----------------------------Original message---------------------------- I need help locating some specific maps. As will soon become evident, I am not a map person so my description of what I want may not be very clear. What is needed is a set of maps or an atlas that shows outlines of sedimentary basins - for the whole world. We found one map that seem to provide the kind of info needed in the way it was needed. That map was: Geologic framework, petroleum potential and field locations of the sedimentary basins in China. This is a USGS misc. investigation map, I-1952. What I'd like to know is if anyone can suggest a source or a volume that would have similar maps/information for the whole world. We've come across a single wall map from AAPG that contains the sort of information needed but it wasn't detailed enough. Thanks for any help you can provide.
