This could really help you.

While working on a lab assignment in the basement of Krebs, I became very frustrated with the lack of organization that exists in the collection of books we have.  The literature is never in the same spot (which I am partially responsible for) and the books themselves seem to have little order about them.  Now, [...]

     I was looking for interesting blog articles and came across the a piece of the puzzle as to the origin of petrology.
   Scandinavian and British petrologists initiated a new international journey that brought the attention of petrology to many.  The whole range of subjects that come under a liberal definition of petrology were to  be published in the journal.  The [...]

The Geology of Crater Lake National Park, Oregon With a reconnaissance of the Cascade Range southward to Mount Shasta

     It wouldve been nice to see Crater Lake in October while on the national GSA meeting, but unfortunetly our group didnt get a chance to go. Instead this article will have to quench my thirst for petrologic knowledge of Crater Lake

Geochemical Evolution of Paleoproterozoic Volcanic and Plutonic Rocks from the Omai Area, Guyana, South America: Implications for Tectonic History and Source Regions

I was searching through Google online books and came across this interesting article. Outside of Georgetown near the Omai-Potaro Mariaba region, the Bartica formation  consists of leucocratic biotitegneisses, amphibolitic gneisses and course-grained horneblende-biotite gneisses, representing high-grade equivilents of the overlying low-grade greenstone belts. 
The petrology of this region is interesting and helps me understand more about [...]

Variation in amphibole composition from the Andean Intrusive Suite across the Antartic Peninsula

I read a good article about the geology of the antarctic peninsula and the facts discovered surrounding the mesozoic-cenezoic subduction of the pacific ocean floor.  The rocks found are similar to the Andean rocks of south america, which contain calcareous-alkaline remnants of now fragmented western margin of Gondwana extending from south america to the antarctic [...]

Ol Doinyo Lengai Volcano – Eruption Effects

Ol Doinyo Langai is a volcano in Tanzania that erupts with natrocarbonatite lava, which is rich in calcium, sodium, and potassium, and low in silica.  Because this volcano is low in silica the lava is cool.  It alternates between effusive eruptions and explosive eruptions that build large cinder and ash cones.
For the effusive erutpions, the [...]

Finding diamonds in Wyoming and Colorado

In Colorado and Wyoming Diamonds have been found in 40 known diamond containing kimberlite pipes. Diamonds are very rare because the conditions suitable for their formation are also rare. The kimberlite pipes are vertical columns that were squeezed up from great depths(over 150 km deep) within the mantle, and these kimberlites have been deeply eroded (possibly 2000- [...]
