COMMISSION II: Geological Applications of Coal and Organic Petrology

Most of the activities of this commission deal with the petrological techniques used to study dispersed organic matter (DOM) in sedimentary rocks. Working Groups have covered a range of activities such as the selection of indices to measure past temperatures in rock sequences, the identification and classification of dispersed organic matter and the improvement of vitrinite reflectance measurement of DOM. In addition, subjects as coalbed methane generation, CO₂sequestration in coal seams or environmental applications of organic petrology are allocated in Commission II.

Accreditation Programme

Convenor: Prof. João Graciano Mendonça (graciano@geologia.ufrj.br)

Dispersed Organic Matter Vitrinite Reflectance Accreditation Programme (DOMVR) for random vitrinite reflectance analysis. In this program, the ability of an analyst to identify and measure the vitrinite reflectance of a rock sample according to ISO standards is tested.
