Soil organic matter (SOM) characterization by Rock-Eval pyrolysis: scope and limitations

Can Rock - Eval pyrolysis assess the biogeochemical composition of 1 organic matter during peatification ?

Understanding the responses of soil organic carbon to an increase in global temperature is crucial to estimate potential feedbacks on global warming. In such a context, Rock-Eval pyrolysis has been recently proposed as a screening tool to investigate soil organic matter (SOM) chemistry and vulnerability. In order to test the validity of Rock-Eval as an indicator of SOM chemistry and of OM trans...

Geochemical Characterization of Kazhdumi Source Rock in the Khaviz Oil Field, Southwest of Iran, Using Rock-Eval Pyrolysis

The Khaviz oil field located in Dezful embayment is one of Iran’s southwest oil fields. In this study, a total of 28 cutting samples from Kazhdumi formation (well No. KZ1, Khaviz oil field) were subject to geochemical investigation using Rock-Eval pyrolysis for the first time. The results of pyrolysis indicated that Kazhdumi source rock has significant hydrocarbon production potentiality and al...

Characterization of Organic Matter in Soil and Aquifer Solids

The focus of this work was the evaluation of analytical methods to determine and characterize fractions of subsurface organic matter. Major fractions of total organic carbon (TOC) include: particulate organic carbon (POC) in aquifer material, dissolved organic carbon (DOC) and both volatile (VOC) and non-volatile (NVOC) organic carbon sub-fractions. POC makes up the bulk of TOC in contaminated ...

Pyrolysis-Gas Chromatography to Evaluate the Organic Matter Quality of Different Degraded Soil Ecosystems

Dynamics and fate of natural and waste organic material in soils: the role of the soil organic matter (SOM) recalcitrance in SOM turnover

Previous studies suggested that micropore surface area (MiS) of bio-macromolecules of biomass constitutes an important factor that explains their preservation in soil, that is, the preservation against biological degradation. On the other hand it has been reported that biochemical catalysis are limited in theirs action by the very complex macroscopic and microscopic structure of cell walls that...
