Abstract
The Meldon aplite is a small intrusion lying to the north-west of the Dartmoor granite about two miles south-west of Okehampton. Its microscopic characters were investigated by Sir Jethro Teall, whilst the geology of the district, with petrological accounts of the aplite and its associated rocks, has been fully dealt with by R. H. Worth, who notes the presence of felspar, quartz, mica, tourmaline, topaz, apafite, fluor-spar, montmorillonite, and axlnite.Keywords
