Excerpt from The Calcite Marble and Dolomite of Eastern VermontThe marble contains some schist and dolomite lenses. It is strongly plicated, the axes of the folds having the strike of the ridge but pitching 65° S. -the schist in contact with it has similar plications but a slip cleavage striking about north and dipping steeply east. At the S. 17 W. End the marble plications pitch southward under the schist, but at the N. 17° E. End the schist underlies the marble, which is only 18 to 24 inches thick. The surface form shows that the outlier was Originally over 30 feet long and about 12 feet wide, though tapering to half that width at the south, but has been dis solved away. The schist has deep glacial striae trending S. 50° - 55° E. The course of the plications on the marble Surface, meandering from east to west, is the result of a transverse compression that gave the normally plicated beds a steep southerly pitch and produced a system of small transverse folds along the strike (see fig. In the synclinal part of one of which the little outlier has been preserved from further erosion.The economic bearing of the outlier on the larger marble outcrops is important, for it shows that these folds are not anticlines projecting through the schist but synclines underlain by schist and therefore contain but a very small amount of marble.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
