The text files on this web site are chapters in various stages of readiness for a book in preparation (Exploiting the Earth, under contract with Johns Hopkins University Press.)

I have explicitly retained the copyright myself, together with any derivative rights and projects. I have been generating the book in successive versions, as "class notes" in my Geology 115 course at UC Davis. Each successive version has become more "friendly" in contrast with the usual academic presentation, and that conversion to a more general readership continues as I polish the contents.

I am happy for these draft chapters to be read by anyone interested, subject to all the constraints imposed by normal courtesy, copyright laws, and fair usage. In other words, you may copy and print single copies for personal use, but you may not re-post them, pass them off as your work, or sell them.

Any comments would indeed be appreciated.
