Dear colleagues,

As we all know, a devastating earthquake struck Haiti on the 12th of January. Thousands are dead and many are seriously injured. Please do whatever you can do today to help thousands of people in desperate need.

I am posting the link for the British Red Cross to make things easy..

https://www.redcross.org.uk/emergencysite/campaign.aspx?id=88917

 

If you are not a fan of Red Cross, a simple Google search will list many other charities worldwide.

Many of us might have already donated for this cause.

 

My apologies if you are not interested.

 

Best regards,

 

Shan


Please, help and contribute.

There is a few websites about structural geology that I visit once a week or more often. I would like to start a series of articles for briefly presenting them.

The first of this sites is "Structural Geology Techniques", in charge of Steven Dutch, professor of the University of Wisconsin. (http://www.uwgb.edu/dutchs/structge/labman.htm).

In the website of Dutch, a neat and organised page, you can find many examples and diagrams explaining a good range of geometric problems related with structural geology. There are from basic level problems (e.g., calculatina fold axis given the limbs of the structure) to not so fundamental problems (e.g., how to construct a down-plunge cross section).

As Dutch explaines in his homepage (http://www.uwgb.edu/dutchs/index.html), he does not like fancy graphics, and his website is an example of efficient diagrams, which isn't always the same as beautiful. However, they are clear and functional.

Visit the place if you didn't know it yet. You will be surprise with how many things you have forgotten of structural geology and geometry :-).

Carl Stevenson has released the programme for the TSG meeting in Birmingham this week. If you are attending, we’ll meet up there. If you aren’t… well, that is what you are missing!

(*student presentation)

For the first post of the year, I would like to include a link to an interesting map containing the major terranes of Europe, as it has been compiled by Martin S. Oczlon.

http://www.geobib.uni-hd.de/terranemap/index.html

Martin has used more than 2600 references for this outstanding work, and you will appreciate that when you will see the detailed mapping labour.

From the website of the terrane map of Europe:

WHAT CAN THIS MAP TELL YOU?

The aim of this map is to provide a view on the growth of Europe throughout its billions of years of evolution, applying a self-explanatory colour scheme. It is designed to allow also readers without much background on the geology of Europe to access the basic concepts on the assembly and accretionary history of the continent. At the same time, it provides in-depth information and key arguments for the various assignments.

Every part of the European crust with the same provenance, accreted at the same time or in one diachronous event, is given the same colour. Following Late Palaeozoic accretion of Gondwana-derived terranes, almost all of the crust that currently makes Europe was already assembled by ca. 280 million years. Therefore, terrane-description focuses mainly on their Palaeozoic and older pre-/syn-accretionary evolution. The younger sutures and ophiolite belts of southern Europe are the result of Meso-Cainozoic opening and closure of small oceanic basins within the previously accreted crust. These sutures are shown with a line-framework that outlines the boundaries of the major Alpine tectonic units.

For a better understanding of terrane-provenance, palaeogeographic reconstructions of Earth at 543, 444, 375, 299, and 195 million years are shown on the right-hand side of the map. Colours of the various palaeo-continents and terranes are the same as on the Terrane Map, allowing easy recognition of the past position of continental fragments that now form part of Europe.

And, before I forget it...

Happy 2010!!
