The Tourmaline Group in Sediments

Paul D. Krynine

Open publisher page 126 citations

Abstract

Tourmaline is really a complex isomorphous mineral group which can be easily differentiated under the microscope into a series of varieties and types. These types are based upon the recognition of five main sources of tourmaline in sediments: granitic, pegmatitic, metamorphic injected, sedimentary authigenic, and reworked sedimentary detrital. Actual examples of the application of these concepts to the solution of problems of correlation, interpretation, and differentiation of sediments and to the reconstruction of paleogeographic conditions are given.
