That night, the rumors about Weaver's pregnancy widened into open conversation as four Deltas chatted over ice cream.
In an adjacent location, the ice-margin mounted and advanced over the ice-contact delta to create a push moraine at the limit of the advance by subglacial gravity-spreading.
That night, four Deltas went out for ice cream in the small college town of New Concord, Ohio.
During deposition of the ice-contact delta, escaping subglacial regelation-meltwater permeated the proximal deltaic sediment pile and calcium carbonate was released, in a series of pulses, to form pore-occluding calcite cement within the sand and gravel porespaces.
The possibility that they are due to shorter progradation distances than the underlying stage III deltas, due to ice-confinement or lower volumes of supplied lava is also considered.
In one location, the ice advance pushed the delta pro-glacially to form a prominent single-crested push moraine.
The location, elevation and geomorphology of glacigenic deltas reflect the position of the ice margin during retreat and the dynamic processes of meltwater and sediment production.
This paper investigates a Quaternary Gilbert-type gravel delta that was formed in an ice-marginal environment at the end of the last glacial period.
The correspondence between ice ages and negative delta-C-13 excursions may reflect the effects of lowered sea levels; enhanced circulation of deep, cold, O2-rich seawater; and/or the upwelling of C-13-depleted deep water.
The onset of delta progradation probably represents a halt in ice advance and a related high sediment supply period.
Cores from a solifluction sheet, alluvial fans, and an emerged delta were studied with regards to cryostructures, ice and total carbon contents, grain size distribution, and pore water electrical conductivity; and the samples were AMS 14C dated.
