Notarchirico is at a nodal point in time and space for understanding the settlement of Europe terms migration or situ evolution. Former technological analyses have not shown significant differences between different lithic assemblages Notarchirico. Our approach here to produce phylogenetic analysis taken as terminal interpreted cultural units. In cladistic framework, characters are hypotheses r...
Abstract One of the primary purposes seismic stratigraphy is to evaluate components layer relationships within a depositional chronology. Prestack images contain wealth information, such as variations in offset and azimuth event, naturally produce higher-resolution facies analysis results than poststack data. However, prestack data usually suffer from potential unreliability issues due low sign...
logic map of Northeast Gale crater. Solid and patterned shapes represent unique geologic units identified through morphological classifications using HiRISE and CTX. Blue and green outlines indicate identification of mafic and hydrated mineral phases found through the use of CRISM. STRATIGRAPHY OF THE GALE CRATER RIM AND FLOOR UNITS. J. Buz 1 and B. L. Ehlmann 1,2 , 1 Geological & Planetary Sci...
APPROACH In July-August 1998 aboard the USNS Bowditch, we collected sediment cores, CTDs and XBTs, 3.5 kHz subbottom profiles, and high-resolution 48-channel seismic profiles. This survey covered as much of the Gulf as possible given the restrictions that reefs, oil fields and territorial limits have on ship operations. The approach was to seismically map Neogene stratigraphy and tie this struc...
NPLD reflectors and no evidence for basal unit. 2.5 μs is approximately 420 m in water ice. ABALOS MENSA, PLANUM BOREUM, MARS: A CONSTRUCTIONAL, AEOLIAN HISTORY DERIVED FROM RADAR AND OPTICAL STRATIGRAPHY, REINFORCED BY ATMOSPHERIC MODELING. T. C. Brothers, J. W. Holt, A. Spiga, University of Texas Institute for Geophysics, Jackson School of Geosciences, University of Texas, Austin, TX 78758 tc...
The Karoo basin of South Africa exposes a succession of Upper Permian to Lower Triassic terrestrial strata containing abundant terrestrial vertebrate fossils. Paleomagnetic/magnetostratigraphic and carbon-isotope data allow sections to be correlated across the basin. With this stratigraphy, the vertebrate fossil data show a gradual extinction in the Upper Permian punctuated by an enhanced extin...
