10 Sep The Charge Of Component Layers Of Illite-Smectite In Bentonites And The Nature Of End-Member Illite
The nature of component layers of mixed-layer illite-smectite and their possible evolution in the course of illitization have been debated since the 1960s. The present study is a new attempt to solve these problems, using samples collected from diverse geological formations around the world. ...
15 Aug On The Problems Of Total Specific Surface Area And Cation Exchange Capacity Measurements In Organic Rich Sedimentary Rocks
The increasing exploration and exploitation of hydrocarbon resources hosted by oil and gas shales demands the correct measurement of certain properties of sedimentary rocks rich in organic matter (OM). Two essential properties of OM-rich shales, the total specific surface area (TSSA) and cation exchange capacity...
23 Jul Surface Area And Layer Charge Of Smectite From CEC And EGME/H2O-Retention Measurements
The total specific surface area (TSSA) and smectitic layer charge (Qs) calculated from the structural formulae and unit-cell dimensions of 12 pure smectite samples were used as a reference in the design and evaluation of TSSA and Qs measurement techniques based on cation exchange capacity...
