Figure 3, modified from KRTA (1989), shows the Ulumbu geothermal area and its location relative to Ruteng, Heng, Ponggeok and W Kokor. As indiated earlier a reasonable • amount of surface scientificsurvey work has been completed. However, one of the technical philosophies. under…
An aapa mire was investigated peat geologically. Based on about 1500 volumentric peat samples, the depth, peat types, degree of decomposition (V. Post's methods), bulk density, water content and shear strength were examined along an 800 m transcet. The calorific value was determined from 58 respresentative peat samples from the same transect, as wel…
Metallogenetic concept on mineral deposits of Indonesia as proposed by WESTERVELD is reviewed.
Depsite its general validity and practical applicability, certain geological phenomena and mineral occurrences seem to contradict the concept and therefore revisions are suggested A Metallic mineral distribution map with a scale 1:5000.000 accompanies thi…
Fundamental questions of metallogenetic investigations are first donsidered. The difference betwen factors and indicators in metallogenetic analysis is discuss.Metallogenetic factors are geological phenomena which condition the formation of deposits.They are its cause.
We are living in an epoch when numerous secrets of nature are being discovered and natural resources are being reclaimed by humans. At the same time, however, this is an epoch of considerable human efforts to protect their health against an increasingly destructive anthropogenic acti…
This practical step by step guide describes the key geological field techniques needed by today's exploration geologists involved in the search for metallic mineral deposits. The techniques described are fundamentals to the collection, storage and presentation of geological data and their use to locate ore. This book explains the various tasks which…
