limnic, a. Geol.|ˈlɪmnɪk|
[ad. G. limnisch (C. F. Naumann Lehrb. d. Geognosie (1850) I. ii. iii. 814), f. Gr. λίµνη pool of standing water, marshy lake: see -ic.]
Formed or laid down in an inland body of standing fresh water such as a lake or a swamp.
[1911Proc. Amer. Philos. Soc. L. 28 Naumann recognized the distinction between deposits formed on the sea border and those in fresh-water lakes... These types he terms paralisch and limnisch. Ibid. 29 The causes in paralisch areas are different from those in limnisch basins.] 1940A. C. Noé tr. Stutzer's Geol. Coal vi. 159 Coal basins which have originated near the sea are called ‘paralic basins’; and coal deposits which were formed inland..‘limnic deposits’. This classification goes back to Naumann. Recent peat bogs can also be similarly classified. In the interior of a country—for instance, on the northern edge of the Alps—are found limnic moors, while the paralic moors are situated on the coast, as in Friesland. 1968M.-Th. Mackowsky in Murchison & Westoll Coal xiv. 327 In the Upper Carboniferous large paralic coal deposits formed along the northern border of the Variscan mountains. Somewhat later the limnic coals of the Saar, Lorraine and central and south-eastern France developed in troughs between the mountains. 1971Nature 30 Apr. 561/1 Tobien et al. have excavated a primitive, forest-adapted Hipparion fauna..from tuffaceous and limnic beds on the flank of the Höwenegg volcanic centre in southern Germany. |
