The Geology of Delaware

The Geology of Delaware is an online resource for information about the geology and hydrogeology of Delaware. Although common geologic terminology is used throughout, most information on these pages is explained in general terms. There are many publications available from the Delaware Geological Survey that provide detailed information and the latest research about the geology and hydrogeology of the state. DGS also releases much of the data associated with the publications in digital format. Feel free to browse through these sections to learn more than what is covered in this online book.

How to Use this Book: Each page in this "virtual" book is located inside a chapter. The chapter in which the current pages reside can be identified in two ways: 1) the breadcrumb at the top of the page, labeled "You are here," and 2) the Table of Contents menu at the right of the page, which should be open to the current page.

At the bottom of each page is a small navigation menu. This menu provides links to the previous page (in respect to the page order in the book) at the far left, to the next page at the far right, and up to the current chapter home. The chapter home page lists all pages and sub-chapters contained in that chapter, and is identical to what is displayed in the Table of Contents menu at the left.
