zoup Posted October 14, 2009 Share Posted October 14, 2009 (edited) Hi I was up to the Ambridge Pa. site today and I found a few rock formations that had a thin outer coal line with what looked to have a sulfuretting color. When I split the rock there were these little crystals. Does anyone know what mineral it is and how is it formed.

Auspex Posted October 15, 2009 Share Posted October 15, 2009 That's really wonderful! Must have been a surprise... Maybe there's some pyrite involved?

zoup Posted October 15, 2009 Author Share Posted October 15, 2009 (edited) That's really wonderful! Must have been a surprise... Maybe there's some pyrite involved? Hi Auspex. It was a suprise, It has a silver almost clear look to it like quarts, also its not inbeded in the rock, it seems to be a layer all its own. Paul. Also I found alot of this stuff up there today. Ozzy I can send you some if you like. Edited October 15, 2009 by zoup Link to comment Share on other sites More sharing options...
Shamalama Posted October 15, 2009 Share Posted October 15, 2009 does it fizz in vinegar or acid? They might be some Calcite or Selenite deposited between very thin layers. I'm not sure of minerals associated with Coal, lots of different stuff happening there due to metamorphic action and acidity. -Dave __________________________________________________ Geologists on the whole are inconsistent drivers.

texaswoodie Posted October 15, 2009 Share Posted October 15, 2009 Looks like Selenite. We have some here that is associated with coal. Link to comment Share on other sites More sharing options...
