Mass changes during hydrothermal alteration, Silver Queen epithermal deposit, Owen Lake, central British Columbia [PDF]
, 1995 A procedure for determining metasomatic norms is developed in this thesis to quantitatively and objectively estimate mineral abundances from lithogeochemical data, The norm calculations use the same principles as do other norms such as CIPW, but the ...

A stable (Li, O) and radiogenic (Sr, Nd) isotope perspective on metasomatic processes in a subducting slab [PDF]
, 2011 Two distinct types of eclogites from the Raspas Complex (Ecuador), which can be distinguished based on petrography and trace element geochemistry, were analyzed for their stable (Li, O) and radiogenic (Sr, Nd) isotope signature to constrain metasomatic ...
