Diamonds are interesting, but I have no desire to take them to the movies.

Interesting post here about “The facts about diamonds.” The author of the post mostly focuses on the cultural/social aspects of diamonds, and for the most part I agree with him. I’ve always found jewelry commercials in general irritating, and even more so the ones that dig up the rotting corpse of “diamonds are a girl’s ...

Using Geochemistry to find Kimberlites

I found this article pretty interesting: The GOPE 25 Kimberlite Discovery, Botswana, Predicated on Four Mg-Ilmenite Grains from Reconnaissance Soil Samples: A Case History Basically, some kimberlites were identified using indicator minerals that came from the soil above the pipes. One of the important indicator minerals was ilmenite (which I had in my own pet ...

A girl and her pet rock (4) 1

So I just realized that I owe a post for today. I spent my entire day working on my geology term paper, so I have nothing all that clever or interesting to say. So I guess instead of falling down on the job completely, I shall share the rough draft of my paper. Yay? Unfortunately ...

A girl and her pet rock (3)

Well, I did my photomicrographs of my thin section today, and I think they turned out really well! There’s some beautiful examples of what calcite looks like in thin section if nothing else. I’m still sad that all of my olivines have been altered by weathering, though; normal olivines are very bright and pretty. Altered, ...

A Girl and Her Pet Rock (2)

I went back to the rock lab on Monday to finish up my thin section. Which I should have picked up from the rock lab this morning as a matter of fact. Except that I forgot. You see, I had a brain once. Then I forgot it somewhere and I’ve been screwed ever since. Hopefully ...

A Girl and Her Pet Rock (1)

One of the cool things we’re doing for this field class is cutting a thin section of a rock that we picked up on one of the field trips. Chuck, our teacher, has been calling these rocks our “pet rocks.” I picked my pet rock up at the Green Mountain Kimberlite. And named it Bobby. ...

Backyard Geology: The Green Mountain Kimberlite

Unfortunately, I can’t provide very good directions to this one, and there’s a good reason for it. We drove up to Green Mountain (near Boulder, Colorado), got on one of the trails, and then at a random time just sort of bombed off into the underbrush. It involved going down and back up an extremely ...
