gs: therefore, are older than these beds which are at least as old as mid-Miocene. It seems best to consider the Etheline formation as of Eocene age and probably early Eocene. SKONUN! FORMATION. The name Skonun is given to a sedimentary formation included in the Tertiary rocks of the Queen Charlotte islands. Distribution. These sediments have been observed in section 1 of township 7, on the lower Yakoun river, on the Mamin river, and at Skonun point on the north coast. They are reported to occur at the mouth of Miller creek, about 8 miles north of Skidegate post-office, at Meyer lake, at Tow hill, and at other localities in the northeast lowland. Although these are only a few outcrops scattered over a large expanse of territory, it is believed on topographic evidence (See Chapter III) that the Skonun formation underlies the greater part of the northeast lowland. Lithology. The character of this formation varies from place to place, exhibiting differing degrees of consolidation at different points. On the Yakoun river, the formation is made up of flat lying, slightly cemented sand and fine gravel, and tough, soft, grey clay. The sand which is on the whole coarse is white to light grey in colour, and largely composed of quartz. AtSkonun point on the north coast, similar beds occur dipping at angles up to 60 degrees, but there they are quite hard and well cemented by calcite (see Plate XIIA.) Lenticular bands of grey lime- stone up to 2 inches thick are also found in these sandstones. Conglomerates occur there, and also thick beds of lignite. Lignite has been reported to occur also at Miller creek, Mamin river, Naden harbour, and various points on the east coast. It is evidently wide-spread through the formation. Fossil shells and leaves have been found in the clays on the Yakoun river, and shells are very abundant in the sandstones of Skonun point. Structure. The sediments on Yakoun river and at Skonun point are in layers from 1 foot to upwards of 10 feet thick, and 1 Named from Skonun point.
