Stepwise combustion analyses of distinct nitrogen isotopic compositions on Paleoproterozoic organic matter
Carbonate-rich sandstones (samples 0708 and 0704) were collected from outcrop of the Gunflint Formation, Ontario, Canada (sample 0708: 48°29 ′24.4′′ N, 89°11′34.2′′ W; sample 0704: 48°29′24.6′′ N, 89°11′35.3′′ W). Samples contain 0.34 and 0.23wt% organic carbon. The estimated age for the Gunflint Formation is ca. 1.9 Ga (Fralick et al., 2002), and its metamorphic grade is considered to be sub-g...
متن کاملNew Data on Carbon Isotopic Compositions of Some Ureilites
Introduction: The ureilites are an unusual class of carbon-rich, ultramafic, achondritic meteorites, which display both primitive and evolved characteristics. For example, their noble gases (which are carried largely in the diamond phase) display a planetary or fractionated signature, and their O isotopes retain a heterogeneity imparted from the solar nebula [1,2]. Paradoxically, though, the mi...
متن کاملSources and diagenetic status of organic matter in the Hauraki Gulf, New Zealand: Evidence from the carbon isotopic composition of D- and L-amino acids
The origin of sedimentary organic matter and the influence of microbial reworking in the Hauraki Gulf, New Zealand, were determined using the stable carbon isotopic compositions of sedimentary Dand L-amino acids. Core top sediments from three offshore and five inner Gulf sites were collected using a multi-corer. After correction for microbial alteration of original source materials, source appo...
متن کاملThe Sources of Carbon and Nitrogen in Mountain Lakes and the Role of Human Activity in Their Modification Determined by Tracking Stable Isotope Composition
We studied the isotopic composition of organic matter in the sediments of eight mountain lakes located in the Tatra Mountains (Western Carpathians, Poland). The sediments of the lakes were fine and course detritus gyttja, mud, and sand. The total organic carbon content varied from 0.5 to 53 %. The C/N ratio indicated that in-lake primary production is the major source of the organic matter in t...
متن کاملMolecular Isotopic Characterization of the Alh 85013.50 Meteorite: Defining the Extraterrestrial Organic Compounds
Introduction: The Antarctic Meteorite Program has returned over 16,000 meteorites from the ice sheets of the Antarctic. This more than doubles the number of preexisting meteorite collection and adds important and rare specimens to the assemblage. The CM carbonaceous chondrites are of particular interest because of their high organic component. The Antarctic carbonaceous chondrites provide a lar...
