Short-term organic cyclicities from the Kimmeridge Clay Formation of Yorkshire (G.B.): combined accity of reduced iron species compared to the massively produced HS. and consequently by the incorporation of HS. in excess within the organic matter. Here, this interpretation is presented as a mathematical model whose results are compared to measured data (for microcycles having organic carbon contedefendant 发表于 2025-3-23 13:56:23

Organic sedimentation and its relationship with palaeoenvironmental changes over the last 30,000 yeatic conditions. Anthropogenic influence is visible from the middle of the Sub-Atlantic. The regional palaeoenvironmental variations are also recorded in other European sites (SchalkenMehrener Maar, Lago di Monticchio), although slight differences occur due to local effects related to the geomorpholCREEK 发表于 2025-3-24 08:21:58

Study of qualitative and quantitative variations in kerogen chemical structure along a microcycle: Pyrolysis products (hydrocarbons, thiophenes, medium polarity compounds, phenols, fatty acids) were identified and their relative abundances determined. These pyrolysis experiments provided information on (i) the chemical features, source organisms and mode of formation of the three types of organic晚来的提名 发表于 2025-3-25 00:34:38
Palaeoproduction control on anoxia and organic matter preservation and accumulation in the Kimmeridbin ., 1991). Short-term organic carbon cycles have been studied in detail by Rock-Eval pyrolysis and biomarker analysis. In agreement with other approaches (this volume), the following scheme for organic matter (OM) preservation and accumulation can be proposed from the results of this study. In ox
