Book Description

Excerpt from Central Connecticut in the Geologic Past Geologic History expressed by Structure Sections. Geologic studies commonly center in a written description, andare illus trated by maps and structure sections which Show the rock formations as they exist at the present time. In this article the form Of presentation is reversed, and the later geologic history of central Connecticut is made to center about a succession Of graphic portrayals, with written descriptions to precede and ex plain these views. A structure section passing east and west near Meriden and Middletown Shows the rock formations as they would appear on the walls of a deep trench, and the surface outline shows the magnitude and relations of hills and valleys. Upon this structure section, as upon a wide canvas, the spectator may in imagination review the changes which have passed from age to age over this one portion of the earth. The structure section of Present Geologic Time, as shown in Figures 1 and 2, is based upon the location of surface out crops, and the information which these give to the geologist con cerning the underground structure. But, except for the surface line, this, like other structure sections, is the product of the scientific imagination. The deeper the section is carried and the more complicated the geology, the more it must fail of accuracy.
