Abstract
Nowadays, exploration management, increasing productivity, and reducing exploration costs are among the most important issues in the detailed exploration stage of orebodies. A geographic information system (GIS) is an effective tool for gathering, storing, analyzing, updating, generating, integrating, and displaying geographic data and land reference. ArcGIS is one of the efficient and powerful GIS computer programs with numerous capabilities such as generating databases, managing the data and information, integrating the information, and generating different outputs in the form of various maps, charts, and tables. In this study, different exploratory layers with different types of information from the Dehshir orebody area were integrated into this software to determine the spread of metal and introduce the parts with higher anomalies for subsurface exploration. For this purpose, we used the information from remote sensing, topography, geomorphology, geology, and geophysics, and geochemistry studies in the form of exploratory layers.
Highlights
Hoy en día, la gestión de la exploración, el aumento de la productividad y la reducción de los costos de exploración se encuentran entre los temas más importantes en la etapa de exploración detallada de los yacimientos
Satellite image processing methods are generally classified into two groups of basic statistics and base spectrum
In base spectrum methods, a specific reference spectral pattern should be available from the beginning of processing, spectral information is still required in interpreting the resulting data as in basic statistical methods
Summary
Satellite image processing methods are generally classified into two groups of basic statistics and base spectrum. Magnetometry is the most common geophysical technique for geological mapping, mineral and oil exploration Access to this information treasure is oriented by the proper processing of raw satellite and processing data. Log Residuals method has been used for radiometric correction to eliminate sunlight, atmospheric scattering, topographic effects, and albedo effects based on the amount of reflection of satellite images (Feizi and Mansouri, 2012). This transfer produces a false reflection image that is useful for analyzing geological features and mineral applications. The software used in this study is ENVI 5.1 and the number of bands used in the ASTER images is 9
