The integration of the Spectral Gamma Ray (SGR) data with sedimentary rock geochemical data has been used effectively for both carbonate and clastic rocks. This integration provides

considerably more information regarding the environment in terms of water depth, water oxygenation and terrigenous

clastic input.These types of integration are used to relate lithofacies identification, correlation, stratigraphic sequences, and palaeoenvironmental reconstruction. Knowledge of these geological characteristics can greatly increase the understanding of the equivalent subsurface reservoir, and enhance the reliability of subsurface well log interpretation and correlation.

I hope this can helps you

For any rock identification the more analysis one can do will give clues to the origin of the rock. There are so much data and research done around the world that one can compare with known data for better identification.

Dear Muhammad Hamad

It is difficult to identify and delineate the rock units, minerals, and alteration zones only by using spectral data (i.e., satellite images, FieldSpec Spectroradiometers) without testing and integrating this data with other geological and geochemical data (XRF, XRD, EPMA, ……etc.). Please check the following articles, maybe help you. Also, you will find a lot of articles related to your topic and case studies worldwide in many journals (e.g., Remote sensing, Ore Geology Reviews, EJRS …. etc.).

Earth materials and minerals have their spectral signatures and the spectral signatures of almost all minerals and rocks are in many robust spectral libraries from which remote sensing interpretations make reference; Also the information from geochemistry when integrated further refines any proposed conceptual model about such mineralization.

A good understanding of the associated mineral or mineralization and the geology of the host rock is important in making any meaningful conclusion after such integration.
