Open File Report LXV – Geology of Chippewa County, Michigan - VerWiebe – Page 1 of 33 GEOLOGY OF CHIPPEWA COUNTY MICHIGAN

The earliest comprehensive work on the geological formations in this county was done by Carl Rominger. He published his findings in volume 1 of the Geological Survey of Michigan in 1873. It appears from a careful reading of this report that Rominger visited practically every one of the isolated outcrops on the mainland portion of the county, and a good many of those located on the islands which...

The Prairies of the E . Lucy Braun Preserve , Adams County , Ohio : A Soil Study

Analysis of samples of the 0 to 10-cm soil depth collected at 65 locations under six vegetation communities snowed that prairie and cedar-hardwood communities occurred on calcareous (range, pH 6.97.9) soils with low silt concentrations (20-54%), and that pine and oak communities occurred on acid (pH 4.36.3) soils with high silt (54-80%); this represented a distinction between communities on soi...

As magmas rise toward the surface, they traverse regions of the mantle and crust with which they are not in equilibrium; to the extent that time and the intimacy of their physical contact permit, the melts and country rocks will interact chemically. We have modeled aspects of these chemical interactions in terms of ion-exchange processes similar to those operating in simple chromatographic colu...
