Sorry it took so long to get back with better pictures... I've been having trouble getting as close up as I wanted but I think I've go some that illustrate my points. If nothing else this thread has given me an appreciation for the great photography that I see all the time on this forum and the idea that I need a better camera.
I am more convinced the material is chert, it is riddled with crystal occlusions, fractures concoidally and seems to meet the rest of the charataristic associated with it.
