Aeolian Dust and Dust Deposits



In Earth science history, numerous subjects, such as pollen and freshwater diatoms have been studied from first a geological point of view, then in relation to the presentday environment. This is the case for dust; loess deposit studies began as far back as 1880 and included many international publications on the subject, but scientific works concerning the eolian dust only started toward the middle of the 20th century. Nevertheless, investigators of eolian dust have made great strides, as it is pointed out in the interesting book by Kenneth Pye, which puts together the present studies on dust and its history since the Quaternary and Cenozoic epochs. In addition to loess, the studies also cover the contribution of dust to deep-ocean sediments, ice, and soils.
