DOI: 10.1007/s13202-020-00997-z
Abstract: Understanding spontaneous imbibition helps to determine the fracturing fluid volume and optimize the flowback design. At present, many studies have mainly focused on shale, but few on igneous rocks. As such, in this study, imbibition… read more here.

DOI: 10.1016/j.earscirev.2020.103416
Abstract: Abstract A lithological association comprising high-K calc-alkaline (HKCA) intrusions and shoshonitic volcanics, sometimes with A-type granites, is common along fossil convergent plate boundaries. Although igneous rocks in this association show arc-like geochemical signatures, their genetic… read more here.

DOI: 10.1016/j.gca.2017.09.014
Abstract: Abstract The origin of heavy Fe isotope compositions in high-silica (>70 wt% SiO 2 ) igneous rocks remains a highly controversial topic. Considering that fluid exsolution in eruptive rocks is more straight-forward to constrain than in… read more here.
