maceral中文是什么意思

Maceral maturity can be estimated by " vitrinite reflectance ".
In rare cases, maceral and fossilised pollen can be found in terrestrial sedimentary rocks.
The term'maceral'in reference to coal is analogous to the use of the term'mineral'in reference to igneous or liptinite.
A high cleat density is required for profitable exploitation of CBM . Also important is the maceral composition : maceral is a microscopic, homogeneous, petrographic entity of a corresponding sedimentary rock.

Himmetolu oil shale seam consists of more than 50 % liptinite, 20 50 % huminite and 0 20 % inertinite maceral groups and is characterized by its high organic content.
The vitrinite reflectance value represents the highest temperature that the vitrinite maceral ( and source rock ) has experienced, and is routinely used in 1D burial modelling to identify geological unconformities in sedimentary sections.
The lack of vitrinite macerals in marine shales with little terrestrial input often requires alternative maturity parameters instead of vitrinite reflectance such as Rock-Eval Tmax, biomarker equivalences and other maceral reflectance parameters ( e . g . liptinite reflectance ).
