Abstract The aim of this paper is to calibrate palynofacies with eight classes of phytoclasts using statistical methods in order to construct a reference. Seven categories of palynomorphs are compared to the phytoclast reference. Principal components analysis (PCA) were performed, firstly using separated phytoclast and palynomorph parameters and ...

Maturity estimation of phytoclasts in strew mounts by micro-Raman spectroscopy
International Journal of Coal Geology, 2017Abstract In order to evaluate the potential for petroleum generation of a sedimentary rock, it is important to establish the thermal maturity of its organic matter. In rocks with low total organic carbon, the kerogen has to be isolated by acid maceration, and the traditional maturity assessment via vitrinite reflectance is sometimes hampered by the ...

Abstract Microfossil tubes with internal thickenings, so-called banded tubes, are a conspicuous but enigmatic element of terrestrial palynomorph assemblages of Silurian to Early Devonian age. Their biological affinities and functions are controversial.

Phytoclasts as provenance indicators in the Belgian septaria clay of Boom (Rupelian age)
Sedimentology, 1976ABSTRACTPhytoclasts and coal particles, present in small quantities in a clay sediment, can be used as source rock indicators. The measurement of their reflectivities revealed characteristic low values typical for British Carboniferous coals, outcropping in Northern England, which may be a source area of the sediment.

Special Paper of the Geological Society of America, 1974
Grains of clastic organic matter similar to coal occur scattered among the mineral grains in most shale and sandstone; they are called phytoclasts because many of them have relict plant structures. The phytoclasts that have been least altered in a given sample can be used to determine the degree of metamorphism of the host rock.

Abstract Phytoclast occurrences of coalified and charcoalified wood from British Mesozoic sediments have been investigated by the use of scanning electron microscopy, elemental analysis, electron spin resonance and infra-red spectrophotometry; particular attention has been paid to the properties of charcoalified clasts to allow comparison with ...
