Clay minerals of calcareous sedimentary rocks of south (Fars and Kuhgiluyeh Boyerahmad Provinces) and western Iran (Kurdestan Province) as a part of the old Tethys area were investigated in order to c...
A method of ultrasonic leaching has been developed for the destructive analysis of magmatic rock samples1. This method was applied to determine three new elements, Ca, Mg and Al, in magmatic rock samp...
Determination of Manganese and Iron in Magmatic Rocks After Ultrasonic Leaching by flame AAS.
Abstract: An internal standard X-ray diffraction (XRD) analysis technique permits reproducible and accurate calculation of the mineral contents of rocks, including the major clay mineral families: Fe-...
Abstract: Clay mineral diagenesis in the Niigata basin is documented by mineralogical and chemical analysis of clay minerals from cuttings from the Shinkumoide SK-1D (SSK-1D) well which is characteriz...
Abstract: The clay mineral textures, assemblages, formation mechanisms, and controlling geological parameters relating to alteration of silicic volcanic rocks by hydrothermal solutions, in core sample...
Abstract: To characterize the evolution of dioctahedral interstratified clay minerals in the Golden Cross epithermal deposit, New Zealand, hydrothermally altered volcanic rocks containing the sequence...
Abstract: Mining operations during the early 1990s at Uley Graphite Mine near Port Lincoln on southern Eyre Peninsula, South Australia, uncovered abundant nontronite veins in deeply weathered granulit...
Abstract: This study examines the evolution of the texture, structure, and chemical composition of rocks derived from clastic materials of the Ossa-Morena Zone (Hesperian Massif, Spain). Previous stud...
This book traces in detail the developments in igneous pe- trology of the theory of crystallization-differentiation as es- poused by N.L. Bowen, whose overarching genius generated a revolution in t...
Oxygen isotope thermometry based on fractionations among quartz, garnet, kyanite, silliman- ite, and potassium feldspar in amphibolite to granulite facies schists and gneisses was compared to thermo...
Abstract: Many soils developed from volcanic rocks in southern Brazil exhibit spontaneous magnetization caused by the presence of fine-grained maghemite (γ-Fe2O3), but few attempts were made to quanti...
The controversies surrounding granites never seem to die. Two hundred years ago a debate raged over whether granites are sedimentary or igneous. With James Hutton effectively putting that one to re...
A new consideration of oxygen isotope resetting among metamorphic minerals is made account- -buffering by typical mineral assemblages during cooling and (2) ing for (1) the possibility of f experim...
Ultrahigh-pressure (UHP) minerals of the Maowu mafic-ultramafic complex in the Dabieshan, east-central China exhibit many exsolution textures. Magnetite lamellae are common in olivines and Ti clinoh...
