In general, we may think of minerals as the materials of which the rocks of the earth's crust are made, and, as such, minerals constitute the most important physical and tangible link with the earth's history. The mineralogist regards the minerals he finds in rocks and veins as the stable end products of a complex of natural processes which it is hi…
In this volume we have included all papers which were presented at the Conference which are of clear interest and concern to specialists in the region. In ordering the papers in the proceedings we have grouped the general papers under a series of subject headings, and included the national papers on a country by country basis. Thus, the four ASEAN c…
Each the student develops a personal style in the use of a text. Whatever your own approach, you will find that we have incorporated a number of features which will help you in your study of physical geology. Some of these features bear mention here. There are many possible arrangements of material that can be used in presenting a first course in ph…

The IAMG session at SEDIM NICE (the 9th) was the second one held in conjunction with an IAS Congress - the first was at Heidelberg (the 8th) in 1971. Because sedimentologists were among the first in the earth sciences to use numbers in their analyses, it is appropriate that periodecally reports be given on the use of statistics, mathematics, and com…
The magnetotelluric method is a geophysical technique which provides information about the deep electrical conduktivity distribution within the earth beneath the site of the surface field measurements. This method responds to one of the basic physical properties of rocks and minerals-conductivity, which in most rocks, is determined by the path of io…
Metamorphic petrology is at present undergoing a change in emphasis. For the past two decades, metamorphic processes have been considered largely in terms of mineralogical and chemical changes and many petrologists have been so preoccupied with experimental synthesis and the determination of the physical conditions under which minerals or mineral as…
The contributions were sent to the organizing commitee of the symposium in february and March 1974 and were prepared for print in a very short period. for this reason only minimum editorial changes in the text and the most necessary linguistic corrections could be made by the organizing committee.

However, since very little has been published officially, not much is known something about mining in Indonesia must depend on second and third-hand information of questionable reliability. When indonesia in 1967 invited foreign participation…
Since then applied environmental geochemistry has grown enormously to encompass the many factors influencing the sources, dispersion and distribution of elements in the environment, their pathways into foodstuffs and water supplies, and possible effects on health and disease in plants, animals and man. The multi-disciplinary and international nature…
