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.

This first Fossil was found in a quarry in Tennessee, USA.  The rock is limestone of ordivician age.

The Second was also found in Tennessee, USA within a soil matrix, probably of the Mississipian age.

What is this pattern on ground of the ocean 200 - 300 miles west of canarian islands? I saw it today on google maps. Any ideas?

Two hundred million years ago, Washington was two large islands, bits of continent on the move westward, eventually bumping up against the North American continent and calling it home. Even with their new fixed address, the shifting continues; the more extreme movement has subsided laterally and continues vertically. The upthrusting of plates continues to move our mountain ranges skyward – the path of least resistance.
