Dawsonite

Dawsonite and Quartzite

The sample was labeled "Dawsonite"  I didn't know what Dawsonite is so I assumed it to be the starlike structur.  I worked and worked to get it where I wanted it in the frame.  I took print to the local rock, gem and mineral show to ask someone.  The response was  that the needles are Dawsonite and the starlike structure is calcite.

The reason I worked so hard to get the above and below shots is because the DOF is so thin and you can't see exactly what you will get until it is finished.

The above samples came from Francon Quarry, Montreal, Quebec, Canada.  The bottom one is at almost 18X.  Top one is ~10X where as the middle one is a little over 11X.

This has been one of my favorite rocks since 2010.  I usually walked the stream at the nature center when wild life was inactive, usually starting in December.  I picked this up in 2010, brought it home and threw it into the tumbler.  It went the first week and then as I was changing the grit, I decided to keep it out because I liked its looks just as you see it.

It's a loose end for me because I can not find it.  I want to test its hardness.  I have asked mindat.org to help me identify it and they have asked.

This is a panorama and I have loved the image for a long time.  The actual rock is about 1.5 inches horizontally,  When I made this as a print, I recognized something was wrong but I did not know what.  Recently, I was cleaning out the basement and found the canvas print I made.  I set it out and looked at it while I worked.  I decided it was just floating in the frame with no anchor so I added the shadows you can see above.  I had printed on the white canvas and stretched it.  Now, I wish to reprint it with the blue background but I do not have enough ink so I will leave it as is.  My friend, Paul the painter, came by and added the drop shadows with a felt tipped marker.  I am too shaky to do such a thing.

I may have given it to a visiting grandchild because they like rocks too.  I have asked them to look for it but no one seems to recognize it.

I hope you enjoy looking at it.
