Extract

While studying the Cornish mineral deposits I have examined certain thin-sections cut from granite-porphyry dykes which contain numerous quartz or felspar veinlets. The structures in these veinlets and their behaviour towards the various constituents of the host rock are, I believe, sufficiently interesting to merit detailed description. The sequence of events to be deduced from these features is not commonly recognized, and the underlying principles may have a broader application to include some of the larger mineral veins in Cornwall.
