Topology as a subject, in our opinion, plays a central role in university education. It is not really possible to design courses in differential geometry, mathematical analysis, differential equations, mechanics, functional analysis that correspond to the temporary state of these disciplines without involving topological concepts. Therefore, it is essential to acquaint students with topo logical research methods already in the first university courses. This textbook is one possible version of an introductory course in topo logy and elements of differential geometry, and it absolutely reflects...

Recent discoveries of diamond and coesite in the ultrahigh- pressure (UHP) metamorphosed supracrustal rocks have provoked a new challenge to present-day geodynamic ideas. A worldwide shift towards a new paradigm on the Earth's dynamics is imminent. Facing the new challenge, Chinese geologists have been taking an active role. The Dabieshan-Sulu region, the largest and best exposed UHP belt in the world, has attracted international attention. This comprehensive book describes many aspects of the UHP rocks in the Dabieshan-Sulu region, including the geotectonic setting, mode of occurrence,...

Ever since the oil crisis of 1973, researchers in various fields of chemistry have proposed various schemes to conserve energy, as well to convert the sun's abundant and limitless supply of energy to produce chemical fuels (e. g., hydrogen from water, . . ). The enthusiasm had no previous parallel in the mid-1970's. Unfortunately, despite the several good proposals, the results have proven - in retrospect - somewhat disappointing from an economic viable point of view. The reasons for the meagre results are manyfold not the least of which are the experimental difficulties encountered in...

An Approach to Rights contains fifteen previously published but mostly inaccessible papers that together show the development of one of the more important contemporary theories of the nature, grounds and practical implications of rights. In a long retrospective essay, Carl Wellman explains what he was trying to accomplish in each paper, how far he believes that he succeeded and where he failed. Thus the author provides a critical perspective both on his own theory and on alternative theories from which he borrows, or that he rejects. These essays identify the problems any adequate...

2Gpa has increased to more than 15.
This indicates that subduction of continental fragments to depths of 100-150 km may have played a significant role in the formation of mountain belts.
This volume brings together the geochemical, geophysical and geodynamical approaches to study the processes active during ultrahigh-pressure (UHP) tectonics.
The collection of papers demarkates the frontier of our understanding of the creation, preservation, and exhumation of ultrahigh-pressure rocks.
Audience: This volume will be of interest to any earth scientist interested...

Physicists attempt to reduce natural phenomena to their essential dimensions by means of simplification and approximation and to account for them by defining natural laws. Paradoxically, whilst there is a critical need in geology to reduce the overwhelming field information to its essentials, it often re mains in an over-descriptive state. This prudent attitude of geologists is dictated by the nature of the subjects being consi dered, as it is often difficult to derive the significant parame ters from the raw data. It also follows from the way that geolo gical work is carried out. Geologists...
