-
(2006)Observations indicate that earthquake faults occur in topologically complex, multi-scale networks driven by plate tectonic forces. We present realistic numerical simulations, involving data-mining, pattern recognition, ...
-
(2006)The gold metallogeny of Turkey constitutes a sector of the Tethyan Eurasian Metallogenic Belt (TEMB) within the Alpine-Himalayan orogenic system that formed from Jurassic-Cretaceous to the present. This orogenic system ...
-
(2006)Study of Devonian tetrapods and their relatives spanning the so-called 'fish-tetrapod' transition has expanded almost exponentially in the last 15 years or so. This evolutionary event is now represented by at least nine ...
-
(2006)Granulite xenoliths from the Cretaceous-Paleogene Tuoyun basalts in the southwestern Tianshan area (NW China) are mainly pyroxene granulite and olivine granulite, with minor garnet granulite and quartz granulite. They can ...
-
(2006)Marine microbial communities recorded in the Moroccan Anti-Atlas were unaffected across the Neoproterozoic-Cambrian transition. A stromatolitedominated consortium was replaced at the beginning of the Atdabanian (ca 20 Myr ...
-
(2006)Wide-angle reflection-refraction profiles at crustal scale have been obtained along a 700 km transect of northeastern Tibet from six shotpoints. A combination of sampling by broadside fan-recordings and in-line profiling ...
-
(2006)The three-dimensional (3D) lithospheric density structure of the Eastern Alps was investigated by integrating results from reflection seismics, receiver function analyses and tomography. The modelling was carried out with ...
-
(2006)Indium-bearing deposits at Mount Pleasant, New Brunswick represent one of two major episodes of mineralization associated with granitic intrusions near the southwest margin of the Late Devonian Mount Pleasant caldera. ...
-
(2006)A large number of studies of water in pyroxenes have confirmed that essentially all pyroxenes of terrestrial origin as a rule contain substantial amounts of OH, varying as a function of chemical composition and geological ...
-
(2006)The micro-satellite DEMETER was launched on June 29, 2004 in a polar and circular orbit with an altitude of ~710 km. It is a CNES mission controlled from Toulouse in France. The main objective of DEMETER is to search and ...
-
(2006)The Fortuna oxidized gold skarn deposit is located in the northern part of the Nambija gold district, southern Ecuador. It has been subdivided into four mineralized sites, covering a distance of 1 km, which are named from ...
-
(2006)Stable and radiogenic isotope composition of stratiform Cu–Co–Zn mineralization and associated sedimentary rocks within the Boléo district of the Miocene Santa Rosalía basin, Baja California Sur, constrains the evolution ...
-
(2006)The country rock in southern Finland formed mainly during the Svecofennian orogeny ca. 1.9 Ga ago. The middle and lower crust was partially melted 1.83 Ga ago due to crustal thickening and subsequent extension. During this ...
-
(2006)The reliance on aquifers which are shared by more than one country is increasing. Yet, shared aquifers are only rarely addressed in international treaties, despite the wide recognition of the desirability of comprehensive ...
-
(2006)The water level fluctuations and geomorphology of Lake Nasser reservoir in Tushka area, Egypt, has its own bearing on the local hydrogeological regime. Comparison of the available data concerning the submerged bottom ...
-
(2006)Radon levels were surveyed in 517 monitoring wells constructed in five major groundwater areas of Taiwan. The radon concentration in groundwater samples varied in a wide range from below the detection limit of 18 pCi/L up ...
-
(2006)Major and trace element as well as Sr–Nd isotopic compositions of mid-Cretaceous lavas across western Shandong Province, China have been studied. These lavas can be generally divided into southern Shandong group (including ...
-
MODELING STREAM-AQUIFER INTERACTIONS IN A SHALLOW AQUIFER, CHOELE CHOEL ISLAND, PATAGONIA, ARGENTINA (2006)A groundwater/surface-water interaction model was developed for the shallow alluvial aquifer of the Choele Choel Island in Patagonia, Argentina. In this semiarid climate, agriculture is sustained by an irrigation/drainage ...
-
(2006)Ground penetrating radar (GPR) has proved to be an extremely useful geophysical tool, in conjunction with direct geological data, to develop a realistic, macroscopic, subjective-based conceptual model of aquifer architecture ...
-
(2006)One of the most important processes leading to the deterioration of groundwater in Israel is the migration of brines penetrating into fresh groundwater bodies. Such manifestations occur at an ever increasing frequency and ...
