Abstract
This study aimed at identifying and mapping hydrothermally altered minerals in parts of Delhi fold belt near Jaipur city, India, using EO-1 Hyperion data. The rock type found in this area is Quartzite of Ajabgarh Series of Delhi Super group. Space based Hyperion hyperspectral data results have been analyzed and compared with different laboratory analysis techniques like X-ray diffraction and spectroradiometer on the selected rock samples. Though, the SNR of the Hyperion image was low (18:1) but different hydrothermally altered and clay minerals like muscovite, kaolinite, kaolinitesmectite and montmorillonite have been identified. The data was in good confirmation with the laboratory and spectroscopic analysis. Surface mineralogy of this area was mapped with the help of Hyperion image and was found in good confirmation with the field observations. On the basis of the mineralogy of the area, it can be concluded that this zone is mainly subjected to the intermediate argillic alteration. During the field survey a fault has also been identified in the study area.
