Page 77 - Sow." It will be noticed that this interpretation of the section agrees more nearly with the correlation of Prof. Stevenson than with that indicated by the other Pennsylvania geologists for eastern Pennsylvania. It is probable that, beginning with the greenish shales and sandstones of the Starucca and the New Milford red shales, there is a series of deposits equivalent to the Oneonta sandstone of New York, which, as is well known, gradually parses into beds of typical Middle and Upper Portage in...

Page 77 - ... square miles, while the whole area under consideration is more than 30,000 square miles. To explain the absence of life is not easy; it cannot be due merely to an agent which caused the redness or greenness of the beds, for, in Huntingdon and Fulton counties of Pennsylvania, the Montrose shales have many fossiliferous beds though having also many green and red beds. Besides, the Delaware section shows a great thickness of beds of other colors, which are equally without animal remains. It cannot...
Page 18 - ... Chemung formation passes insensibly up into Catskill, by a series of transition beds ; more olive than red below, more red than olive above ; the fossils also ascending and mixing like the colors. South of Lock No. 7 the Genesee shales are exposed for over a mile to below Lock No. 9 at Weissport. Their fissile and broken character is well shown here ; in places they are so black that the rock looks more like weathered coal, or highly carbonaceous shale.
Page 9 - ... The Chemung rocks make a steep, high ridge directly north from the Genesee slate valley, and extend parallel with it about S. 70 W. across the township. These beds are well exposed along the road, just below Spragueville. where they dip N. 25 W. 25-30. Along the county road, about one half mile below Spragueville, the Chemung rocks are seen in cliffs of gray, finegrained sandstone, quite fossiliferous. A coarse, yellowish-gray sandstone occurs about 200' below the top of the Chemung,...
Page 49 - County, is 0 miles northeast of Cuddebackville, or 4 miles southwest of Summitville which is on the main line of the New York, Ontario and Western Railroad. Nearly 2 miles northwest of the village and more than 500 feet higher', is the Clark quarry, which was operated by Charles Green in 1891. The flagging is rather coarse-grained, gray sandstone, covered with a considerable thickness of greenish to olive-colored argillaceous shale. The dip of the lowest bed exposed is 19, while the highest shows...
Page 27 - Bushkill, one mile and a half above its junction with the Big Bushkill. Here it is a perfect mass of corals, and shells for about 30', a great number of species and genera being represented, among which the following were recognized : Zaphrentis Rafinesquii, Z. gigantea, Heliophyllum Halli, together with several species of Syringopora, and other forms that I could not determine. This is by far the richest coral horizon in the district, being in fact a regular fossil reef. The calcareous portions...
