Mapping sedimentary and volcanic units within and surrounding Petrified Forest National Park, Arizona, using Landsat-5 and SPOT panchromatic data

Abstract

Landsat Thematic Mapper (TM ) and SPOT panchromatic data were analysed to determine the lateral variation of the sedimentary and volcanic formations within and surrounding the Petri ed Forest National Park in northeastern Arizona. Detailed geological mapping of portions of Petri ed Forest National Park allowed for a correlation between TM images and the geological formations that aided in identifying these formations in unmapped areas outside and inside the park. A variety of image processing techniques, including band ratios, RGB composite images, selective principal component analysis and Brovey transformations were used in distinguishing these geological formations. Newly determined regions of the Lower and Upper parts of the Petri ed Forest Member of the Chinle Formation were identi ed south of Pilot Rock and east of the Blue Mesa region. A nal spectral re ectance-based geological map created by a maximum likelihood supervised classi cation algorithm provides a rst-order approximation to the location of numerous sedimentary and volcanic units within and surrounding Petri ed Forest National Park.

Landsat-TM-Based Discrimination of Lithological Units Associated with the Purtuniq Ophiolite, Quebec, Canada

“…TM data have been applied with some success in the mapping of prominent zones of mineral alteration such as those marked by the presence of abundant oxides and hydroxides (e.g., [23,24]). In general, because the potential for discrimination of lithologies is greatest in the near-and mid-infrared ranges of the spectrum, TM bands 3 (0.63-0.69 μm), 4 (0.76-0.90 μm), 5 (1.55-1.75 μm), and 7 (2.080-2.35 μm) have proven to be especially useful in past geological work (e.g., [17,25,26]). …”

Application of remote sensing and GIS in mineral resource mapping-An overview

“…Fraser et al, 1997;Mickus and Johnson, 2001;Chatterjee et al, 2003). Wiart et al (2000) mapped the extent of pumice deposits from a previous (1861) eruption of the Dubbi volcano, located in the northeastern part of the Afar triangle, Eritrea, using JERS 1 SAR and Landsat TM imagery.…”

Analysis of an Active Fault Geometry Using Satellite Sensor and DEM Data: Gaziköy-Saros Segment (NAFZ), Turkey

“…These studies have been taken advantage of the higher spectral resolution of Landsat TM data compared with other satellite sensor images (e.g. SPOT HRV data) to obtain a better discrimination between many lithological and structural features [30]. In addition to this, combining Landsat TM data with a higher spatial resolution data, such as SPOT HRV Panchromatic data provide a better discrimination of lithological and morphological features with the advantages of increasing spatial resolution (Figure 2(a)).…”
