Links of the Month - I

I decided to share original topics month by month. I usually keen on metamorphic petrology because of my study area- but not much can be found in blogsphere about metamorphism-. So the good ones:


General Geology

Signs of Primitive Mantle From Canadian Gneiss Dated 4.28 BA http://geology.about.com/b/2010/08/11/signs-of-primitiv-mantle.htm

and paper about this topic from Nature :: http://www.nature.com/nature/journal/v466/n7308/full/nature09287.html

Structural Geology / Microtectonics

Mountain Beltway's Callan Bentley talks about Purgatory Conglomerate with good photos and sketches- excellent blog by the way (especially for structural geologists )

And Bently's M.Sc. thesis, you can download it HERE::

Paleontology

A 48-million-year-old fossilised leaf has revealed the oldest known evidence of a macabre part of nature -- parasites taking control of their hosts to turn them into zombies.
