“…The field map was refined with satellite imagery from multiple sensors (Table 1). Multiple band ratios from Aster and Landsat imagery were calculated and different combinations were displayed as RGB to aid in the delineation of specific lithologies (Qari et al 2008;Rawashdeh et al 2006;Schetselaar et al 2007; Van der Meer et al 2012). We used high-resolution imagery (GeoEye-1) during subsequent expeditions to improve the field map.…”

The Cocinetas Basin of Colombia provides a valuable window into the geological and paleontological history of northern South America during the Neogene. Two major findings provide new insights into the Neogene history of this Cocinetas Basin: (1) a formal re-description of the Jimol and Castilletes formations, including a revised contact; and (2) chronostratigraphy presented here provides the necessary background information to explore the complete evolutionary and biogeographic significance of the excellent fossil record of the Cocinetas Basin.

“…S1 in the supplementary material available online). The latter procedure is known as pan-sharpening technique and is most widely used for improved geological and environmental information extraction (e.g., Schetselaar, 2001;Al Rawashdeh et al, 2006;Pavlic et al, 2008;Zhang, 2008;Abdallah, 2010;Argyriou, 2012). Using the DEM and its derived slope, we conducted longitudinal profile analyses for five streams or channels, with lengths ranging from 25 to 34 km, which flow on the eastern side of the Wadi Araba rift valley and cross a strong topographic transition between the low-gradient uplands and the deeply incised mountain front on the west side of Jordan (Fig.…”

Detection and analysis of morphotectonic features utilizing satellite remote sensing and GIS: An example in SW Jordan

This study investigates the dominant orientations of morphological features and the relationship between these trends and the spatial orientation of tectonic structures in SW Jordan. Landsat 8 and hill-shaded images, constructed from 30 m-resolution ASTER-GDEM data, were used for automatically extracting and mapping geological lineaments. The ASTER-GDEM was further utilized to automatically identify and extract drainage network. Morphological features were analyzed by means of azimuth frequency and length density distributions. Tectonic controls on the land surface were evaluated using longitudinal profiles of many westerly flowing streams. The profiles were taken directly across the northerly trending faults within a strong topographic transition between the low-gradient uplands and the deeply incised mountain front on the east side of the Dead Sea Fault Zone. Streams of the area are widely divergent, and show numerous anomalies along their profiles when they transect faults and lineaments. Five types of drainage patterns were identified: dendritic, parallel, rectangular, trellis, and modified dendritic/trellis. Interpretation and analysis of the lineaments indicate the presence of four main lineament populations that trend ~E-W, ~N-S, NE-SW, and NW-SE. Azimuthal distribution analysis of both the measured structures and drainage channels shows similar trends, except for very few differences in the prevailing directions. The similarity in orientation of lineaments, drainage system, and subsurface structural trends highlights the degree of control exerted by underlying structure on the surface geomorphological features. Faults and lineaments serve as a preferential conduit for surface running waters. The extracted lineaments were divided into five populations based on the main age of host rocks outcropping in the study area to obtain information about the temporal evolution of the lineament trends through geologic time. A general consistency in lineament trends over the different lithological units was observed, most probably because repeated reactivation of tectonism along preexisting deep structural discontinuities which are apparently crustal weakness zones. The reactivation along such inherited discontinuities under the present-day stress field is the most probable explanation of the complicated pattern and style of present-day landscape features in SW Jordan.

“…Linear contrast stretching for example, produces image showing differences in geomorphological expressions, but poorly defines lineaments. The ratioed image is reliable for distinguishing between the basement rocks and the overlying sedimentary cover in arid regions, as Offield et al (1977) and Rawashdeh et al (2006) mentioned in their study. However, it is still poor in lineament discrimination.…”

A Landsat image of the multispectral scanner system covering an area lying between the Aqabah Gulf and the southern margin of the Dead Sea was analyzed by digital image processing techniques to delineate various geological and structural features of southwest Jordan area. Two major techniques in digital image processing were employed. They are preprocessing and enhancement, and their constituent treatment processes. Types of lithology, lineaments and topographic contrasts of southwest Jordan were used as test criteria. Results of comparison indicate that the combination of images processed by first principal component, second principal component and filtered first principal component as assigned to the hue, saturation and intensity system coordinates, respectively, provided better results than products of other digital techniques. Such good results enable geologists to map major lithologies, lineaments and other structural features effectively, as well as to assess topographic variations.
