A geologic and mineral resource assessment of Indonesia
This paper presents an assessment of all undiscovered mineral resources in Indonesia by province. In addition to hydrocarbon, study results indicate that Indonesia may be well-endowed in nonfuel mineral resources, particularly in Timor, Nusa
The significance of various sediment magnetic mineral fractions for tracing sediment sources in Killimicat Creek
Australia ; Confluent ; Heavy minerals ; Magnetic susceptibility ; New South Wales ; Sediment load ; Sedimentology ; Tracer ; Watershed
This paper reports on experiments to measure the relative contributions of the magnetic constituents of sediments. The proportionate contributions of heavy and light mineral components of two different sediment streams delivered to the confluence
in the headwaters of Killimicat Creek, New South Wales, are determined from mineral magnetic measurements. The results show that most of the magnetic mineral component is associated with sediment particles, rather than the discrete heavy mineral component.

This chapter provides a brief overview of the major Fe minerals occurring in earth surface environments where organisms are likely to participate in mineral formation. Microbiological activity is known to cause both the dissolution
and the precipitation of Fe minerals. Examples illustrate the diverse interactions between the formation of Fe minerals and the biosphere, the results of which are frequently manifested in colorful soils and sediments around the world.
Analysis of clay minerals in Hungarian loesses on the basis of the clay mineral map of soils in Hungary in Loess and the Quaternary: Chinese and Hungarian case studies.
The clay mineral map of soils presented data to analyze the regional composition of loesses. The amount of chlorite increases in the Alpine region, while the ration of smectites grows in the vicinity of andesitic mountains and in the margins
Mineralne vody Zvolenskej kotliny. (Mineral waters in the Zvolen Basin)
An information of the occurrence, distribution and geochemical characteristics of the individual types of mineral waters in the Zvolen Basin. This basin of Middle Slovakia is rich in mineral waters among them are several evaluated as drinking table

Strontium isotopes as indicators of mineral weathering in catchments
The purpose of this paper is to report the 87Sr/86Sr ratios in rain-water, stream-water, soils and rocks in two Scottish catchments and to relate these data to mineral weathering in the soils as the first stage in a more detailed study being carried
out in the use of strontium isotopes in mineral weathering studies.
The AA. describe the types and forms of iron sulfide minerals in magnetotactic bacteria and their possible biogeochemical and palaeomagnetic significance.
Uusiutumattomien luonnonvarojen tuotannon alueelliset erot maapallolla. (Regional differences in the exploitation of mineral resources in the world)
The average exploitation of 22 types of mineral resources in the various countries of the world is studied over the three-year period 1978-1980 (1979-1981 for the fuels) and the contribution of each country to the world production of each mineral
Clay minerals from the loess-paleosol section at Baoji in north-central China were studied by X-ray Diffraction. The purpose here is to identify clay mineral variability and trends in the loess-paleosol record, and interpret their paleoclimatic
