More than 90 million years ago, when the land mass of Pangaea began separating into the continents we now call South America and Africa, the earth may have produced a lucrative farewell gift: huge oil and gas deposits along both coastlines where they had previously been joined. Now, Angus McCoss, exploration director and chief geologist at Tullow Oil, which in 2007 discovered one of the biggest oil finds of recent years off the coast of West Africa, is betting more than $100 million that a similar bonanza awaits off South America's eastern shore.

In a gold mine in South Africa an international team of scientists has discovered water that is two billion years old. The find is described in the journal Chemical Geology.

Hi - I am new to this site, but today saw a fossil that I had not seen before, and wondered if anyone could tell me what it is.

I should have photographed something with it for scale, but the width was 75mm which would make the length about 300mm.

The shape was 4 parallel convex ridges, with narrow grooves between, but the overall was not curved, but flat.

Many thanks for any help

I was vacationing on the west coast of Panama and found this bowling ball size of a rock on the beach. The rock has been cracked open and appears to have contain small eggs. Can anyone help me identify it?

What are mantle plumes? why do they  exist? what are the theories?

I am a 3rd year student of applied geophysics( 5 year program) at  Indian school of mines, dhanbad(India). I have interests in doing an industrial intern in UK or Europe during summer 2011(may- august). I was wondering if anyone could let me know of the various opportunity in this field.

 Possibly the worst kept blog in the world?

If anyone can help identify this rock formation please leave a comment, Thanks!

Hi all

Im a beginner, I am heading up to the pentlands in the coming week - along the southern flank. I am wondering if anyone can provide me with details on the sedimentary and igneous rocks to look out for in these areas - i have a reference book ....keep it basic....

I am a huge fan of jade. For the last 6 months I have been gathering information and photos for my new website which is solely dedicated to my favorite stone. I just wrote my first article for this site about the colors of jade.

My new site is Jade Hunt. I have been working on it virtually non-stop so I hope you like it. I will be adding much more content as time goes along and I will be sure to update you all on it.
