(2006)In October 1993 we carried out a seismic monitoring in the Tres Vírgenes volcanic region in order to record the background seismicity associated with the volcanic structures, the geothermal field and the tectonic features ...
-
(2006)Chondrule D8n in LL3.0 Semarkona is a porphyritic olivine (PO) chondrule, 1300 × 1900 μm in size, with a complicated thermal history. The oldest recognizable portion of D8n is a moderately high-FeO, PO chondrule that is ...
-
(2006)The first palaeontological discoveries in Urumaco were made more than half a century ago. Several research groups have worked in the region, but new vertebrate fossils are still being found in this area of northwestern ...
-
(2006)We conducted seismic cone-penetration tests (SCPT) and tomographic imaging in a permafrost mound in northern Quebec, Canada, to study the cryostratigraphy and assess the seismic properties of permafrost at temperatures ...
-
(2006)Early dinosaur evolution has been the subject of several phylogenetic studies and the position of certain basal forms is currently debated. This is the case for the oldest known members of the group, excavated from the ...
-
E (2006)For most of the past 150 years the presence of only giant megatheriine ground sloths in the Pleistocene of Brazil has been recognised. However, it has recently been claimed that a dwarf Eremotherium species was present ...
-
(2006)A new species of Eurypterus from the Wenlock of Ringerike, Norway is described as E. hankeni sp. nov., based on fine pustular ornament on the carapace and opisthosoma, an enlarged distal podomere of the swimming leg and ...
-
(2006)Two new genera of Mylodontoidea, Mirandabradys and Bolivartherium, and five new species, M. socorrensis (Socorro Formation, Middle Miocene), M. urumaquensis and B. urumaquensis (Urumaco Formation, Upper Miocene), M. zabasi ...
-
(2006)Four new skulls referable to Bairdemys, from the Late Miocene Urumaco Formation in Venezuela, are described and compared with other specimens allocated to this genus. Several characters previously used to distinguish B. ...
-
(2006)An almost complete skeleton of Phoberomys pattersoni is reported from the Urumaco Formation in northwestern Venezuela. Phoberomys attained the largest body size among known rodents and it lived during the Late Miocene ...
-
(2006)Two new genera and species of Megatheriinae are described from the Neogene of Venezuela: Urumaquia robusta gen. et sp. nov. from the Urumaco Formation (Late Miocene) and Proeremotherium eljebe gen. et sp. nov. from the ...
-
(2006)Fossil Crocodylia are taxonomically diverse in South America, particularly in the upper Miocene Urumaco Formation (Venezuela). Among them is the giant alligatoroid Purussaurus, previously known from the upper Miocene ...
-
DESCRIPTION AND SYSTEMATIC RELATIONSHIPS OF †TOMOGNATHUS, AN ENIGMATIC FISH FROM THE ENGLISH CHALK (2006)The Upper Cretaceous fish †Tomognathus mordax Dixon, 1850, is redescribed, based on newly acid-prepared material that reveals many new structures and reinterpretations of some parts of anatomy previously described. The ...
-
(2006)There has been an increasing debate regarding the mechanism controlling the low-frequency polarization (megahertz to kilohertz) in sandstones. The polarization and related electrical relaxation are extremely important ...
-
(2006)In order to provide an indirect method of estimating the hydraulic properties of sandstone aquifer rocks, electrical spectroscopy measurements were made on Permo-Triassic Sandstone over the frequency range 0.0001-1000 Hz. ...
-
(2006)This taxonomic review of the scleractinian corals of the Maastrichtian and Paleocene period focuses on the scleractinian suborders Astrocoeniina, Faviina, Rhipidogyrina and Amphiastraeina. This, the first extensive compilation ...
-
(2006)An appropriate form of induced polarization (IP) acts as a bridge between the structure of a water-saturated core plug and its transport properties. The induced-polarization decay curves of natural rocks can be modeled as ...
-
(2006)We study temporal correlations and multifractal properties of long river discharge records from 41 hydrological stations around the globe. To detect long-term correlations and multifractal behaviour in the presence of ...
-
(2006)Early Triassic and Late to Middle Permian magnetostratigraphic investigations are numerous and span the globe. More than 20 magnetostratigraphic sequences have documented all or part of the Early Triassic geomagnetic field ...
-
(2006)We investigate the respective roles of crustal tectonic shortening and asthenospheric processes on the topography of the High Atlas and surrounding areas (Morocco). The lithospheric structure is modeled with a direct ...
