Analysis of 53 bulk powders derived from various rocks of the Upper Floridan Aquifer reveal calcite, dolomite/ankerite, quartz, apatite, and smectite to be the dominant minerals, with the clay and apa...
Prior to DSDP Leg 17, no sites drilled in the central Pacific had continuously cored a thick section of pelagic brown clay. On Leg 6 several sites were drilled through brown clay, but poor recovery du...
Real-time, temperature-resolved synchrotron powder X-ray diffraction data and Rietveld refinements provide unprecedented insights into mineral behaviors and mechanisms of crystal structure transformat...
A periodical unevenness of the running surface of rails is formed on ascending slope of submarine railway tunnel. One of the causes has been concluded due to the combination of a low friction and whee...
The leather industry creates a large quantity of organic and inorganic waste containing chromium. This research examines stabilization of particulate tannery waste in type II Portland cement. Several ...
Rietveld refinements using synchrotron powder X-ray diffraction data were used to study the crystal structure and dehydration behavior of pure monoclinic palygorskite samples from Korea and Alaska. Th...
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-...
The Clay Minerals Society maintains a repository of Source Clays to provide scientists and researchers with a readily available supply of consistent materials so that research conducted by different ...
Abstract: X-ray phase analysis of clays is difficult because these materials generally consist of a mixture of different phases, i.e., mixed-layer minerals, individual clay minerals (non mixed-layer),...
Abstract: Selective-dissolution techniques by ammonium oxalate (OX), dithionite-citrate-bicarbonate (DCB), and dithionite-ethylenediaminetetraacetic acid (D-EDTA), and X-ray diffraction and M鰏sbauer s...
Abstract: X-ray diffraction (XRD) profile analysis of eight synthetic hematite samples was performed to identify the best parameters for determining the apparent mean crystallite dimension (D) and, co...
Crystal structures and phase transitions of enstatite (MgSiO ) were studied by in situ X-ray dif-fraction experiments using synchrotron radiation and a multi-anvil high-pressure apparatus at pres-/c t...
Abstract: Clay mineralogical studies by X-ray diffraction performed on extracted <2-祄 fractions do not always represent all clay mineral constituents present in the soil. In this work, transmission X-...
Abstract: A procedure for structural investigations by X-ray diffraction of mixed-layer structures incorporating swelling layers has been developed. For each sample, specimens saturated with different...
Reading the second edition of Moore and Reynolds°OX-ray Dif- fraction and the Identification and Analysis of Clay Minerals is an absolute delight. It is rare to come away from reading a scientific ...
