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]

, 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 ...

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

Journal 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.

Aqueously altered igneous rocks sampled on the floor of Jezero crater, Mars

Science, 2022
The Perseverance rover landed in Jezero crater, Mars, to investigate ancient lake and river deposits. We report observations of the crater floor, below the crater’s sedimentary delta, finding that the floor consists of igneous rocks altered by water. The

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

Kuangchan 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

Performance of the X-ray powder diffraction (XRD), X-ray fluorescence (XRF) and the industrial computed tomography used for characterization of the vesicular volcanic rock.

Brazilian Journal of Radiation Sciences, 2021
Volcanic rock is a designation in geology given to extrusive igneous rocks. One type of igneous rock of interest, in economic terms, is vesicular, since, besides the knowledge of the morphology (positioning, size, direction, and interconnectivity of the ...

Prediction of uniaxial compressive strength of rock based on lithology using stacking models

Rock Mechanics Bulletin, 2023
Uniaxial compressive strength (UCS) of rock is an essential parameter in geotechnical engineering. Point load strength (PLS), P-wave velocity, and Schmidt hammer rebound number (SH) are more easily obtained than UCS and are extensively applied for the ...
