squali Posted March 21, 2012 Share Posted March 21, 2012 Thought I'd post a couple of pics of a 'Vivianite bloom' Not sure that is the correct terminology. The formation is a late cretaceous clay in New jersey with completely crushed shell fragments. Unfortunately no fossils are able to be extracted as the shell material is the same consistency as the clay. It's hard to remember why you drained the swamp when your surrounded by alligators.

Vordigern Posted March 21, 2012 Share Posted March 21, 2012 wow thats the most vivianite Ive seen in one spot in any of my NJ Cretaceous hunts Link to comment Share on other sites More sharing options...
squali Posted March 22, 2012 Author Share Posted March 22, 2012 wow thats the most vivianite Ive seen in one spot in any of my NJ Cretaceous hunts Mike I thought the same thing. The cobalt blue color stands out like a sore thumb. Wish it had something in it but it was worth my time to see it BTW. it should be the Mt Laurel formation It's hard to remember why you drained the swamp when your surrounded by alligators.

Ramo Posted March 22, 2012 Share Posted March 22, 2012 Darn, I was hoping to see a "vegamite sandwich" when I clicked on this. I guess South Jersey doesn't count as "a land down under".

lordpiney Posted March 22, 2012 Share Posted March 22, 2012 were there any Vivianite crystal clusters in that Jeff? i have a few from Inversand that are quite lovely. Ramo...YUCK! Link to comment Share on other sites More sharing options...
squali Posted March 22, 2012 Author Share Posted March 22, 2012 [High Iron content attachment=143031:P1000457.JPG]unfortunately no crystals in the macro sense. There were some about salt grain size but they had the hardness of finger paint. It's hard to remember why you drained the swamp when your surrounded by alligators.

steelhead9 Posted March 22, 2012 Share Posted March 22, 2012 Thought you might like seeing this mammoth tusk that mineralized with a high vivianite content. Before prepping, the whole tusk was covered with the blue powder you see in the second photo. This powder rubbed off on your finger like paint pigment.

squali Posted March 22, 2012 Author Share Posted March 22, 2012 Steelhead9 Wow beautiful tusk!! Siberia can't be all that bad Thanks for posting it. I have seen some bacculites mineralized with vivianite where the vivianite was stable. But I haven't found any yet. I do have a nice Squalicorax tooth that is steel blue from vivianite I'll try to post it later. Ramo, Some of us in South Jersey feel we are in the land down under It's hard to remember why you drained the swamp when your surrounded by alligators.
