Flow Directions

The flow directions of ice lobes within the Erie basin may be deduced from heavy-mineral assemblages of the Hayesville, Hiram, and Ashtabula tills deposited during the Port Bruce Stade after the Erie Interstade. These tills have heavy-mineral assemblages dominated by purple garnet, green hornblende, and clinopyroxene. Oolitic hematite occurs in all tills, but is dominant in the Ashtabula Till. The probable source of hematite is the Furnaceville Ironstone Member of the Clinton Group which crops out south of Lake Ontario. Trilinear plots of purple garnet – red garnet – epidote suggest that the eastern Grenville Subprovince is the provenance of all three tills. Southwestward-flowing ice of an Ontario–Erie lobe deposited these tills in the Erie basin. The Huron–Erie lobe did not deposit tills along the south shore of Lake Erie after the Erie Interstade.

Lake Nipissing is situated 230 miles north of Lake Ontario and roughly 140 miles within the igneous rock territory. Some 30 by 8 miles in size, it is drained westerly by the French River into Lake Huron. Frank Bay, enclosing an area of one half square mile, is situated on the south shore at the entrance to the French River. Historically the area was occupied by an Algonkian group called “Nipisinieries” or “Nipissings” by the 17th century Jesuits; Galinee's map of 1665 depicts a bay on the south shore of Lake Nipissing at the head of the French River: “In a bay at this place the Nipissings usually locate their village” (Coyne, 1903). The site described here, probably the one figured by Galinee, is a level tract of about one half acre constructed by wave deposition of coarse sand upon a low area at the bottom of the bay.

At Wooster, Ohio, this species was observed in the fieds on May 26, and at Alliance, nearly due east, on October 24, while at Bridgeport, in the extreme eastern central part of the State, it was found, active, on November 4, all during 1898. It appears to have been more numerous of late in the vicinity of the south shore of Lake Erie than elsewhere in the northern portion of the State, and more abundant than I have formerly observed it in the same latitude in Indiana and Illinois.

In the 1969 summer season mapping was concentrated in those areas of southern Scoresby Land and northern Jameson Land which had not been visited in 1968 (see Birkelund & Perch-Nielsen, 1969). Mapping was extended westward to the main fault of the post-Caledonian sedimentary basin against the Stauning Alper and to the south as far as 71°10'. The field work was carried out by R. G. Bromley, L. and C. Malmros, K. Perch Nielsen, J. Bruun-Petersen, C. Heinberg, and E. Hjelmar. The preliminary results of the mapping are given in this report together with a geological map at a scale of 1:300 000, compiled from the existing maps (Aellen, in press; Bearth & Wenk, 1959; Callomon, in press; Triimpy & Grasmiick; 1969) and our own observations. Special attention was given to trace fossils by. R. G. Bromley and the heavy mineral assemblages in the Mesozoic sediments by J. Bruun-Petersen.

Heavy Mineral Analysis

AbstractThe ice caps that covered large parts of the continents of the northern hemisphere during the Pleistocene glaciations drained huge quantities of meltwater. In several places the erosive power of the meltwater rivers has led to the formation of ice-marginal valleys (IMVs). A much-debated question is whether sediments deposited in IMVs by proglacial and extraglacial streams can be distinguished on the basis of their heavy-mineral content. This question was assessed by an inventory of the heavy-mineral assemblages from the middle part of the Toruń-Eberswalde IMV in northwest Poland, two sandurs that supplied sediment from the north and the pre-Wisła river system that supplied sediment from the south; all these streams fed the IMV. The largely similar heavy-mineral compositions and sediments concentrations of the middle part of the IMV and sandurs suggest that the sediment in the IMV was supplied almost entirely by the streams on the sandurs but also that some sediments were eroded from the Miocene subsoil of the IMV itself and for a small part from the south by the pre-Wisła river system. The only heavy mineral in the pre-Wisła sediments for which the percentage is significantly different from those in the sediments of the sandurs and the IMV terrace is epidote. The difference, however, is not seen in the sediments of the IMV so it can be concluded that the sediment supply to the middle part of this IMV by streams from the south was insignificant. This is in contrast with what was hitherto commonly assumed.

South Shore

Much of Lake Erie' s southern shoreline displays fairly uniform properties with respect to shore processes. However, detailed studies of selected stripe of shore areas often reveal characteristics which are so distinctive that problems of control require special attention to local characteristics. The purpose of this paper is to present some generalizations and some detailed comments on the motion of sediment along the south shore of Lake Erie, to outline the results of some detailed studies of small areas, and to evaluate the types of evidence used in such studies.

Wave Erosion

The final advance of the Erie lobe into Ohio during the Port Bruce Stade of the Late Wisconsinan deposited the Ashtabula Till. Wave erosion and mass wasting along the south shore of Lake Erie show that the Ashtabula Till consists of laterally traceable lithofacies, which are used to determine the depositional history of the Ashtabula Till. At each section, lithofacies sequences are divided into two sub-sequences, each consisting of massive, matrix-supported diamicton (Dmm) overlain by stratified, matrix-supported diamicton (Dms). Some Dmm are sheared (Dmm(s)) and are interpreted as lodgement till, whereas other Dmm and Dms were deposited as melt-out till. Some sections contain lenses of fines (Fm and Fl), current-reworked diamictons (Dmm(c) and Dms(c)), and resedimented diamictons (Dmm(r) and Dms(r)). The two sub-sequences represent two advances of Ashtabula ice that deposited the Euclid and Painesville moraines about a kilometre apart. During and after recession of the Ashtabula ice, waves and currents in Lake Maumee and its successors reworked outwash and diamictons to form the lake plain. The texture of Dmm(s) is significantly different from that of most other diamictons, and Dmm has the smallest carbonate content of all diamictons. Analysis of the variations in texture and composition among lithofacies provides additional evidence of the effectiveness of lithofacies logging in interpretation of glacial processes.
