The Quaternary Geology of the New Haven Region, Connecticut (Classic Reprint)


Book Description

Excerpt from The Quaternary Geology of the New Haven Region, Connecticut Among the papers listed in the Bibliography Of Connecticut Geology (state Geological and Natural History Survey Bulletin 8, 1907) are many relating to glaciation. Most Of them deal with Connecticut as a whole or with principles illustrated by glacial phenomena within the State. The present report is the result Of the study of a relatively small area and is based on field observa tions made in 1909 and 1910, supplemented by material taken from a thesis presented -to Yale University.

The Geological History of the Connecticut Valley of Massachusetts


Book Description

Excerpt from The Geological History of the Connecticut Valley of Massachusetts: A Popular Account of Its Rocks and Origin The purpose of this little book is to present, in popular form, the salient points in the geological history of the Connecticut Valley of Massachusetts. The beautiful valley and its charming boundary hills may in truth be said to be a geologist's paradise. In regard to variety of geological phenomena, few districts of equal size in North America surpass it. To most of its residents the marvelous story of the Connecticut Valley and adjacent hills as recorded in nature's book of the rocks is unknown. Beginning with the oldest decipherable records and leading up to the present time, it is my pleasure, in the following pages, to explain to the layman the principal known events in the wonderful geological history of the Connecticut Valley, including the origin of the valley as we see it today. The use of technical and unusual terms has been reduced to a minimum compatible with a reasonable understanding of the subject. Each of the few technical terms is explained where first used in the text. Since so many of the great principles of earth science (geology) are wonderfully illustrated in the Connecticut Valley and the adjacent highlands, it is my hope that this book may furnish the basis and inspiration to many people of the region for understanding and interpreting not only the principal records of the rocks, but also the important processes and laws of the science of geology illustrated by these records. To aid in the accomplishment of this purpose, simplified, largely nontechnical, scientific discussions are entered into. In order to make the conclusions more impressive and realistic actual easily accessible localities, carefully selected out of my field experience, are cited to illustrate each stage in the tremendously long history of the region. I am not satisfied to say to the reader, for example, long ages ago, according to geologists, the sea spread over central western Massachusetts. My purpose is to be much more precise than that, and to give the reader at least some of the geological reasoning upon which such conclusions are based.

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1870 edition. Excerpt: ... From the Author. prom The Transactions Op The Conn. Acad. Op."abts And Sciences, Tol. ii On The Geology Of The New Haven Region, '-With Special Reference To The Origin Of Some Of Its Topgpaphical Features. By James D. Dana. ""'." "" With A Map. ' _.," 1. The New Haven Region. .," ' Either side of New Haven bay, --an indentation of the coast.aibbiit four miles in depth, --there is a north-and-south range of hills', th'e trap and sandstone ridges of East Haven and North Haven on the eft's,"' and the eastern portion of the Woodbridge plateau on the west; and-."'these make the eastern and western boundaries of the New Haven region. Their height, which is greatest to the north, probably nowhere exceeds 600 feet. The width of the region varies from about four miles on the south to seven on the north, and the whole length from the Sound to Mt. Carmel--its true northern topographical limit--is twelve miles. The northern half of the region is divided longitudinally by two lines of ridges: (1) the long West Rock trap ridge near the western side, four hundred feet and upward in height; and (2), nearly midway in the area east of West Rock, the short isolated East Rock (E) range of trap and sandstone, and the continuation of this range northward to Mt. Carmel in the low Quinnipiac sandstone ridge which divides the waters of Mill River and the Quinnipiae. The New Haven region hence consists in its northern half of three subordinate north-and-south regions; (1) a narrow valley west of West Rock, drained by West River; (2) a broad central plain (the Hamden plain), continuous with the New Haven plain, rising into hills to the northward, and drained along the east side by Mill river; and (3) a wide eastern portion occupied by the river-course and...




The Quaternary of the U.S.


Book Description

This important volume reviews the status of investigations aimed at deciphering the geologic, biogeographic, and archaeological records for the Quaternary Era—the last million years of geologic time-for the area of continental United States. Over eighty Quaternary scientists have contributed to the fifty-five chapters divided into four main parts. Part 1 treats the areal geology, with emphasis on the stratigraphy of the glaciated areas east of the Rocky Mountains, unglaciated eastern and central United States, and western United States. Part 2 deals with biogeography: phytogeography and palynology, animal geography and evolution. Part 3 deals with archaeology prehistory in the northeastern states, southeastern states, plains, desert west, and Pacific Coast including Alaska. Part 4 covers many diverse Quaternary studies on—the continental shelves, isotope geochemistry, paleopedology, the geochemistry of some lake sediments, paleohydrology, glaciers and climate, volcanic-ash chronology, paleomagnetism, neo-tectonics, dendrochronology, and theoretical paleoclimatology. Originally published in 1965. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
