Since some of you seemed to like these, I thought I would post a few more pretty rock photos with short descriptions. Most of these have the shiny dime as well.
I emailed these photos to myself from the lab computer using Gmail. As a result, my Gmail account was shut down for 2 hours due to suspicious activity. Apparently, sending many high-resolution photos of rocks to yourself is not normal activity. I’d argue that it is a normal activity for me… but I can see how it might be considered spam by some people…
I certainly find these rocks (and many others) beautiful. As the wonderful “First Aid Kit” song posted by Rebecca says, “It’s One Life, and It’s This Life, and It’s Beautiful.” For my one life, this life, I find rocks such as these beautiful. I find many rocks beautiful, but that’s just me. It’s not just rocks. We all can find beauty in one life, this life- be it a sunset, an orchid, a child, a kitten, or a stream of bubbles in beer– there is beauty in abundance everywhere.
Rock “50C” on the inside. Cut slabs reveal much about the inner (generally less-weathered and less-oxidized) portion of a rock. For many rocks, it is impossible to make an identification without breaking off a fresh surface or using a saw to cut a fresh surface.
Added for MarlowePI:
When I say that the peridotite has been altered, I mean that it has been changed from its original composition and form. Peridotite is an igneous rock, which means that it is formed from liquid magma. Initially, the crystals found in peridotite– mostly bright green olivine and green and yellow pyroxenes– are bright and sparkly. Over time, the crystals in peridotite both alter (change chemical composition) and weather (physically break down) as they interact with their environment- water, air, heat, etc.
Fresh peridotite looks like this:
Fresh peridotite contains very beautiful green olivines- this is where the gem peridot comes from. Note that the two above photos were stolen from the interwebs. I study how peridotite alters, so my samples never have fresh olivine. I am lucky if I find somewhat fresh pyroxene.
Not quite as pretty, are they? :-)
