One thought on “Q: What are the systematic processes for searching for mineral deposits by narrowing down areas of promising enhanced mineral potential?”
Since it involves various stages they have been discussed in brief. By locating the obvious geological potential zones from the regional to local geological maps for economic mineral deposits and demarcate the target areas for exploration.
Having identified the target area, 1. It is necessary to identify any detailed geological maps are available for that area, if not perform detailed geological mapping on 1:2000 or 1:1000 scales and delineate geological set up and geological / structural control of mineralization. 2. Try to Understand the mode of occurrence and nature of mineralization by field, petrography and ore microscopic techniques and finalise the required orientation of survey. 3. By identifying the geochemical anomaly zones for different minerals through aerogeophysical survey prognosticated maps and pedo-geochemical soil-bedrock sample analysis map, we narrow down to the zone of interest.4. By analyzing any subsurface anomaly data through geophysical survey or scout drilling at different levels, the zone of interest can be located. 5.By applying different techniques of ore reserve estimation for different minerals of varying geological set up, the resource and reserves or ore/mineral are computed and substantiated with the 3D models generated to establish and categorise the mineral potentiality of that terrain.
By this systematic approach and orientation survey, understanding the nature of mode of occurrence of ore/mineral assemblages, it can be narrow down to the promising enhanced mineral potential zones and achieve the target.
