-
(2006)By means of the region-time-length (RTL) algorithm, which is widely used for investigating the precursory seismicity changes in China, Italy, Japan, Russia and Turkey, we examine the precursory seismic activity occurred ...
-
(2006)Both anisotropy and non-linearity of rocks are important properties related to the elastic wave propagation in the Earth. However, in the literature, there has been a continuous increase in the interest of anisotropy, but ...
-
(2006)The trace element compositions of Hadean zircons have been used in two ways to argue for the existence of Hadean continental crust. One argument is based on low crystallization temperatures of Hadean zircons that have been ...
-
(2006)Major and trace element, whole rock Sr and Nd isotope and zircon Hf isotope data are reported for a suite of A-type granites and mafic microgranular enclaves from the Early Cretaceous (126 ± 2 Ma) Qianshan pluton, Liaodong ...
-
(2006)We describe transition metal behaviour during early diagenesis in sediments collected along a transect across the eastern flank of the East Pacific Rise (EPR) at 14°S overlying crust with magnetic ages of 0.36 Ma to 4.6 ...
-
(2006)Citlaltépetl (Pico de Orizaba) is Mexico's highest (5675 m a.s.l.) potentially active volcano, which is presently in a dormant state. Between 9.0 and 8.5 ky B.P., a sequence of volcanic eruptions occurred at Citlaltépetl ...
-
(2006)Mongolia is one of the countries of the Asian continental interior rich in ore and non-metallic deposits. Non-metallic commodities of high-unit and high-place value commodities are found throughout the country. Some reference ...
-
(2006)The Ilugissoq graphite andesite volcano on Nuussuaq belongs to the Asuk Member of the Paleocene Vaigat Formation. It is the largest eruption site within the Vaigat Formation and is recognized as the source of the majority ...
-
(2006)Seismic refraction and reflection data were acquired in 2000 and 2003 to study the morphology and sedimentary fill of the remote El'gygytgyn crater (Chukotka, northeastern Siberia; diameter 18 km). These data allow a first ...
-
(2006)Base surges are a significant volcanic hazard associated with phreatomagmatism, but their transport and depositional dynamics are incompletely understood. Stratigraphic analysis and lateral tracing of surge eruption units ...
-
(2006)Seismic profiling in the equatorial Atlantic reveals deep-water (> 4500 m) sediment bodies formed by current-controlled deposition near the intersection of large-offset fracture zones with the African margin. A 600 km-long ...
-
(2006)SHRIMP zircon U-Pb ages and geochemical and Sr-Nd-Pb isotopic data are presented for the gabbroic intrusive from the southern Taihang Mountains to characterize the nature of the Mesozoic lithospheric mantle beneath the ...
-
(2006)This study uses three acoustic instruments (different in their operating frequencies, 13, 3.5, and 6-10 kHz, and deployment type, hull-mounted, surface-towed and deep-towed) to investigate and characterize the acoustic ...
-
(2006)Long-period magnetotelluric data have used to image the deep electrical structure of the Cascadia subduction zone in British Columbia, Canada. Zones of elevated electrical conductivity were found in both the forearc and ...
-
(2006)Eleven species belonging to five major groups of mammals (multituberculates, eutriconodontans, 'symmetrodontans', metatherians and eutherians) have been described from the Jehol Biota, Liaoning, China. These fossils came ...
-
(2006)Based on high-resolution 3D seismic data sets, we document the subsurface reservoir architecture and organization of a portion of the Oligocene-Miocene stratigraphy within the Congo Basin, offshore southwestern Africa. ...
-
(2006)We present new palaeomagnetic results from Late Cretaceous red beds of the Paomagang Formation collected at 42 sites in the Yichang area (30.7°N, 111.7°E), middle-northern part of the South China Block. A high unblocking ...
-
(2006)Using high quality 3D seismic data within the Lower Congo Basin (LCB), we have identified pockmarks that are aligned above the sinuous belt of a buried turbiditic palaeo-channel, 1000 m beneath the seafloor. Geochemical ...
-
(2006)The effect of shallow marine water (~30-100 m deep) in the late excavation and early modification stages of a marine-target crater 5 km in diameter, as exemplified by the Late Cretaceous Wetumpka impact structure in Alabama, ...
-
(2006)Terrestrial impact structures provide field evidence for cratering processes on planetary bodies that have an atmosphere and volatiles in the target rocks. Here we discuss two examples that may yield implications for Martian ...
