Residual air in air/brine systems

This sample was cored in a block of quarry sandstone from Boise, Idaho (USA). Boise sandstone contains a significant fraction of feldspar, mica and clay materials. A porosity of about 0.28 was estimated by Helium pycnometry and a mean pore-throat diameter of 31 µm was estimated by MICP measurement.
