Residual soil is one of most widely employed sampling materials for tracing geochemical anomalies in geochemical exploration. Systematic studies on the phenomenon of the formation of geochemical anomalies in residual soils are being carried out by the Geolo…

In this short Course the main emphasis will be on the methods by which geo• chemists select and analyse accessible Earth materials, the relationships between the chemical composition and the structure of rocks and minerals, the chemical aspects of the Earth's structural evolution, geochemical reactions and cycles, and the p…
In the framework of an expedition with a limited duration only a small number of aspects of the extremely complicated coral reef biology and geology can be studied and only a small number of the numerous coral reef areas of Eastern Indonesia can be investigated. Consequently a choice has been made, based on an identifi…

The ever increasing availability of computer programs and facilities leaves no question that a geologist can perform a factor analysis with little difficulty. Be cause of this ease, there is often a tendency to apply methods without fully understanding either the logic of the method or the …
The field programme for the year 1961 and following years is mainly based on:
1. the need of counterparts for the foreigmn experts in the execution of geological explorations for the purpose of different "foreign aid projects".
2. The need of carrying out the "home projects", which is scheduled mainly during the wet season
3. the need of continuing …

The discovery of the- negative belt of gravity anomalies along the trenches in Indonesia by Vening Meinesz has awakened geologists and geophysicists to developing ideas of,the formation of island arc systems and mountain building processes. The modern tectonics which is still, according to the author, a hypothesis should be proved, although s~e g…
