I have been following the calcite "sand" posts with interest. George, I
suspect the soils may be more important than you acknowledge. I think it
depends more on residence time and partial pressure (and, of course, plant
activity) than "thickness" of the soils as such.

I have a fresh Austin chalk cave rock ready to go in a vacuum chamber connected
to a mass spec to measure the outgassing, which may give us some data soon.

"As for the origin of the CO2, I think that is still an open question. I'm
not so sure about soils since there isn't much in central Texas. In small
caves it could be organics. But in larger caves, I tend to favor out gassing
from the limestone as it is dissolved by water - especially in caves that

Almost right. The CO2 levels and airflow velocities are essentially
barometrically driven (not chimney effect which requires substantial elevation
differences). In the summer barometric pressure changes are usually small so
little air exchange occurs (and CO2 levels can build). In the winter, fr
