Well as you’ve probably gathered by the above picture, I’ve just discovered some pretty incredible mineral specimens – a pocket of gem quality tremolite at the contact between quartz and calcite veins. Tremolite evolves to actinolite under the right conditions, and sometimes changes to diopside. Anyway, the finer points of the discovery are detailed on my youtube site (caver461) and within the video details are provided for the purchase of my latest book on minerals – ‘Rockhound: An Experience of the North’. In the book I detail how to find gemstones and something of the experience of finding rocks and minerals in the north.
