Flowtill in Southeastern Massachusetts

Investigation of Facies Types and Associations of Kuhlan Red Bed Formation in NW Yemen: A New Hypothesis for Origin and Depositional Environment

“…The diamictites have been described to be the deposition of lodgment till at the time of glacial entrance in the sea or the drop down of lodgment clasts from the floated icebergs up on argillaceous sandy matrix (Walker, 1984b;Reading, 1986;Deynoux et al, 1991;Einsele, 1992;Walker and James, 1998;Crowell, 1999). The faint bedding and clusters of pebbles observed in the diamictite may correspond to shear planes and lodgment which characterized basal tillite (Dretmants, 1969;Boulton, 1970;Reading, 1986;Einsele, 1992;Walker and James, 1998) or debris flow processes which operate in flow tills (Hartshorn, 1958).…”

Surficial geologic map of the Voluntown quadrangle, Connecticut-Rhode Island

“…Two small patches of till, each less than 300 feet in diameter, are surrounded by glaciofluvial deposits of group 2 one mile southeast of Voluntown. It is not known whether these patches are the protruding summits of ground moraine hillocks, or whether they are · sheets of flowtill (Hartshorn, 1958} that slid from adjacent stagnant ice masses during or after glaciofluvial deposition.…”

An early Holocene glacial advance in the Macaulay River valley, central Southern Alps, New Zealand

“…If this were so, however, the materials can have originated only from upvalley in the terminal moraine loops where they are breached, or on a steep glacier surface sloping upvalley from the innermost of them. If the latter were the case, the deposits would fitthe definition offlow till (Hartshorn 1958). Whether the materials originated at the moraines, or on the glacier surface associated with them, we believe that such large flows would have required the glacier to have been abutting the moraines, in order to provide the hydrostatic conditions to initiate flow.…”
