New Instruments

Innovation in the 1980s and 1990s has been dominated by new instrumentation. Only recently has processing and interpretation technology appeared which will extract the maximum value from the new instruments. In the following sections, the instrumentation advances are outlined. Processing and interpretation advances are sketched in the last section.

Brown Coals

The results of experimental research of the native gold distribution in the coal combustion products (CCP) obtained out of the brown coals of the Yerkovetskoye deposit combustion material in the experimental technological complex “Amur” (ETС “Amur”) are described in the article. The technology of the formation of slag, fly ash and products of wet cleaning of flue gases in the process of various combustion modes of coal combustion is examined. The possibility of the obtaining of enriched gold-containing concentrate by gravity and magnetic methods from the brown coal combustion products and extraction of native gold out of the concentrate is shown.

Basin Area

Integration of gravity, magnetic, resistivity and geophysical well logging methods were used to reveal the geological structures and the hydrogeological conditions. Magnetic mineralogy among the primary bed rocks or within the sedimentary sequence considerably affect the responses of gravity and magnetic methods. En Nuhud Basin is structural depression as a half-graben produced by displacement along a system of faults. Gravity measurements give a sense of that the area was dissected by different fault trends of NNW-SSE and E-W trends, with down throws towards the center of the basin, and variable magnitudes of displacement. The thickness of the sediments occupying the basin vary from few meters at the periphery of the basin to about 1000 meters at the southern parts. The water saturated zones in the Nubian Formation show good characteristics and a thickness range from 12- 140 m. The weathered Basement Complex is sometimes serve as aguiferous zone.
