-
(2006)The Beishan Mountain is located in north-western China and eastern-central part of the Central Asian Orogenic Belt. The granitoid intrusions are well developed and associated with copper, tungsten, gold and molybdenum ...
-
(2006)Rock associations of andesites and diorite in Shaquanzi copper-iron deposits in East Tianshan Mountain in Xinjiang, China, are attributed to cal-alkaline, at close range of alkaline, volcanic rock series. The concentrations ...
-
(2006)Systemic measurements on the concentrations of the radiogenic elements U, Th and K for the 149 core samples obtained from the main drilling hole of the Chinese Continental Scientific Drilling Project (CCSD) have been ...
-
(2006)The latest Permian was a time of major change in ocean chemistry, accompanying the greatest mass extinction of the Phanerozoic. To examine the nature of these changes, samples from two well-studied marine sections that ...
-
(2006)The valley of Chagan Mulun River on the north side of Xila Mulun river in eastern Mongolian, is the east side of southern Da Hinggan Mesozoic volcano-platonic complex zone. Recently, many adakitic volcanic rocks with a ...
-
(2006)The Kalatongke is a large Cu-Ni deposit in the southern part of the Altay orogenic belt, northwestern China. Rhenium and osmium isotopic analyses of Ni-and Cu-bearing sulfide minerals from the deposit have been used to ...
-
(2006)The main hole of the Chinese Continental Scientific Drilling Project (CCSD-MH) is located in the Maobei eclogite complex, south Sulu UHP terrane. Eclogites from 0 ~ 600m in depth of the CCSD-MH are characterized by ...
-
(2006)The ultramafic xenoliths in various quantities and scales were found in the. Quaternary alkali basalts at Abagaqi area of Inner Mongolia These ultramafic xenoliths are composed of spinel Iherzolite, saxonite, dunite, olivine ...
-
(2006)TAG hydrothermal area, located in the Mid-Atlantic Ridge 26.08°N, is one of the largest sea-floor massive sulfide deposits in the sediment-free mid-ocean ridge. New lead and sulfur isotope data are reported in this paper ...
-
(2006)Giant porphyry Cu deposits were formed not only in continental- and island-arcs, but also in continent-continent collisional setting. However, the petrogenesis of ore-bearing porphyry associated with the continent-continent ...
-
(2006)Bernal first suggested the role of clay minerals in the origin of life because of the ordered arrangement of the clay mineral particles, the large adsorption capacity, shielding against ultraviolet radiation, ability to ...
-
(2006)Clay minerals can react with different types of organic compounds in particular ways. Kaolin species (kaolinite, nacrite, and dickite) adsorb particular types of neutral organic compounds between the layers. The penetration ...
-
(2006)The distribution of pyroclasts from 79 A.D. eruption of Vesuvius is analysed to assess the ejection velocities of ballistic particles pertaining to the white and gray eruption phases. This distribution is related to the ...
-
(2006)In order to reconstruct the formation and exhumation mechanisms of UHP metamorphic terrains, the Chinese Continental Scientific Drilling Program (CCSD) has been carried out in Donghai of the Dabie-Sulu ultrahigh-pressure ...
-
(2006)A subjective differentiation can be made between the formation of clay minerals in their natural, geologic environment such as in soils, and the synthesis of pure minerals in a controlled, laboratory environment. The former ...
-
(2006)Except zircons as intergranular grains, zircon inclusions (-10-30 μm) were also found in rutiles as well as garnets in rutile-bearing eclogites recovered from the CCSD main borehole. Backscattered electron (BSE) imaging ...
-
(2006)Magic-Angle-Spinning Nuclear Magnetic Resonance (MAS-NMR) spectroscopy was used to probe the crystallographic environment of Si, Al, F and H in 14 natural talc samples originating from different localities and containing ...
-
(2006)The Tyrrhenian margin of the Apennine chain (TMAC) experienced widespread extensional tectonics characterized by volcanism and the formation of several marine and intermontane troughs and basins in Pleistocene times. The ...
-
(2006)We carried out a systematic study of spinel group minerals in LL3.00-3.9 and LL4-6 chondrites. With increasing petrologic type, the size and abundance of spinel increase. The compositions of spinel group minerals in type ...
-
(2006)Large amount of geological research indicates that there are series Cu-Ni sulphide deposits in south central Jilin Province, eastern portion of the Xing'an-Mongolian Orogenic belt, North China. Hongqiling Cu-Ni sulphide ...
