Milankovitch cycles are quasi-periodic fluctuations in insolation forced by the variation in
Earth's astronomical parameters. The astronomically induced climate change affected the …

The Devonian has long been a problematic period for paleomagnetism. Devonian
paleomagnetic data are generally difficult to interpret and have complex partial or full …

After more than a century of doubt and equivocation, cyclostratigraphy–the stratigraphic
record of astronomically forced paleoclimatic change–has come to be widely accepted in the …

Carbon isotope (δ13C) analyses of marine carbonates spanning the Silurian–Devonian
transition are compared from three richly fossiliferous, well-dated sequences in North …

Based on field outcrop data, the effects of cyclic change of astronomical orbit and volcanic
activity on organic carbon accumulation during the Late Ordovician–Early Silurian in the …

The upper Silurian, and especially Pridoli epoch is a critical interval for the understanding
the evolution of Earth's biota, since it witnessed series of powerful extinction events, global …

The geological record of the Paleozoic often exhibits cyclic features, in many cases the
result of changes in paleoclimate. However, a thorough understanding of the processes that …

Procedures used to define an international chronostratigraphic stage boundary and to locate
and ratify a Global Boundary Stratotype Section and Point (GSSP) are outlined. A majority of …

Spectral reflectance (SR) is a relatively novel technique which is used as a proxy for organic
carbon and siliciclastic input in carbonate sediments, in particular in core research. This …

This paper concerns the analysis of four outcrops in the Frasnian (Upper Devonian) of
Belgium. We compare the results of a precise sedimentological analysis with magnetic …
