The roots of sedimentology and stratigraphy extend back to the 16 century; however, these disciplines are still growing and changing. Geologists continue to "fine tune" sedimentologic and stratigraphic concepts through a variety of research avenues and by using an array of increasingly sophisticated research tool. The result is a continuous outpouri…
A healthy resurgence of interest in physical geography as a basic, essential ingredient of the American geography curriculum has made itself felt in the near-decade elapsing between publication of the first edition of physical geography and the present revision. We may never return to the early form of environmental determinism, to which reaction wa…
During the past seven years my students and I have approached the problem of seismic deconvolution from many points of view. This book brings together those seven years of work. It is addressed rent audience-practitioners of recursive estimation theory and geophysical signal processors-who, it is hoped, will be drawn closer together by it. Estimatio…
The compilation of a handbook to the Grampian Highlands is a task of considerable complexity because of the wide field of geological subject it has to cover and the fact that, as research workers are still very active in the area, opinions are constantly being modified. While a large measure of agreement has been reached concerning major problems wh…
