It is shown that the giant Sikhote-Alin and Pamir deposits of boron are associated with fragments boron-bearing evaporite strata paleoceanic atolls in subduction melange. Ore formation relates both to situ transformation at Ak-Arkhar deposit mobilization redeposition some distance away from source course intensive post-accretionary fluid-magmatic reworking melange Dalnegorskoe deposit.

The main goal of this research work was to detect the different Cu mineralized zones in the Sungun porphyry deposit in NW Iran using the Spectrum-Volume (S-V) fractal modeling based on the sub-surface data for this deposit. This operation was carried out on an estimated Cu block model based on a Fast Fourier Transformation (FFT) using the C++ and MATLAB programing. The S-V log-log plot was gene...

The Baba Ali deposit is located about 39 km to the north west of Hamadan city. The syenitic pluton intruded and metamorphosed the diorite host rock producing the skarn deposit. Geochemical considerations indicate that the concentration values of rare earth elements in the syenite and diorite range from 35.4 to 560 ppm.  Rare earth elements variation in syenitic, skarn and diorite rock are simil...

Ellipsoid or geometric anisotropy is a widely used method in geostatistical analysis to obtain variograms with different ranges directions (azimuth) and relatively similar sill variance. indispensable mining when resource geologist intends understand the spatial continuity of variables related any geological controls mineralization. For example, dealing mineralization tabular deposits, porphyri...

Developments in SQUID-based technology have enabled direct measurement of magnetic tensor data for geophysical exploration. For quantitative interpretation, we introduce 3D regularized inversion for magnetic tensor data. For mineral exploration-scale targets, our model studies show that magnetic tensor data have significantly improved resolution compared to magnetic vector data for the same mod...
