Guidebook to the depositional facies of Wisconsinan ice-sheet materials of the Scioto Glacial Lobe
, central Ohio.
This is probably a correlative of the Farmdalian interstadial substage described (by Frye and Willman 1960) in the area of the Lake Michigan glacial lobe.
Classification of the Wisconsin stage in the Lake Michigan glacial lobe.
The source and provenance of these Paleozoic microfossils would require careful correlation of types and frequencies of the palynomorphs with in situ rock strata in the areas overridden by the Saginaw glacial lobe.
The locality is at the extreme outer margin of the Kalamazoo-Mississinewa moraine complex, adjacent to the retreating margin of the Saginaw glacial lobe (Farrand and Eschman 1974).
However the sand size fractions of tills from the Lake Michigan and Saginaw glacial lobes
are dominated by quartz and feldspar at all size fractions and do not show an increase in denser minerals at finer grain sizes.
The more rapid movement of glacial lobes
in the lowland to the east and the region to the west resulted in the final joining of these ice lobes south of the Driftless Area, so that it was completely surrounded by the continental glacier; 3.
Pebble and sand lithology of the major Wisconsin glacial lobes
of the Central Lowland.
At the maximum extent, the glacial lobes completely covered Michigan and expanded into south central Indiana and southwestern Ohio.
approximately one-half of the land surface of the lower peninsula was deglaciated with the hilly topography of the areas between the major glacial lobes already exposed.
