Principles geochemical

Postdepositional changes can obscure the sedimentary paleoceanographic record. Fortunately, these alterations follow predictable geochemical principles, making it...

It is useful to examine metal phosphate geochemical principles and behaviour in perturbed natural systems to elucidate the role of phosphate in sequestering metals. Early research efforts... 

The broad scope and diverse nature of the chapters in this volume made the process of dividing them into sections or subject areas somewhat difficult. Many chapters relate to more than one section. The common methods of subject classification according to fuel type (petroleum, natural gas, coal, etc.) was intentionally avoided so as to emphasize geochemical principles and controls that have common chemistry for all fuel types.

The timeliness of this symposium has increased in importance as the world has focused a great deal of attention on the causes of the degradation of the atmosphere and hydrosphere. We hope that works contained in this volume will lead to a better understanding of aqueous environmental chemistry and the importance of properly using geochemical principles to solve these and other geologic and hydrologic problems.

This paper provides a general review of exploration methods for major types of uranium deposits. The author has been active in exploration for deposits hosted by rocks of Precambrian, Palaeozoic, Mesozoic and Caenozoic age. Much of this work involved deposits in sandstones, but the geochemical principles also apply to many of the Precambrian deposits. 

In the rural situation, the total trace-element content of the soil may be virtually the same as that of the rocks from which the soil parent material was derived by weathering. The geochemical principles controlling the trace-element content of uncontaminated soils have been reviewed and reported by Mitchell [5, 80] who stated that it is possible to assess, with some degree of accuracy, the approximate total content of trace elements in a soil, when the nature of the parent material is known.
