1887J. J. H. Teall in Geol. Mag. IV. 493 Some modification in the use of the term clastic is rendered necessary... I venture to suggest that it should be applied to all rocks which consist largely of mineral fragments and that we should distinguish between the three types of clastic rocks..by using the terms epiclastic, cataclastic, and pyroclastic. Epiclastic—Rocks formed of fragments resulting from the breaking up of older rocks occurring upon the earth's surface. |
