Decline in extinction rates and scale invariance in the fossil record

open access: yes, 1998
We show that the decline in the extinction rate during the Phanerozoic can be accurately parameterized by a logarithmic fit to the cumulative total extinction. This implies that extinction intensity is falling off approximately as the reciprocal of time.

Thermotectonic evolution of an extensional dome: the Cenozoic Osogovo-Lisets core complex (Kraishte zone, western Bulgaria) [PDF]

open access: yes, 2018
The Kraishte region of Bulgaria is located at the junction of the Balkanides and Hellenides-Dinarides tectonic belts. Fission-track analysis on both apatites and zircons documents the Cenozoic exhumation of a Precambrian basement bounded by low-angle ...

Subcidence patterns (rate of evolution) of Moscow basin

open access: yesRUDN Journal of Engineering Research, 2013
Moscow basin had subsided in two “half-waves” velocity regime over the time-span: Cambrian (Vendian) — Devonian and carboniferous. Subsidence pattern of this basin in devonian-carboniferous was similar to that of the Dnepr-Donezk rift basin.
