Volcanic Ejecta

Volcano Ejecta

I was initially drawn to this rock by the folded and distorted lines around the edges.  As I looked at it closer and rotated it in the light I saw that it might be a geode.  The crystals are at the far left in the dark place.  I feel sure that the distortion of the lines was caused my heat and pressure.  The yellowish center may be lava.  That is why I think it was ejected from a volcano

As I looked closer, I saw the granularity in the "lava."  And my attention was drawn to that dark area with crystals.

These crystals may not be diamonds but a diamond is one crystal which is ejected from a volcano.

Diamonds

Diamond

 

 

There, I have said it!  I think these are diamonds.  This is the rock that I showed you yesterday.  It came from a volcano.

I saw "How the Earth was Made"  last night.  It mentioned diamonds as being formed 100 million years ago while the dinosaurs walked the earth.  They discussed a mine in Kimberley, South Africa.  Diamonds are associated with the volcanic rock Kimberlite.  They said that the diamonds were formed 100 miles below the Earth's surface where there is intense heat and pressure.  The volcanic eruption which ejected them was a super eruption.  They are mined in a kimberlite pipe which was the route of the volcano eruption.

As I read about diamonds, I learned that the way to identify them is to use the Mohs scale.  It is a scale of hardness for minerals.  Diamonds are the hardest of all minerals at ten,10.  That means they will scratch any other mineral including corundum which is nine, 9.  I happen to have a test kit which includes samples of the various minerals for testing the hardness of unknown samples.

These are extremely small crystals.  I don't know if I want to remove them and if I did, I doubt that I could hold them to try to scratch corundum.

The diamond is said to have a white streak.  That means it will leave a white stream on unglazed white pottery when scratched across it.  My test kit also includes white pottery.

Breccia with Crystals

Breccia with Crystals

I have been wondering about this rock lately.  I started by looking at the white spot on the far left.  I noticed crystals in it.  Then I rotated the rock to this view and saw more crystals.

Lava Like Rock

I titled this one "Lava Like Rock" because of the granularity of the surrounding base rock.  The granularity along with the color made me think of Lava.  

I decided that the best way to show the crystals was to rotate it in a video.  Some of the sides are not nearly as interesting as these two sides but it gives you a complete idea of this rock.

View the video.  It is at the bottom of the page.

Geode

Geode

I have been photographing deformed rock lately as you have probably noticed.  This one was more interesting because it was also a geode.

Geode

As you will read in days to come, this rock also may be ejecta from a volcano.  It has an interesting mix of crystals and folding.  Both could be caused by lots of heat and forces.

Sometimes I think that the best way to share the rock in its entirety, or nearly so, is to rotate it in a video.  This is one of those.  Take a look at this video.  It is at the bottom of the page.

Smoke House Breakfast

Smoke House Breakfast

I have come to like Cracker Barrel Restaurant more than I used to because they have no MSG in any of their foods.  I don't get there very often but when I do, I like this breakfast.  It is a big one and I usually don't have to eat lunch after eating it.  Notice that the side of toast is for dipping the eggs.  The biscuits are for dipping the gravy.  

Thanks to Chris, Tammy, Hannah and Nathan I have been there more lately.  Also, thanks to Chad, Megan, Lucas and Loudon I had this particular breakfast.  

I have tried to photograph the breakfast previously unsuccessfully.  It seems that my HTC Incredible has focus issues.  I have been using the Camera 360 Ultimate app.  I should try the camera app that came with the phone before I quit.  This particular shot is better than most I have done but still not critically sharp.  I just don't want to stand on my chair to make the shot in the restaurant.

Deformed Rock

Deformed Rock

This is another of the rocks I found in the bucket.  I have been enthralled with it!  I even made a background for it of clouds.  Carol did not like it so I deferred to her judgement and did not save it.  I would like to know what you think about the concept.  This is a scan of the print that I made to show her.  It has a printer flaw in it but I think that you can get the idea.

Deformed Rock

I really like geology, and when I look at it, I see a mountain, a high mountain top.

Deformed Rock, The Other Side

This is the other major side of the same rock.  I love the shapes of the folds and bends.  I like to imagine what heat and forces might have shaped this beautiful object!

Intimate Landscape Reprise

Intimate Landscape

Congratulations to Linda Fugate.  She correctly identified the flaw as a purple lens flare created by the sun hitting my lens.  I did not see it until I processed the image at home.  I did not fix it because I thought that it would be too tedious to do so with the cloning tool.  

This morning I tried a fix advocated by Tim Grey, "Ask Tim Grey eNewsletter."  It was in his January 11, 2012 news letter.  You can go the his website to see the fix.  He will be glad to send the newsletter to you free if you are interested.  It was a very easy fix to apply and I shall remember to use it henceforth.  

Linda, if you care to, send me your mailing address and I will mail you a 5x7 print of the above image.  Thanks again for your feedback.

Back to Tim for a moment, I own several of Tim's books and it was from him that I learned my workflow.  I still think that it is a good workflow.  Tim now sells ebooks, and DVD's giving instruction.  He also travels around the world doing teaching sessions.  He has just heading to Austria.
