research is focussed on [...]

Geological waterway: Fluid migration in hydrothermal systems

Lutz Geißler — Tue, 03 Aug 2010 07:00:37 +0000

Gold-bearing quartz veins related to the orogenic gold type are typically ribboned as known from my research area northern California. The ribbons there are formed by vein-parallel shear planes, dividing the quartz in decimeter to micrometer thick bands. Ore-bearing fluids intruded the shear planes several times. This multi-stage mineralization is verified by microscopic investigation of [...]
