ry any standard book on petroleum geology written in the last 30 years. For example:

Hobson, G. D. and Tiratsoo, E. N. 1975. Introduction to petroleum geology. Beaconsfield, England

Huc, A. Y. 1990 (ed.). Deposition of organic facies. AAPG Studies in Geology No. 30.

Katz, B. J. 1995 (ed.). Petroleum source rocks. Springer-Verlag, Berlin

North, F. K. 1985. Petroleum Geology. Allen & Unwin, Boston

Selley, R. C. 1998. Elements of petroleum geology. Academic Press, San Diego

The web is a poor guide. There are lots of good petroleum geology web sites, especially course notes, However, because of the
attraction of woo-woo ideas, the abiotic theory is grossly over-represented overall.
