Abstract

Weathering extends to shallower depths on diabase than granite ridgetops despite similar climate and geomorphological regimes of despite similar climate and geomorphological regimes of denudation in the Virginia (USA) piedmont. Deeper weathering has been attributed to advective transport of solutes in granitic rock compared to diffusive transport in diabase. We use neutron scattering (NS) technique to quantify the total and connected sub-millimeter porosity (1nm
