近日,中国地质大学地质过程与矿产资源国家重点实验室赵来时教授团队在国际著名期刊《Geochimica et Cosmochimica Acta》发表题为Raman spectral, elemental, crystallinity, and oxygen-isotope variations in conodont apatite during diagenesis(牙形石磷灰石的拉曼光谱、元素...
We present carbon- and oxygen-isotope compositions in a shell (δ13CS and δ18OS, respectively) of a modern brachiopod Campagea japonica collected at a water depth of 606 m off Aguni-jima, Central Ryuk...
Theoretical and experimental aspects of oxygen isotope fractionation in carbonate minerals are critically examined based on a direct comparison of fractionation factors for carbonate-water systems. T...
Austre Okstindbreen, the largest glacier of the Okstindan area, Norway, covers about 14 km2 within a drainage basin of 22.5 km2. Each year, about one third of the discharge of the glacier river resu...
Oxygen isotope variations of the Wolf and Red Rivers, Wisconsin are very small (1 to 5 ‰ variation) compared to those of local meteoric precipitation (25 ‰ variation), with behavior that may be modele...
In this study we explore the use of natural CO2 emissions in Yellowstone National Park (YNP) in Wyoming, USA to study responses of natural vegetation to elevated CO2 levels. Radiocarbon (14C) analysis...
Stratospheric and upper tropospheric air samples were collected during 1994–2004 over Sanriku, Japan and in 1997 over Kiruna, Sweden. Using these archived air samples, we determined the triple oxygen-...
We report the first measurements of coupled nitrogen (N) and oxygen (O) isotope fractionation of nitrate by laboratory cultures of denitrifying bacteria. Two seawater strains (Pseudomonas stutzeri, Oc...
专著信息 书名 The oxygen isotope effect in the ab-plane reflectance of underdoped YBa2Cu3O7 语种 英文 撰写或编译 作者 N. L. Wang,T. Timusk,J. P. Franck,P. Schweiss,M. Braden,A. Erb 第一作者单位 出版社 Phys. Rev. Lett. 89, 0870...
期刊信息 篇名 Heinrich event imprints in the Okinawa Trough: evidence from oxygen isotope and planktonic foraminifera 语种 英文 撰写或编译 撰写 作者 Tiegang Li,Zhenxia Liu,Michael A. et al 第一作者单位 Iitute of Oceanology, C...
期刊信息 篇名 Hydrogen and oxygen Isotope Study on the Water-Rock Interaction of the Yinshan(Cu)Pb-Zn-Ag ore Deposit,Jiangxi province 语种 英文 撰写或编译 作者 Zang Ligang 第一作者单位 刊物名称 ACTA GEOLOGICASINICA 页面 1996,Vol....
The sensitivity of El Niño-Southern Oscillation (ENSO) to changes in mean climate is investigated for simulations of pre-industrial and mid-Holocene (6000 years before present) climate using th...
We report the first measurements of coupled nitrogen (N) and oxygen (O) isotopic variations of nitrate (NO )2 3 during its assimilation by laboratory cultures of marine phytoplankton and deriv...
Abstract: Oxygen-isotope data were obtained for synthetic aluminum-hydroxide phases precipitated over 65–125 mo and have been compared to results from similar experiments conducted for 3–56 mo. The Al...
Abstract: Oxygen isotopic compositions were determined for coexisting mixed-layer serpentine-chlorite (Sp-Ch) and illite-smectite (I-S) from 5 Tuscaloosa Formation sandstone cores sampled between 1937...
