TLDR
A revised age calibration of the Messinian salinity crisis onset in the Mediterranean at 5.971 Ma based on the recognition of an extra gypsum cycle in the transitional interval of the Perales section (Sorbas basin, Spain) and the revision of the magnetostratigraphy of the Monticino section (Vena del Gesso basin, Italy) was proposed in this paper.Abstract:
We propose a revised age calibration of the Messinian salinity crisis onset in the Mediterranean at 5.971 Ma based on the recognition of an extra gypsum cycle in the transitional interval of the Perales section (Sorbas basin, Spain) and the revision of the magnetostratigraphy of the Monticino section (Vena del Gesso basin, Italy). This age re-calibration allows to state more accurately that: (i) the interval encompassing the MSC-onset is continuous, thus ruling out any erosional feature or stratigraphic hiatus related to a major sea-level fall affecting the Mediterranean; (ii) the first gypsum was deposited during the summer insolation peak at 5.969 Ma associated with an eccentricity minimum and roughly coincident with glacial stage TG32; (iii) the MSC-onset was preconditioned by the tectonically-driven reduction of the hydrological exchanges with the Atlantic Ocean and finally triggered by glacial conditions in the northern hemisphere and by arid conditions in northern Africa.read more

Mineral Resources in Egypt (II): Non-metallic Ore Deposits
TL;DR: The authors reviewed four types of non-metallic ore deposits in Egypt: phosphate, white sand (glass sand or silica sand), argillic and evaporite deposits, and found that white sand is one of the most important types.

TL;DR: In this article, the authors present an updated time frame for the 30m thick late Miocene sedimentary Trachilos section from the island of Crete that contains the potentially oldest hominin footprints.

Time‐probabilistic approach to the late Miocene Messinian salinity crisis: Implications for a disconnected Paratethys

TL;DR: In this paper , a time-probabilistic approach was developed to evaluate the distribution of precession-related deposits in the Mediterranean and concluded that Lago Mare accumula tions were not in a Mediterranean-wide lake filled with Paratethyan waters.

A long-term numerical solution for the insolation quantities of the Earth
Jacques Laskar,Philippe Robutel,F. Joutel,Mickael Gastineau,Alexandre C. M. Correia,Alexandre C. M. Correia,Benjamin Levrard +6 more
TL;DR: In this article, a new solution for the astronomical computation of the insolation quantities on Earth spanning from −250 m to 250 m was presented, where the most regular components of the orbital solution could still be used over a much longer time span, which is why they provided here the solution over 250 m.

Chronology, causes and progression of the Messinian salinity crisis
TL;DR: The authors presented an astronomically calibrated chronology for the Mediterranean Messinian age based on an integrated high-resolution stratigraphy and tuning of sedimentary cycle patterns to variations in the Earth's orbital parameters.

Alternate interpretation of the Messinian salinity crisis: Controversy resolved?
TL;DR: A high-resolution chronology of the Mediterranean Messinian salinity crisis is proposed in this article, where two types of evaporite deposition may be distinguished: those in marginal areas vs. those in basinal ones.

TL;DR: In this article, seismic reflection profiles in the western part of the Gulf of Lions were used to confirm the basinward extension of the Messinian erosion and enable the mapping of distinctive seismic markers indicating Messinian Erosional Surface (or Messinian unconformity), the basin margin detrital deposits, and the deep evaporite sequence.
