Abstract :
lonometric method for mineral deposits exploration was introduced by S. V. Grigorian in 1985. The method is based on the detecting of the ions where is emitted above the buried deposits of ore bodies in the near- ground atmosphere, The ionometric anomalies over the ore deposit, are detected by the concentration of ions in a receiver which is filled with electrolyte and closed by a special membrane.
Chemical elements concentrations in electrolyte are determined by different analytical methods such as polarographic, atomic - absorption and emission spectoral.
Despite the differences in geological conditions, most of ore bodies and their differing levels of hidling, or covering with sediments, varies in composition, age and thickness, These are detected by distinct ionometric anomalies of typomorphic indicator elements.
Several ore deposits such as gold, copper- nichel, copper- pyrite polymetalic, sulfur, diamond- beaning Kimberlite were investigated by this method.
The results of ionometric studies of the halos show that a direct correspondence exists between the ionometric anomaly compositions and ore bodies in different Kinds of ore deposits. Thus, the investigation of ore deposits by the lonometric method gives us the opportunity to explore any hidden ore bodies without relating them to the covered sediments or even the host rocks.
ft is possible to investigate the buried and blind depasits by the ionometric method at a depth of 300 to 400 m or even up to 1000 m, where ore is covered by alluvial deposits or independent sedimentary rocks. Obviously there are many ore deposits where covered or buried by the Quaternary sediments and alluvial fans or peidmont alluvial plain in the internal mountain basins. These are specially in the desert environment which are not detectable by the usual methods, such as, geophysical or geochemical, methods but the ionometric method made them plausible
