DOI: 10.1007/s10706-017-0278-9
Abstract: As soft rocks are likely to soften, slime and swell while contacting water, the existence of soft rocks is harmful for stability of surrounding rocks and supporting structures of tunnels. Through uniaxial and triaxial tests… read more here.

DOI: 10.1016/j.marpetgeo.2019.08.016
Abstract: Abstract Global studies suggest that igneous intrusions usually have thermal aureole thicknesses between 30% and 250% of the intrusion thickness. Here, we discuss data and 1D thermal maturity models from nine coreholes (wells) drilled in… read more here.
