Geological Application of Graptolite Reflectance
| July 29, 2023 | Filled under Com II |
|
Introduction The working group on Geological Application of Graptolite Reflectance was established in the 2022 ICCP New Delhi conference. Graptolite reflectance (GR) is the most significant thermal index for establishing thermal maturation in pre-Devonian rocks, and is needed to integrate this work into the efforts of the ICCP. Objectives At the ICCP Meeting in […] more
Pseudovitrinite Working Group
| February 27, 2020 | Filled under Com II |
|
Background The Pseudovitrinite Working Group is concerned with investigating the precise nature and properties of the material referred to as pseudovitrinite, and with the need for its recognition in rank studies and coal utilization. The term pseudovitrinite was introduced by Benedict, Thompson, Shigo & Aikman (1968) to describe vitrinite-like material in Appalachian coals which displays […] more
Confocal Laser Scanning Microscopy (CLSM)
| October 22, 2017 | Filled under Com II |
|
Objectives The objective of the Confocal Laser Scanning Microscopy working group (CLSM WG) was to investigate applications of confocal laser scanning microscopy in organic petrology. The working group was established within the ICCP Commission II in 2015 at the ICCP Meeting in Potsdam and finalized during the 2021 ICCP Meeting in Prague. The WG was […] more
DOMVR and Component Identification Results on microscopy samples in Commission II of the ICCP
| April 5, 2015 | Filled under Com II |
|
Objectives To make widely available the results of the WGs over the years dealing with different aspects of identification, classification and analysis of dispersed organic matter Introduction The WG was born as consequence of the review performed by Werner Hiltmann on the results of the Isolation of Organic matter WG over the years and presented at […] more
Dispersed organic matter in sedimentary rocks
| April 5, 2015 | Filled under Com II |
|
Objectives The objective of the Dispersed Organic Matter in Sedimentary Rocks WG is to provide a reference text for the petrographic analysis of dispersed organic matter including identification of components and thermal maturity. The Working Group has been established in 1995 with the objective to provide an Atlas of Dispersed Organic Matter (DOM Atlas). Since […] more
Identification of Dispersed Organic Matter
| April 5, 2015 | Filled under Com II |
|
Objectives The Identification of Dispersed Organic matter working group (IDOM WG) was created in Budapest (2004) upon revision of the activities of the former Isolation of Sedimentary Organic Matter WG (1988-1998). The focus of this WG is to test the applicability of the existing nomenclature of dispersed organic matter classified in accordance to the ICCP-TSOP Classification […] more
Classification of Dispersed Organic Matter ICCP-TSOP DOM Atlas
| April 5, 2015 | Filled under Com II |
|
This project is a joint effort of the International Committee for Coal and Organic Petrology (ICCP) and of The Society for Organic Petrology (TSOP). The Classification system was agreed to in 2003 and is a single system for different illumination modes. An Atlas is under preparation which illustrates the appearance of the different dispersed organic components […] more
Qualifying Vitrinite for DOM Reflectance Analysis
| April 5, 2015 | Filled under Com II |
|
Objectives The group was created in 1999 (Bucharest) to test and discuss a qualifying system for vitrinite particles in order to determine the quality of reflectance data. Milestones The labelling system initially proposed by J. Koch (BGR, Hannover) was discussed, tested and modified to improve the definitions. At the meeting in Utrecht (2003) it was […] more
Identification of Thermal Maturity Relevant Organic Matter
| April 5, 2015 | Filled under Com II |
|
AIM The Identification of Primary Vitrinite WG (now Identification of Thermal Maturity Relevant Organic Matter WG) was created at the Oviedo meeting in 2008 with the aim of providing guidelines for identification and reflectance measurement of the thermal maturity relevant population in dispersed organic matter. Previous results from Commission II regarding the qualification of vitrinite […] more
Concentration of Organic Matter
| April 5, 2015 | Filled under Com II |
|
Aim The effect of the isolation procedure on organic matter optical properties has been a past objective of ICCP round robin exercises. A review by Angeles Borrego of exercise results demonstrated that some questions remain open. Therefore a reactivation of the concentration working group activities was decided at the 2007 ICCP Meeting in Victoria. Objectives The main objective of the […] more
