The paleotopography reconstruction of orogen has an important research value on the study of mountain building and the study of orogen’s regional control over the paleoclimate change. Considering the ...
The affinities of the selachian genus Ptychodus is discussed and Hemiptychodus is here re-introduced as a subgenus characterized by unusual tooth ornamentation pattern.An overview ofAsian hybodont gen...
The Gildirli Formation is the oldest Neogene rock unit in the Adana Basin and was formed prior to the regionally extensive Early Miocene marine transgression. These coarse clastic red-beds provide imp...
Abstract: The clay particles in a kaolin deposit from Brazil were investigated by X-ray diffraction (XRD), differential thermal analysis (DTA), analytical transmission electron microscopy (ATEM), and ...
Quartz°(TM)one of the most abundant minerals in the Earth°Os crust°(TM)has been deemed a human c cinogen by the International Agency for Research on Cancer (IARC), with the main threat to humans bei...
This study clarifies the crystal structure variations and relationships in the zeolites eri-onite and offretite. The crystal structure analyses used Rietveld analysis of X-ray powder diffraction data,...
Cu3(As,Sb)S4 minerals commonly contain structurally disordered crystals of intergrown enargite and the luzonite-famatinite series (Po?sfai and Sundberg 1998). Here we discuss the relationships between...

Abstract: A new model for the interpretation of dioctahedral mica infrared (IR) spectra in the OH stretching vibration region is proposed. It is based on the analysis of the main factors responsible f...
Abstract: A large and representative collection of clay-size dioctahedral mica minerals differing in their chemical compositions has been studied by infrared (IR) spectroscopy in the OH stretching vib...
Abstract: This paper deals with the use of Stern theory as applied to a clay-water electrolyte system, which is more realistic to understand the force system at micro level than the Gouy-Chapman theor...
Experiments on tonalite and granodiorite wereperformed at conditions ranging from 2.1 to 18kbar and 550 to 850°C to establish the magmatic stability field ofepidote as a function ofP, T,and f02. Atwat...
Raman and Fourier-transformed infrared spectra of natural trioctahedral chlorites of polytype IIb were obtained for a series of samples characterized by distinct Fe/(Fe + Mg) and Si/Al ratios ranging,...
Hypothetical model structures for magadiite and sodium octosilicate, based on the structure of the zeolite dachiardite, are proposed that consist of layers of 6-member rings of tetrahedra and blocks c...
A kaolinite-rich bed (tonstein) and an associated bentonite in the upper part of Yegua Formation at College Station, east-central Texas, were formed by in situ weathering processes in a late Eocene sw...
