Petrology of the Sedimentary Rocks

[Book]

by J. T. Greensmith.

Seventh Edition

Dordrecht Springer Netherlands

1988

In the 75 years of the existence of this book the content and boundaries of sedimentary petrology have increased enormously. It is doubtful if there are any areas of the subject described by the original authors which have remained untouched by the relatively recent onslaught by countless sedimentologists, aided by a veritable armoury of sophisticated techniques. Particular areas have always waxed and waned in popularity and some subjects, such as heavy mineral studies which have been successively popular, then unpopular, appear of late to have had a new lease on life. The development and application of relatively old techniques, but now used in a sedimentological context, often brings an upsurge and revival of interest in some rocks. Isotope work has now become an integral part of the study of pelagic and phosphatic sediments, and carbonate cements. An understanding of burial diagenesis, a much neglected area, is slowly coming to the fore as electron microscopes and X-rays delve into the mineralogical and textural complexities of ancient sediments. Yet, despite the 'zapping' of minerals with electron beams and generating gases to pass into a mass spectrometer, to paraphrase an erstwhile research student of mine, the danger of this approach is that materials are analysed with scant regard to field relationships or petrographic control, thus much genetic information is missing when interpretations are attempted. Petrography is far from being archaic.
