	Schist: Definition and Links by Encyclopedian.com
		The schists form a group of metamorphic rocks chiefly notable for the preponderance of lamellar minerals such as micas, chlorite, talc, hornblende, graphite, etc. Quartz often occurs in drawn-out grains to such an extent that quartz schist is produced.
		Most schists have in all probability been derived from clays and muds[?] which have passed through a series of metamorphic processes involving the production of shales, slates and phyllites[?] as intermediate steps.
		Schists are named for their prominent or perhaps unusual mineral constituents, such as garnet schist, tourmaline schist, glaucophane[?] schist, etc. The word schist is derived from the Greek meaning to split, which is in reference to the ease with which schists can be split along the plane in which the platy minerals lie.

		The next question respecting the schist is, whether its position in different places bears any relation to the granite mass, or rather to the forms of the mountains ; since the quantity of granite here visible is too trifling to admit of any comparison of this nature.
		It was that of a rounded pebble imbedded in the clay slate, at the mouth of the Santon river.
		The junction of this conglomerate with the schist may be traced in the high banks which form the shore, where it is indicated in the map.

		Near the Santon river, at the junction of the schist, and where one of the most conspicuous and interesting of these masses is to be seen, no shells occur for a considerable space.
		It consists of fragments of schist, quartz, and limestone, united by a calcareous base, and is of a coarse texture.
		Near the point where the schist and sandstone unite, in the neighbourhood of Peel, a conglomerate of rolled pebbles is seen adhering to the face of the schist, which is here vertical and even.

		The Seward terrane, an area 150 by 150 km in the central and eastern peninsula, is dominated by Precambrian(?) and early Paleozoic blue schist-, green schist-, and amphibolite-facies schist and marble, and intruded by three suites of granitic rocks.
		The York terrane, roughly 100 by 75 km, occupies western Seward Peninsula and the Bering Straits region; it is composed of Ordovician, Sulurian, Devonian, Mississippian, and possibly older limestone, argillaceous limestone, dolostone, and phyllite, which are cut by a suite of Late Cretaceous tin bearing granites.
