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…

Over the past several decades the philosophy of exploration for oil and gas has pro• gressively changed from drilling on surface seepages to the concept of structural traps, com• plemented later by considerations of sedimentology in relation to the development of reser• voirs, which led to the concept of stratigraphic traps. …
WORLD URANIUM RESOURCES, PRODUCTION AND DEMAND.
Reasonably assured resources of uranium in WOCA (World Outside the Centrally
Plannned Economies Area) countries recoverable at less than US $80/kg U increased by about 9%
between 1983 and 1985 and currently stand at 1.5 million tonnes. Uranium also exists in
si…
In the past, conventional reflection seismic techniques were not very successful when applied to typical mining exploration:They lacked resolution in the shallow range or were not cost effective. By combining a light earth tamper source, special geophones and field procedures, a stacking process of the returning seismic events using a microprocessor…
One of the most important aspects of the interpretation of geochemical data is the choice ofanomaleus values from among these data. Disticuvely anomalous values are readily diseriminated, because they are characterized by statistical methods. Applications of these methods are described in the present paper.
A direct means of indicating the presence of concealed mineralization would be the ultimate in exploration. In many ways the.induced-polarization (IP) technique comes close to achieving this goal. it has been remarkably successful in locating concealed bodies containing even small percentages of metallic-luster minerals.
