Geology is a science of
such rapid growth that no apology is expected when from time to time a new
text-book is added to those already in the field. The present work, however, is
the outcome of the need of a text-book of very simple outline, in which causes
and their consequences should be knit together as closely as possible,—a need
long felt by the author in his teaching, and perhaps by other teachers also. The
author has ventured, therefore, to depart from the common usage which subdivides
geology into a number of departments,—dynamical, structural, physiographic, and
historical,—and to treat in immediate connection with each geological process
the land forms and the rock structures which it has produced. In arrangement,
the twofold division of the subject was chosen because of its simplicity and
effectiveness. The principles of physical geology come first; the several
chapters are arranged in what is believed to be a natural order, appropriate to
the greatest part of our country, so that from a simple beginning a logical
sequence of topics leads through the whole subject. The historical view of the
science comes second, with many specific illustrations of the physical processes
previously studied, but now set forth as part of the story of the earth, with
its many changes of aspect and its succession of inhabitants. Special attention
is here given to North America, and care is taken to avoid overloading with
details.
This
course note introduces students to the basics of geology. It will addresses
topics ranging from mineral and rock identification to the origin of the
continents, from geologic mapping to plate tectonics, and from erosion by rivers
and glaciers to the history of life.

A structural geology
laboratory manual comes always handy to anyone dealing with maps, cross-sections
or stereograhic nets. This manual contains explanations and exercises on
attitude measurements, true and apparent dips, three-point problems,
stereographic projections, rotations with the stereonet, stereograms, geologic
mapping and cross-section construction, thickness and outcrop problems ans
statistical techniques.
The aim of this note is to
provide a basic introduction to the geological and geophysical processes that
form and shape the ocean basins and their margins. Topics covered includes:
Seafloor Mapping, Understanding Conductive Cooling, Cooling of the Ocean Plates,
Evidence for Plate Tectonics from Magnetics, Global Seismology, Mantle Melting
and Phase Diagrams, Mid-Ocean Ridge Segmentation, Subduction Zones, Seismic
Hazards in the Pacific Northwest, Passive Margins and Sediment Transport,
Sequence Stratigraphy and Eustacy, Deep Sea Sedimentation and Paleoceanography.
