1961J. Braunstein in Bull. Amer. Assoc. Petroleum Geologists XLV. 2017/2, I dare to submit two new terms... These are, ‘calciclastic’.., referring to clastic carbonate rocks, and, ‘siliciclastic’.., referring to clastic non-carbonate rocks (which are almost exclusively silicon-bearing, either as forms of quartz or as silicates). 1976Nature 3 June 440/1 Two major subdivisions are considered—the siliciclastic and carbonate tidal deposits. Recent siliciclastic examples include the classic tidal flats of the North Sea, [etc.].

Roux has grown a number of silicicolous (arenaceous) plants in calcareous soils, and finds that..the seedling plants develop tardily and imperfectly. 1932Fuller & Conard tr. Braun-Blanquet's Plant Sociol. vi. 187 In humid regions the leaching of carbonates sets in upon dolomite.., and acidophilous plants follow in the train of the progressive acidification of the dolomite soil. This occurrence of silicicolous plants on dolomite substrata was first noticed by Sendtner.
