recommendations! Published in 2019 at "Geotechnical and Geological Engineering"

DOI: 10.1007/s10706-019-00927-9

Abstract: In western China, red sandstone is widely distributed. This type of rock is susceptible to generate cracks after being disturbed, and thus becomes a communication channel for groundwater, which poses a great hidden danger in… read more here.

recommendations! Published in 2018 at "Earth and Environmental Science Transactions of the Royal Society of Edinburgh"

DOI: 10.1017/s1755691018000968

Abstract: ABSTRACT In Scotland, the base of the Ballagan Formation has traditionally been placed at the first grey mudstone within a contiguous Late Devonian to Carboniferous succession. This convention places the Devonian–Carboniferous boundary within the Old… read more here.
