The Earth has the greatest abundance and variety of sedimentary strata in our star system, dating back some 3.8 billion years. ‘Sedimentary rocks’ describes the processes that create different types of sedimentary rocks, which form a key guideline in reconstructing Earth’s history. Particles are created by both physical and chemical weathering.

The factor of grade size is the one most used for the classification of sedimentary rocks (p. 190). Four groups may be distinguished:— 1. Rudaceous 1—Rocks consisting chiefly of gravel, pebbles, cobbles, or boulders. Loose materials of this class are gravels, pebble-beds, shingle, boulder-beds, scree, talus, etc.

Abstract Over vast areas of the undeformed platform of southwestern Canada, the sedimentary cover of the ancient North American Craton is entirely of Phanerozoic age. In northwestern Canada, on the other hand, thick Proterozoic strata intervene between Phanerozoic deposits and crystalline basement (Fig. 4A.1).
