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 …
A method i:. described for the preparation of trace element reference materials by a co-precipitated gel technique. The technique is applied to the manu- facture of multi-element calibration standards for the analysis of geological materials by direct-reading emission spectrome…
Economic gold deposits may be considered to fall into four classes on the basis of the concentration and precipitation mechanism: (a) primary one-stage hydrothermal extraction. with precipitation in vein conduits or on the sea-floor, (b) hydrothermal leaching of materials which have undergone a prior Au enrichment (multistage)…

Geology, the science of the earth is a fascinating branch of study in Natural Science. It is fascinating because it explains to us the development of topographical scenery on the surface of the land such as the high mountains (the Himalayas, the Alps etc.,) vast plains, volcanoes, waterfalls, grand canyons and coral …
This book is an attempt to provide a textbook in ore geology for second and third year undergraduates which, in these days of inflation, could be retailed at a reasonable price. The outline of the book follows fairly closly the undergraduate course in this subject at lecisester University which has evolved over the last twenty years. It assumes that…
