Found this on a large scale mine overburden dump a few years ago & am trying to identify it. After a bit of research it seems to be quartz with chlorite intrusion but I could be wrong. The crystals are very small, around the size of a match & the matrix seems to be sandstone. This is the only sample I could find, it could have come from an area over several square kilometers in size.
Hopefully some of the forum members might know what it is.
