Seite 19 - Amboy, and if the depression south of the Raritan River were forty to fifty feet. Black color indicates land not covered by waters during the hypothetical depression. The outline represents the present coast. In conclusion, it may be stated that, while no single argument seems to be fatal to the salt-water hypothesis accounting for the Hudson water body, unless those drawn from the phenomena on the outside of the moraine be such, it is likewise true that the facts are not fatal to the lake hypothesis,...
Seite 7 - Very respectfully, CW HAYES, Geologist in Charge of Geology. Hon. CHARLES D. WALCOTT, Director United States Geological Survey.
Seite 12 - District6 is a careful description of outcrops examined along longitudinal sections of the island, corresponding in position with the principal avenues. This descriptive matter has much value as a record of exposures, many of which have since been pared away in grading the city. He says in re'sume': The general direction of the strata is N. 25° E. to N. 35° E. and corresponds with the direction of the avenues; and the dip, though generally to the west, averages within 10° of the vertical.
Seite 14 - Am. Jour. Sci., XX., pp. 436 and 441. tended and thin a stratum could by any possible convulsion be doubled up together so as to give these results. The synclinal mapped seems beyond dispute ; as for dividing up the strata each side of it, I do not feel justified in doing it.
Seite 11 - ... the enormous increase in the value of real estate upon Manhattan Island. It is resulting in a paring down of all rock masses which project above the general level in order to make room for business blocks and apartment houses. The greater number of the rock exposures described by Dana and other early observers are now no longer seen, and those still uncovered by blocks and pavements will in a very few years have disappeared from view. After reviewing briefly the structural geologic studies made...
Seite 18 - ... and staurolite. Then ensued the general impregnation of all the layers with pegmatitic material. Next came the intrusion of a series of pegmatite dikes, cutting each other in succession, and all, so far as yet known, intersecting the pegmatite lenses of the preceding generation. With these erogenic movements seem to have been connected, with extensive folding, crumpling, and faulting of all the beds of gneiss, schist, and limestone, and a further increase of crystalline structure, development...
