A nice material, a bit of almost pure feldspar, from the "pink" granite we have around here. It is actually a single feldspar crystal. I found three broken bases on Ram Island today of different materials. This was the nicest.
(Sorry about the background blues lesson)
I'm not certain that this is granite or feldspar - it's too translucent. It may be a very fine-grained quartzite. This material sometimes interbeds with granite - at least in Westboro.
ReplyDeleteA Google search for "feldspar crystal" shows a few examples. They vary from clear to opaque. For example "orthoclase feldspar" and "K-feldspar" are close matches and the latter is a component of the granite common in this area.
