Detailed stratigraphic study of an area (540 square miles) in the Inner Coastal Plain (landward half) of southeastern Virginia showed that older interpretations of stratigraphic relationships and geologic history based on the terraceformation concept are in error. Study of more than 600 exposures and borings showed that the stratigraphic units are not simple glacialeustatic marine terrace formations which overlie Miocene sediments and areally restricted to one terrace; rather they are composed of both marine and non-marine formations which can be further subdivided into mappable facies underlying several terraces. The term terrace is not used in this study because of its genetic connotation. Purely descriptive terms such as flat, plain and scarp are used to describe morphologic features. (Author).

Detailed geologic mapping subsurface stratigraphic study of post-Miocene sediments east of the Suffolk Scarp and Nansemond River in southeastern Virginia show that older morphostratigraphic concepts are erroneous. Instead of two 'terraces', with one 'terraceformation' of offshore marine origin beneath each, a complex of formations is present, in some cases with three to five formations underlying a single flat area previously designated a 'terrace'. The present study revises earlier work based on inadequate stratigraphic information, and thereby serves as a stratigraphic basis for future Atlantic Coastal Plain studies of post-Miocene sediments east of the Suffolk Scarp.

The book is structured thematically, encompassing principles, processes and products, practice and applications. Discussion of processes that control heavy mineral assemblages throughout the rock cycle are presented by leading experts, whose key-note works are followed by specialist case studies. Each work also provides details on the geology of the study area, techniques and data treatment. The high number of contributions represent the collective experience and wisdom of generations of geologists, and provide an invaluable source of references to works carried out in many parts of the world. * Presents a unique and authoritative resource of immediate relevance and practical use to the researcher and applied geologist * Contains case studies demonstrating the broad range of applications of heavy minerals in a variety of modern and ancient geological settings, and in resource exploration * Includes examples of geological problems from employing heavy mineral analysis and establishing criteria that can be applied before deciding to undertake a study
