The gold,which occurs native and at times contains small quantities of silver, is found indark scams in the fractured quartz, with calcite. sericite, talc, chlorite and minerals as chalcojiyrite. molybdenite, pyrrhotite, barite. galena, tourmaline The Shiningtree Silver Area, Ont.

Veins are little faulted, but they have been sub-jected to all degrees of folding and brecciation. Great pressures have been appliedfrom the north and south, hence the rocks have developed into schists with nearlyeast-west strikes; the north-south veins, like the Ribble, Herrick and Gold Corona,have been compressed lengthwise, and thus greatly folded and in parts east-west veins are little folded, liaving been compressed on the sides, while theveins with an intervening strike like the Saville. which runs northwest-southeast,are less folded and less broken than the nortli--outh veins, but more so than theeast-west veins. ^Nlost of the gold dejiosits are cut by diabase dikes, usually withoutbeing displaced.
