Abstract
Soil diffuse CO2 flux (also called soil CO2 efflux or soil respiration) is of interest to a number of research disciplines (e.g. geology, ecosystem ecology, climate and atmospheric science). While ecologists and soil scientists are primarily concerned with near surface, organic carbon flux, geologists are usually interested in CO2 originating from deeper layers associated with magmatism. From the geological perspective, in any survey of CO2 flux a key task is the identification of the biogenic component of the total CO2 flux, so this
