Description:
A Number of small pegmatitic patches occur in the development of the later stages of the hornblende hybrids of the Cairnsmore of Carsphairn Complex. These are best seen on the eastern side of the Gairy of Cairnsmore, and it is within these pockets of late residuum crystallization that this hornblende occurs. The pegmatites consist of milky quartz, greenish-black hornblende and a clove coloured sphene. The two latter minerals develop idiomorphic crystals. The hornblende, though usually only 1½ inch in length, occasionally grows to 1½ inches long in slender prismatic crystals showing the faces (100), (110), (110), (130), (130), (010), (011), and (011).
