Seismic anisotropy in siliciclastic reservoir rocks [PDF]
, 2006 The interpretation of geophysical field measurements of seismic anisotropy is presently limited by our knowledge of the controls of the elastic anisotropy of sedimentary rocks in the subsurface. Traditionally, laboratory ultrasonic velocity measurements

Timing of deposition, orogenesis and glaciation within the Dalradian rocks of Scotland: constraints from U-Pb zircon ages [PDF]
, 2002 The stratigraphical and structural continuity of the Late Proterozoic Dalradian rocks of the Scottish Highlands is re-examined in the light of new U-Pb zircon ages on the tuffs belonging to the Tayvallich Volcanic Formation (601 ñ 4 Ma), and on the late ...

Zinc Contents of Mafic Micerals in Granitic Rocks, with Special Reference to Ore Chemistry [PDF]
, 2003 In order to know the reason why the Cu/Zn-Pb ratios of skarn-type deposits related with the ilmenite-series granitic rocks are markedly higher than those related with the magnetite-series, comparative mineralogical studies were carried out for the two ...

EFFECT OF CALCIUM CARBONATE CONTENT ON THE SURFACE VOLTAGE GENERATED BY ROCKS [PDF]
Journal of the Egyptian Society of Tribology, 2023 When two materials come into contact with one another, it is known that charges could be transferred from one surface to the other. This phenomenon is known as the triboelectric effect.
