At the gem festival in Herkimer NY, July, 2016, the discovery of crystal frost in the Herkimer Mining District, was announced. Here we will describe its major forms.
As of summer, 2016, we are processing photos and waiting for more public involvement. The crystal frost is a new discovery and there appears to be a range of forms it can take. The first slide shows its most common form. These have been found most often as inclusions inside quartz that is in contact with hydrocarbon. But they also occur FREE STANDING on a matrix of hydrocarbon and silica.
Due to several injuriesDr C has beenforced to put thisHerkimer diamondresearch on hold.Will return this winter(see discoveries page)
The importance of the crystal frost event is that it formed a base, over dolomite/oil filled rock, upon which the Herkimer diamonds then grew. Not all Herkimer diamonds grew attached this way, but many did. The crystal frost helps to explain how it is possible to grow quartz in an oil filled dolomite rock.
