new structural, metamorphic, finite strain and kinematic vorticity data for granitic gneiss and metavolcano-sedimentary rocks of thetanumaharea in the arabian shield in saudi arabia reveal a history of deformation reflecting different tectonic regimes. kinematic analysis shows their relationship to the nappe contacts between the granitic gneiss and metavolcano-sedimentary rocks and explains the...

In this paper, based on the gneiss outcrop of Bozhong 196 gas field in China, uniaxial compression and Brazil splitting tests were conducted by using cores different orientations. The following properties studied: elastic modulus, Poisson’s ratio compressive strength outcrop. tensile peak energy rate results demonstrate following: (1) strength, specimens with horizontal core-taking are greater ...

Abstract Recent studies conducted in the context of geological disposal spent nuclear fuel low-porosity crystalline bedrock have found density and porosity values obtained following ISRM Suggested Method (ISRM 1977) to occasionally be sporadic. To investigate this behaviour, 137 core specimens 5 different rock types (granite, granitic pegmatoid, veined gneiss, mica gneiss sandstone) were submer...

Boron isotope compositions were measured in kornerupine and tourmaline from lenses consisting primarily of kornerupine, plagioclase corundum. The occur within hornblende-gneiss or along the boundary between this gneiss an amphibolite lens at Akarui Point Lützow-Holm Complex, Prince Olav Coast, East Antarctica. peak metamorphic conditions have been estimated to be ~ 800-900 oC 8-11 kbar. δ11B wh...
