Spontaneous imbibition in igneous rocks: effect of KCl concentration, confining pressure, and imbibition direction

open access: yesJournal of Petroleum Exploration and Production Technology, 2020
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.

Trace element and isotope constraints on crustal anatexis by upwelling mantle melts in the North Atlantic Igneous Province: an example form the Isle of Rum, NW Scotland [PDF]

open access: yes, 2009
Sr and Nd isotope ratios, together with lithophile trace elements, have been measured in a representative set of igneous rocks and Lewisian gneisses from the Isle of Rum in order to unravel the petrogenesis of the felsic rocks that erupted in the early ...

Petrographical and Mineralogical Characteristics of Bengge Alkaline Igneous Complex in Zhongdian, Western Yunnan and Its Geological Significance

open access: yesKuangchan zonghe liyong, 2022
Bengge alkaline igneous complex in Zhongdian, Western Yunnan has the variety of rock types, which is production after a complex magma—fluid process. The petrographical and mineralogical analysis of the host rock and its xenolith suggests that the igneous

Large Igneous Province Record Through Time and Implications for Secular Environmental Changes and Geological Time‐Scale Boundaries

open access: yesGeophysical Monograph Series, Page 1-26., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.
