The Dynamic Interaction of Quartz Bearing Solutions with Hydrocarbon Bearing Solution - Changes at the Boundary
There is considerable evidence that hydrocarbons were present when the various types of quartz crystals were growing in the Herkimer Mining District.  On this web page the focus is on microscope photography of features seen at the boundary between quartz and hydrocarbon.

Microscope Evidence
When a Herkimer diamond grows it can grow in direct contact with hydrocarbons. On the page which described large form changes (click previous button below) a series of photos presented changes in the overall crystal form, in response to adjacent hydrocarbons. On this web page the focus is on microscopic changes at his contact. Photographing such changes inside a Herkimer diamond is a difficult task. It is most important to have a clear view to an obvious quartz - hydrocarbon boundary, so it can be photographed.
This evidence, and the stunning photography, will be presented at the July, 2016, talk on “How Herkimer Diamonds Were Made”. Talk will be in Herkimer NY - at the High School.
