『Abstract
Distribution and genesis of amber-type resins are discussed.
The kerogen evolution diagram (atomic ratios of three key elements:
carbon, hydrogen, and oxygen) has been used for comparing different-age
fossil resins and refining their genesis and the results of postdiagenetic
effects on them. Paleozoic and Meso-Cenozoic fossil resins occupy
different areas in the mentioned diagram, suggesting a higher
transformation degree of resins from the Paleozoic sediments and
different types of resin-producing vegetation in the Paleozoic
and Meso-Cenozoic. Distribution of data points on the plot can
provide insight into postdiagenetic processes (magmatism, weathering)
responsible for the transformation of some fossil resins. Epochs
of intense succinosis and large-scale amber appearance are attributed
to global events that impaired stable conditions for the growth
of resin-generating forest vegetation.』
