Inter-correlation of Hydrothermal Mineral Alteration Zone in the Vicinity of Lineaments

There are significant and effective roles of geological structures such as lineaments in mineral zone identification and interpretation, exploration and mapping of rock units, litho-boundaries, local tectonic zones and fractures, and hydrothermal alteration facies. The aim of this study was to extract lineaments of Jahajpur region of Bhilwara district, Rajashtan automatically and digitally using Sentinel 2A optical data. The automatic lineament extraction by ‘LINE’ algorithms tool with involvement of several processing steps and parameters of PCI Geomatica evaluated digitally extracted lineaments, geospatial analyses such as length of lineaments, lineament density and lineament orientation. The obtained results were validated through assessment of geomorphic and structural features interpretation by numerical, analogical, and geospatial analysis and field survey for a better understanding and correlation. The vicinity of extracted lineament and lineament densities show the various alteration minerals such as clay, talc, mica, dolomite and goethite. Thus, we can conclude that lineaments have excellent inter-relationship with hydrothermal alteration and weathering zones in the western Jahajpur belt, Rajasthan.
