The whole rock chemical composition obtained by coupling EDS + QXRPD analyses was compared with that obtained by XRF + ICP-MS analysis. A comparison based on correlations between the inferred data provided by Siroquant and actual chemical...

... with the results from a quantitative Greene-Kelly test: 28% and 15%, respectively. Comparison of mineralogical composition results from Siroquant analysis ( Table 1 ) with compositions of reference samples showed that overall there were no major changes in the bulk mineralogy. The positions of d 001...

... Magnetic susceptibilities of some relevant minerals. Traditional methods for quantifying illite content have generally involved whole-rock XRD followed by further XRD of the clay fraction, or have avoided separating the clay by using a method such as the SIROQUANT system ( Taylor 1991...

... of the constituent minerals were performed using SIROQUANT, a Rietveld-type quantitative phase-analysis program ( Taylor and Clapp, 1992 ). Clay was separated from the powdered sample by sedimentation of the coarser fraction through a water column. The supernatant liquid containing suspended clay was pipetted...
