Provenance, transport and deposition of Rhine sediments : a heavy mineral study on river sands from the drainage area of the Rhine

The starting point of this investigation has been a study of transport and deposition of Rhine sediments. The mineralogical investigation, devised originally as a preliminary study of the source of the sediments, has acquired such importance that separate treatment became necessary. Main problems are the source of the minerals, the relation between grain size and mineralogical composition of samples, the influence of abrasion on heavy minerals and the way of mixing of supplied associations. In the second part methods of sampling, mechanical analysis, heavy mineral separation and fraction analysis of the heavy residue are discussed. ... Zie: Summary
