Possibilities and restrictions of heavy-mineral analysis for the reconstruction of sedimentary environments and source areas
The possible reconstruction of ancient sedimentary environments on the basis of heavy-minerals assemblages is presented by means of discriminant lithogeodynamic diagrams that compare modern and ancient sedimentary environments. This is exemplified by Mesozoic-Cenozoic deposits recovered from ODP cor...
