Add a definition Maceral maturity can be estimated by "vitrinitereflectance". From Wikipedia ![]() Vitriniteforms diagenetically by the thermal alteration of lignin and cellulose in plant cell walls. From Wikipedia ![]() Vitrinitemacerals when observed under the microscope show a boxlike, cellular structure, often with oblong voids and cavities which are likely the remains of plant stems. From Wikipedia ![]() They are also used in materials science and biological research and for determining the energy content of coal and petroleum source rock by measuring thevitrinitereflectance. From Wikipedia ![]() Fluid-inclusions technique for determining maximum temperature in calcite and its comparison to thevitrinitereflectance geothermometer. From theCambridge English Corpus Note thatvitrinitereflectance data tend to yield overestimates of denudation, whereas remnant subsidence data tend to yield underestimates. From theCambridge English Corpus Vitrinitereflectance, which typically demonstrates an exponential evolution of organic matter as a function of time, is the best organic indicator for thermal maturation. From Wikipedia ![]() The highvitrinitecontent of the coal indicates a significant potential for coalbed methane production. From Wikipedia ![]() The optical properties of semifusinite are very similar to those ofvitrinite. From Wikipedia ![]() Thevitrinitegroup, which consists of various individualvitrinite"macerals", is the most common component of coals. From Wikipedia ![]() The reflectance ofvitrinitewas first studied by coal explorationists attempting to diagnose the thermal maturity, or "rank", of coal beds. From Wikipedia ![]() The thermal history of a basin is usually calibrated using thermal indicator data, includingvitrinitereflectance and fission tracks in the minerals apatite and zircon. From Wikipedia ![]() Regardless,vitriniteis not soluble in water and could therefore only contaminate fire features in the stratum as particulate matter. From Wikipedia ![]() They differ in that semifusinite displays a folded texture as compared tovitrinitewhich generally maintains its composed structure. From Wikipedia ![]() Conversely, carbonates, evaporites and well-sorted sandstones have very lowvitrinitecontents. From Wikipedia ![]() Vitrinitehas a shiny appearance resembling glass (vitreous). From Wikipedia ![]() In minor scale it also consists ofvitrinite, inertinite, telalginite, and bitumen. From Wikipedia ![]() Inertinites also displays higher reflectance thanvitrinite, except when approaching an anthracitic or graphite state. From Wikipedia ![]() These examples are from corpora and from sources on the web.
