New Members MadisonLynn Posted December 7, 2012 New Members Share Posted December 7, 2012 I found this rock in a pile of rocks laying around in Fort Hood, Texas. What could this be? I know nothing about rocks or anything really..But I have always been obsessed. I have a huge collection of rocks but I have never seen one like this...http://www.flickr.com/photos/madisonlynnerwin/ Link to comment Share on other sites More sharing options...
Herb Posted December 7, 2012 Share Posted December 7, 2012 Calcite? Does it fizz if you put vinegar on it?

stoll Posted December 7, 2012 Share Posted December 7, 2012 calcite / tiger eye just a guess. same me, i have a load of rocks but no clue what any are but they are different to just normal ordanary stones. the picture im showing, is a yellow orange stone hard cant scratch it and it got bits in it, and the green pictures are results as i pointed green laser into it. other picts from an ammonite that i accdently broke and this was inside. blue yellow and red speks of light sparkling. i dont know alot of rocks and minerals still learning. if any1 knows what they are please let me know. thanks Link to comment Share on other sites More sharing options...
itwasntme Posted December 7, 2012 Share Posted December 7, 2012 Stoll, I am completely new to all this, so don't take my word on it, but try looking up "ammolite" my understanding is its a natural occurance in some ammonites. (the sparkling you saw after accidentally breaking the ammonite) I have no clue on the first pics. Hope this may be of some help. Link to comment Share on other sites More sharing options...

CherylW Posted December 7, 2012 Share Posted December 7, 2012 It looks like calcite for sure, and the dark parts are possibly black tourmaline. Link to comment Share on other sites More sharing options...
FossilFisher Posted December 10, 2012 Share Posted December 10, 2012 I'm thinking calcite too. Try a black light on it, it should glow back if it is, although not gauranteed. Also the vinegar test is really good at proving it. Link to comment Share on other sites More sharing options...
