Western Turkey has been dominated by N–S extension since the Early Miocene. The timing and cause of this N–S extension and related basin formation have been the subject of much debate, but new data from the Bigadiç borate basin provide insights that may solve this controversy. The basin is located in the Bornova Flysch Zone, which is thought to have formed as a major NEtrending transform zone d...

Sediments deposited during glacial-interglacial cycles through the Early to Mid-Pleistocene in North Sea are chronologically poorly constrained. To contribute chronology of these units, amino acid racemization (AAR) and strontium (Sr) isotope analyses have been performed on samples from four shallow borings one oil well along a transect northern Sea. D/L Asp (aspartic acid) values obtained reve...

A synthesis of the knowledge Schist-Greywacke Domain (SGD) in Portugal is here presented. Until recently, this sequence assumed designation Dúrico-Beirão Supergroup composed by Douro Group (DG) and Beiras (BG). The DG considered Neoproterozoic – Cambrian age BG age. identification mapping an unconformity as Cadomian identified Spain, which splits “lower Alcudian” “upper Alcudian”, a turning poi...
