Folks,

When I was doing my thesis work, I ran across some interesting computer
modeling that Crowley (1996) did with applying weather computer modeling
to the Carboniferous.  His climate software used landmass, moutains etc
to project the climates at different times.  He suggested that these
tropical coal swamps existed in a temperate everwet rather than a
tropical everwet (tropical rainforest of today) biome.  He had some
interesting data, but I haven't followed what he has done then or if
that model has since been discarded (I haven't followed paleoclimatet
literature for about 10 years - who can afford Elsevier journals).  Dr.
Pfefferkorn used some of his terminology and would probably know better
what are the current ideas on climate.

Dear Paleonetters,
 
In compiling a study on petroleum source rocks, I have bumped into the
problem of why the large deposits of northern Hemisphere coal are
Carboniferous and why those in the former Gondwana (mostly southern
Hemisphere) are Permian. Is it simply a matter of climate, or are
there
other parameters to be considered?
