A rock mass assessment procedure based on quantitative geophysical log analysis of coal measure sequences
logging, coal mining geotechnical classification
2009/3/5
Geophysical logging is routinely undertaken as part of most coal mine exploration programs. Currently, the main application for the logs is to determine coal seam depth and to qualitatively estimate c...
New sequential separation procedure for Sr, Nd and Pb isotope ratio measurement in geological material using MC-ICP-MS and TIMS
Sr Nd isotope ratio MC-ICP-MS TIMS
2017/8/10
A new 3-step sequential separation chemistry for Sr, Nd and Pb from silicate samples, which is suitable for isotope analysis by MC-ICP-MS as well as TIMS, has been developed. The chemistry is designed...
Randomly Interstratified Kaolinite-Smectite from Galicia (NW Spain): A New Procedure for Determination
Acid Soil Gabbro Interstratified Kaolinite-Smectite Paleohorizons
2011/12/9
Abstract: A new protocol was developed to examine an assemblage of kaolinite-smectite in a buried horizon of a paleosol developed on gabbro parent material. The new extraction procedure appears suitab...
Orthopyroxene from the Serra de Magé meteorite: A structure-refinement procedure for a Pbca phase coexisting with a C2/c exsolved phase
Orthopyroxene Serra de Magé meteorite structure-refinement procedure Pbca phase coexisting C2/c exsolved phase
2012/4/6
AnX-ray structure-refinement procedure wasdeveloped to characterize orthopyroxene from the Serra de Magemeteorite. In the studied sample, the orthorhombic phase coexists with exsolution lamellae of C2...
A Direct Procedure for Determining the Number of Plates in Tactoids of Smectites: The Na/Ca-Montmorillonite Case
Bentonite Conductivity Dispersion Hydraulic Smectite Tactoid
2012/2/10
The dispersion of clays is of great importance in determining various soil properties such as hydraulic conductivity. A procedure which involves fixing followed by embedding of clay particles in an ep...
Kaolinite Intercalation Procedure for All Sizes and Types with X-Ray Diffraction Spacing Distinctive from Other Phyllosilicates
Cesium Dimethylsulfoxide Expansion Hydrazine Intercalation Interlayer Kaolinite
2012/2/10
Kaolinites of all kinds (fine, 乪fireclay,乫 乪type IV,乫 etc.), some of which do not expand or expand incompletely with the usual intercalation methods used for comparison, are expanded completely by tre...
