Granitic Rocks of Ophiolites
… petrography and chemical composition of granitic rocks (plagiogranites) and associated formations in five ophiolites are described. In addition, the occurrence of similar rocks in other ophiolites, some island arcs and in the ocean crust is reviewed. Plagiogranites in ophiolites can be …

Strength of transversely isotropic rocks
… the failure of transversely isotropic rocks under true triaxial stress states. One major obstacle in formulating an anisotropic criterion is that it usually involves six stress components, instead of three principal stresses. As such, anisotropic criteria usually lead to complicated …

Rocks in the American landscape
At the dawn of history, man used rocks for shelter, defense and places of worship. As he became more advanced, he evolved art forms from rock. In China and Japan rocks were used as sculpture with symbolic meaning over 2000 years ago. The English adapted Oriental ideas on the landscape uses of rocks …

Simulating complex conductivity in carbonate rocks: using digital carbonate rocks and comparison to laboratory measurements
… numerical simulation of physical properties of rocks. This physics-based approach can give important insight into understanding properties of reservoir rocks, and help reveal the link between intrinsic rock properties and macroscopic geophysical responses. Our focus is the simulation of the …

Seismic anisotropy in siliciclastic reservoir rocks
… of the elastic anisotropy of sedimentary rocks in the subsurface. Traditionally, laboratory ultrasonic velocity measurements have been used to provide important information on bulk aggregate seismic anisotropy, however, they do not allow the discrimination of the contribution from the …

Occurance of Selenium in Sedimentary Rocks
<p>The investigation of Selenium in Sedimentary Rocks was stimulated by Mr. Kohanowski who had two samples of sedimentary material that were believed to contain selenium.</p> <p>As not too much information is available or known about selenium minerals Mr. Kohanowski thought it would be educational …

Rocks! (Are Hard To Care For)
Rocks! (Are Hard To Care For) is a character-driven comedy drama about people abruptly shaken out of their taken-for-granted routines and forced to consider what and who it is they really care about in their lives. It is a play about the existential clash between permanence and impermanence, people …

Platinum-group elements geochemistry of felsic rocks
… is poorly understood. The felsic igneous rocks are often linked to hydrothermal Cu-Au mineralization and the presence or absence of sulfide saturation during fractionation is critical to the ore forming processes. PGE can be a sensitive indicator for sulfide saturation due to their high …

Palaeomagnetic studies on some South African rocks
A brief review of the subject of palaeomagnetism as it affects the study of the behaviour of the earth's magnetic field and the problems of Continental Drift and Polar wander is presented, giving the reasons why a systematic palaeomagnetic study of the Cape and Karroo Systems of South Africa would …
