Physical and Chemical Aspects of Granite Weathering in North Central New Brunswick

Abstract

<p>The purpose of this study is to describe the forms produced and processes involved in the weathering of granite in North Central New Brunswick. This is accomplished by the analysis of physical, geochemical and petrographic evidence gathered in the field and laboratory.</p> <p>The field work was done in the summer of 1978 while working for the Geological Survey of Canada under the supervision of C. Gauthier. The study of the granite was of interest because of: (1) The development of unusual granite forms and "deep" accumulation of angular grus in the vicinity of Big Bald Mountain. (2) The development and exposure of a deep (4 m) weathering profile along the south branch of the Nepisiguit River. The presence of these granite weathering profiles and forms are of special significance to the glacial history of the area because their presence may suggest that the area has not been glaciated.</p>
