Chlorite minerals, found in a great variety of rocks and geological environments, display a
wide range of chemical compositions and a variety of polytypes, which reflect the …

Formation of clay minerals under hydrothermal influence is the result of rock alteration by
circulating hot water in the Earth's crust. A pre-existing rockforming mineral assemblage is …

Two versions of a useful chlorite geothermometer calibrated in the Los Azufres and Salton
Sea geothermal fields have been published. The first applies the linear correlation between …

XMapTools is a MATLAB©-based graphical user interface program for electron microprobe
X-ray image processing, which can be used to estimate the pressure–temperature …

Origin and Mineralogy of Clays, the first of two volumes, lays the groundwork for a thorough
study of clays in the environment. The second volume will deal with environmental …

The evolution of chlorite composition with temperature (and pressure) serves as basis to a
number of chlorite chemical thermometers, for which the oxidation state of iron has been …

We present a new thermodynamic activity-composition model for di-trioctahedral chlorite in
the system FeO–MgO–Al 2 O 3–SiO 2–H 2 O that is based on the Holland–Powell internally …

The chemical composition of about 500 diagenetic chlorites, determined by electron
microprobe, has been studied in six different sedimentary sequences spanning conditions …

▪ Abstract Mixed-layer clay minerals are intermediate products of reactions involving pure
end-member clays. They come from natural environments ranging from surface to low-grade …

The purpose of this study is to derive a solid solution model for aluminous (Si\< 3 apfu)
chlorites encountered in metapelites over a wide range of PT conditions. A compilation of …
