This report focuses much on regional geochemistry as a system for mapping of the secondary environment. The reasons for this are that geochemistry has during the past decade found applications far beyond the traditional ones in the search for mineral commodities. The fields that applied-- geochemistry currently finds applications to are primarily:
*…
Orientation studies indicate that stream-sediment geochemistry is a potentially useful exploration tec~ique in the Kepala Burung region of Irian Jaya, Indonesia. Previously located uranium anomalies and small zones of known base-metal sulphide. mineralisation, are reflected in anomalous concen• trations of these elements in•the stream sedim…
The book summarizes the occurrence, geochemistry, mineralogy, petrology and phaseequilibria studies in air and under high pressures related to the most intriguing group of potassium-rich mafic and ultramafic rocks, often including host of exoyic mineral assemblages including feldspathoids.
Land-water interaction in the Malili Lakes area can be explained by a external and internal scales. The first is expressed as surface water flows while the second is the underground ecotones, in the soil, cracks, joints, fractures, and caves along the boundary zone between high and low groundwater table. A clear and sharp boundary between the two…
The recognition of the nature of primary and secondary dispersion halos and trains associated with mineral deposits. Although haloesand trains were known for centuries to be associated with metal deposits, the work carried out in the U.S.S.R and Scandinavia in the 1930's and early 1940's systematised the data and permitted it to be used in the most …
The Purpose of this secction is to describe those aspects of the evolution of the Australian landscape and of the present environment that are important to the understanding of geochemical dispersion. Parts of the landscape are the result of over 250 m.y. of subaerial exposure. Permian glaciation allowed a"fresh start" to landscape evolution in much…
Enormous advances have been made, and a phenomenal increase in available data has occurred, in the field of expliration geochemistry in the past two decades. The pace has been so fast that it has been largely impossible too keep abreast of new developments and the expanding data base. EVEN MORE CRITICAL, MANY OF THOSE WHO HAVE entered the field rece…
