Mykkhul97 Posted May 25, 2020 Share Posted May 25, 2020 I am not sure of the type of rock these are. Marble of the white rock? Thank you for any info Link to comment Share on other sites More sharing options...
Darbi Posted May 25, 2020 Share Posted May 25, 2020 Not 100% sure: the first one I think is jasper and the second I think is white marble. Link to comment Share on other sites More sharing options...
ynot Posted May 25, 2020 Share Posted May 25, 2020 Hard to say without better pictures and more information on the pieces. Location they are from, hardnesses (different areas of the pieces may have different hardness), specific gravity, reaction to vinegar (acids). Second one could be marble. Both are cut and polished, and could be man made rock imitations. Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough."

Abyss Posted May 29, 2020 Share Posted May 29, 2020 I'm going with RainForest Jasper (Rhyolite) & Howlite - since Howlite is more commonly used & sold for sculpting items vs white marble. Link to comment Share on other sites More sharing options...

Yes, Rainforest Jasper is the word I was trying to remember! Thanks! Link to comment Share on other sites More sharing options...
Paleome Posted July 10, 2020 Share Posted July 10, 2020 On the top specimen, you may have something which includes shiny flakes of mica, muscovite ( if clear, silvery/gold) or biotite ( if black). Link to comment Share on other sites More sharing options...

DPS Ammonite Posted July 10, 2020 Share Posted July 10, 2020 (edited) Confirmed Llanite, porphyritic hypabyssal rhyolite with pinkish k-feldspar and included blue quartz in felsic matrix from Llano County in Texas. Ignore Spanish pronunciation; it is called “lawn-ite”. http://historyoftheearthcalendar.blogspot.com/2019/05/the-llanite-dike.html?m=1 https://www.mindat.org/gallery.php?loc=223196&pco=1 We need an acid test and hardness test to better ID the white wand. Edited July 10, 2020 by DPS Ammonite My goal is to leave no stone or fossil unturned. See my Arizona Paleontology Guide link The best single resource for Arizona paleontology anywhere.

Paleome Posted July 10, 2020 Share Posted July 10, 2020 I defer to your ID, very interesting. Alot of these photos aren't very good, and I thought I saw what could be flakes of mica. Link to comment Share on other sites More sharing options...
