Investigations cover a wide range of geographic and geologic settings that provide different perspectives on this central theme. Below, material is arranged to roughly follow the Wilson Cycle of oceans opening and closing. The material below consists mainly of a series of images from field work and related studies. They are essentially slide shows that represent progress reports in these areas. The images are arranged in a specific order to give an introduction, summary of the geology, and interpretation of each area.
Information provided here is intentionally brief.
Interested readers should see publications and recent abstracts under the web site for Jeffrey Karson or graduate students as indicated. Much of this work has been done in collaboration with Duke graduate students and other investigators whose names are listed as co-authors of corresponding publications. Unless otherwise indicated, the images were produced by J.A. Karson and are not intended for reproduction, publication, etc. without written permission.
