What reading level is Key to a Chart of the Successive Geological Formations With An Actualsection Fr book?
To quickly assess the difficulty of the text, read a short excerpt:
Above the Coal measures, and overlying them, sometimes conformably, and at other times unconformably, is found a series of red sandstones, red, green, and variegated shales, marls, and sandstones, with yellow magnesian limestones. These contain few traces of vegetation, and the organic remains are quite distinct from those in the rocks below. The system has been divided into Permian and Triassic systems.
The rocks recognized as of the New Red Sand- stone period, are the sandstones and shales of... the Connecticut River valley, New Jersey, Virginia, and North Carolina. These belong apparently to the Triassic System, and represent a portion of the upper marls and sandstones of the period, as more fully developed in Europe. The remains of fishes, and the tracks of birds, which have been so beauti- fully developed and illustrated by Professor Hitch- cock, Dr. Deane, Mr. Redfield, and Mr. Marsh, are among the interesting fossil remains of this period in the United States.
It will be observed that no American localities are given upon the chart for any of the strata of the Permian system, none of its members having yet been found in this .
