longer than recognized for any zoned hotspot track in the Pacific thus far. The southeastern Gough subtrack is chemically more enriched and may reflect the composition of the African superplume, whereas the more depleted northwestern Tristan subtrack could be derived through mixing of the ambient depleted mantle with the enriched material. Finally it appears that seismic anomalies are not simply thermal but also chemical in nature and that chemical zonation of hotspots could map out chemical heterogeneities in the lower mantle.


Refining the Mediterranean "Messinian gap" with high-precision U-Pb zircon geochronology, central and northern Italy
Domenico Cosentino et al., Dipartimento di Scienze Geologiche, Universit degli Studi Roma Tre, 00154 Rome, Italy; and Istituto di Geologia Ambientale e Geoingegneria-CNR, 00138 Rome, Italy. Posted online 25 Jan. 2013; http://dx.doi.org/10.1130/G33820.1.

At the end of Miocene (5.96-5.33 million years ago) the progressive closure of the Atlantic-Mediterranean connection induced a major evaporative event known as the Messinian Salinity Crisis (MSC), which lead to the near complete desiccation of the Mediterranean Sea and the deposition of thick evaporite layers. Astronomical tuning of the precessionally modulated sedimentary cycles deposited during the MSC has indicated and approx. 90-thousand-year "Messinian gap," corresponding to the evaporative drawdown of the Mediterranean following complete closure of the Mediterranean-Atlantic gateway.


Evidence for large-scale methane venting due to rapid drawdown of sea level during the Messinian Salinity Crisis
