Page 26 - CARBONATE of LIME. Lime combines with great avidity with carbonic acid, a gaseous acid only obtained fluid when united with water, — and all combinations of it with other substances are called Carbonates. All limestones are carbonates of lime, and quick lime is obtained by driving off the carbonic acid by heat.
Page 49 - Scotland dikes, the provincial name for wall. It is not easy to draw the line between dikes and veins. The former are generally of larger dimensions, and have their sides parallel for considerable distances; while veins have generally many ramifications, and these often thin away into slender threads.
Page 173 - An Italian name for a variety of volcanic rock, of an earthy texture, seldom very compact, and composed of an agglutination of fragments of scoriae and loose matter ejected from a volcano.
Page 5 - ALLUVIUM. Earth, sand, gravel, stones, and other transported matter which has been washed away and thrown down by rivers, floods, or other causes, upon land not permanently submerged beneath the waters of lakes or seas.
Page 17 - ... columns. Remarkable examples of this kind are seen at the Giant's Causeway, in Ireland, and at Fingal's Cave, in Staffa, one of the Hebrides. The term is used by Pliny, and is said to come from basal, an Ethiopian word signifying iron. The rock often contains much iron.

Page 34 - ... wherever any of the varieties of coal form a principal constituent part of a group of strata. Conformable. When the planes of one set of strata are generally parallel to those of another set which are in contact, they are said to be conformable. Conglomerate or Puddingstone. Rounded water-worn fragments of rock or pebbles, cemented together by another mineral substance, which may be of a silicious, calcareous, or argillaceous nature.
Page 32 - The planes of cleavage, therefore, are distinguishable from those of stratification; and they also differ from joints, which are fissures or lines of parting, at definite distances, and often at right angles to the planes of stratification. The partings which divide columnar basalt into prisms are joints. The masses of rock included between joints cannot be cleaved into an indefinite number of laminse or slates, having their planes of cleavage parallel to the joints.
Page 105 - LIMESTONE. An extensive series of beds, the geological position of which is immediately above the coal-measures,— so called because the limestone, the principal member of the series, contains much of the earth magnesia as a constituent part.
Page 49 - When a mass of the unstratified or igneous rocks, such as Granite, Trap, and Lava, appears as if injected into a great rent in the stratified rocks, cutting across the strata, it forms a dyke ; and as they are sometimes seen running along the ground, and projecting, like a wall, from the softer strata on both sides of them having wasted away, they are called in the north of England and in Scotland dykes, the provincial name for wall.
