The current state of the art of several aspects of minerals and petroleum is presented in this volume. It documents the proceedings of the Internationl symposium on Particle Technology and Surface Phenomena in Minerals and Petroleum sponsored by the Fine Particle Society (FPS). This meeting was held in San Diego, California, August 21-25, 1990. The symposium upon which this volume is based was organized in five sessions emphasizing various basic and applied aspects of research on minerals and petroleum technology. Major topics discussed involve surface phenomena in minerals, mineral flotation, characterization of aspaltenes, theoretical aspects of reservoir simulation, porosity, permeability, residual water saturation, hydrocarbon and gas potential in north slope Alaska, polymer/alkaline flooding, surfactant flooding and foam flooding for enhanced oil recovery. This edition includes eighteen selected papers presented in the symposium. These papers are divided in four broad categories: (1) Asphaltene Aggregation and Characterization, (2) Theoretical Aspects and Reservoir Characterization, (3) Colloidal Dispersions in Minerals/Petroleum, and (4) Surface Phenomena and Petroleum Recovery. Several mineral and oil recovery processes using various chemicals with special reference to surface phenomena and particle technology are described in these sections.

From a general point of view the importance of striving to minimize envir- mental disturbances on the continental shelf cannot be overemphasized. Coastal areas are sites of population centers, navigation and recreation activities, and - source development, all of which contribute to environmental stress on the shelf. Proper management of the shelf for optimum use requires a thorough understanding of shelf processes. Complex problems, such as the influence of hydrodynamics on sediment dispersal, element differentiation and migration, physiochemical changes at the sediment water interface, the relationship - tween the pollutants and sediments, and the type of substrate with regard to benthic community and/or man-made structures require a multidisciplinary approach to their solution. The present study interrelates meteorologic, hyd- graphic, sedimentologic, and geochemical parameters to derme specific envir- ments on the Alaskan Shelf. These observations are then related to geologic principles in an effort to elucidate the sedimentary processes and elemental migration on the shelf. Attempts have also been made to relate the sediment texture to the geochem- try of the sediments. Obviously the chemistry is complicated as a result of b- genic contributions and variable provenance; however, to some extent elemental differentiation accompanies textural differentiation in sediments. The distribution of elements in various phases of crustal (source) rocks is gen- ally interpreted on the basis of crystallographic concepts, especially the concept of isomorphism.

Of all the Rajput states of Rajasthan, Marwar represents the best model for understanding Rajput polity within the perspective of the rise and fall of the Mughal empire. The present study seeks to take a fresh look at the politico-administrative structure in this princely state during the Mughal period.Based on contemporary documents and records, it traces the historical evolution of this structure and the forces which helped to shape it. The various aspects of Marwar polity such as the role of the nobility, its organization and composition, nature of changes in the institutional structure caused due to external and internal factors and the sources of state revenue have been critically examined. Special emphasis has been given to the economic foundation of this institutional framework, particularly the land?revenue.The author has also discussed the political activities of the Rathor rulers and their relations with the Mughal emperors vis-à-vis the rulers of the neighbouring states. These constituted a part of the milieu in which the institutional structure evolved and the changes therein took place.The author has retained the social, economic and administrative terms in their original form. Since words produce a particular image of the reality they are employed to describe, an analysis of the contemporary connotation of these terms has also been made. These terms and the discussion on them further broaden our understanding of the system.
