Mediterranean sapropels are layers with elevated organic carbon concentrations that
contrast with surrounding sediments, which are organic poor. Sapropels occur (quasi-) …

Sapropel formation in the eastern Mediterranean coincided closely with minima in the
precession index. Such minima occur approximately every 21000 years. At such times …

The prevailing explanation for the origin of organic-rich sediments and rocks invokes
deposition under conditions of anoxia. However, recent research suggests that high primary …

The oxygen and carbon stable isotope compositions of cave speleothems provide a
powerful method for understanding continental climate change. Here, we examine the …

An astronomically calibrated timescale has recently been established [Hilgen, 1991a, b] for
the Pliocene and earliest Pleistocene based on the correlation of dominantly precession …

In the subsurface of the East Mediterranean Sea, eleven discrete basin-wide, organic-rich,
black sapropels were deposited during the last 465 000 years. They are dated by oxygen …

Abstract The Croll–Milankovitch astronomical theory of climate1–3 has received strong
support from the evidence of a linear climatic forcing by obliquity and precession, although …

Abstract In an East Mediterranean marine core, the upper sapropel begins soon after the
start of a global event—a very heavy precipitation which occurred in the equatorial latitudes …

Abstract The late Pliocene-early Pleistocene sapropel-bearing sequences exposed in the
Vrica, Semaforo, Singa and Punta Piccola sections of southern Italy and the Francocastello …

We present an integrated geochronology for late Neogene time (Pliocene, Pleistocene, and
Holocene Epochs) based on an analysis of data from stable isotopes, magnetostratigraphy …
