enhancement of jahani (firouzabad) salt dome lithological units, using principal components analysis

in this study, principal components analysis was used to investigate lithological characteristics of jahani salt dome, firouzabad. the spectral curves of rocks in the study area show that the evaporate rocks have the highest reflectance at specified wavelengths. the highest reflection has been seen in gypsum and white salt, while minimal reflection can be observed in the igneous rocks from the region. the results show that pcs have significantly low information. it is clear that pc1 shows more information in the highest variance while pc2 has less information. regional geological map and field controls show compatibility between the enhanced zones and outcrops in the field.
