Principal components analysis for borate mapping

Identification of hydrothermal alteration minerals for exploring of porphyry copper deposit using ASTER data, SE Iran

“…PCA is a well-known Hubner, 1969b;Mars and Rowan, 2006). method for lithological and alteration mapping in metalogenic provinces (Crosta et al, 2003;Ranjbar et al, 2004;Kargi, 2007;Massironi et al, 2008;Moore et al, 2008;Tangestani et al, 2008;Amer et al, 2010). Standard PCA transformation has applied to the two full ASTER scenes of the Sarcheshmeh and Meiduk regions.…”

Iron ore prospection East Aswan, Egypt, using remote sensing techniques

“…(2) Principal Component Analyses (PCAs) to produce uncorrelated output bands, segregate the noise components and to reduce the dimensionality of data sets in the way of showing iron ore concentrations, (3) band ratio methods have been used for exploring the iron ore rich localities separating them from the host rocks and creating an iron index map, (Crosta and Filho, 2003;Kargi, 2007;Massironi et al, 2008;Moore et al, 2008;Tangestani et al, 2008;Amer and Kusky, 2010;Pour and Hashim, 2011, 2012a,b, 2013Hashim et al, 2011). Several band ratios of ETM + and Landsat 8 have been experimented for finding the efficient ones in iron exploration.…”

Space-Borne Imagery and Geochemical Characters of Post-Orogenic Dyke Swarms, Fatirah-Abu Zawal District, Eastern Desert of Egypt

“…Also, several studies around the world have used the PCA and band rationing techniques of TM data for mapping hydrothermal alteration zones and lithologies (e.g. [27] [61]).…”
