glacier cornice . A projecting mass of glacier ice. It was formerly underlain by ice containing numerous rock fragments which, when warmed by solar radiation, melted the ice around them and caused the ice above them to project like a cornice (Hobbs, 1912, p.397).
salt lick . A place to which animals (e.g. deer, cattle, bison) go to lick up salt lying on the surface of the ground, as in an area surrounding a salt spring. The term has been used for the spring itself, but this usage is improper because a lick is dry. Syn: lick.
channel geometry . The description of the shape (form) of a given cross section within a limited reach of a river channel. See also: river morphology.
meltwater (melt'-water). Water derived from the melting of snow or ice, esp. the stream flowing in, under, or from melting glacier ice.
branchwork cave (branch'-work). A cave in which the passages intersect as tributaries. See also: network cave; maze cave.
brachygenesis (brach-y-gen'-e-sis). The phenomenon in evolution in which part of a presumed recapitulated sequence has evolved outward and no longer appears in the course of development. Cf: acceleration.
high marsh . A syn. of salting. The term is a "less correct and rather obsolete" syn. of salt marsh (Schieferdecker, 1959, term 1243).
zhamanshinite . Glass associated with Zhamanshin crater, Russia, thought to have been produced by melting of local target rocks during an impact event. Cf: impactite.
topo-stratigraphic unit (top''-o-strat''-i-graph'-ic). A term proposed by Jaanusson (1960, p.218) for a "convenient regional stratigraphic unit" consisting of a combined rock unit and biostratigraphic unit. Equiv. to the mixed topostratic unit of Henningsmoen (1961).
