In a new paper we shed light on the tectonic evolution of the Dinarides. Along the Dinaric coast, we mapped a system of uplifted marine terraces in the field and from remote sensing data. These terraces are found at up to 600 m elevation above sea level. Another indication of the uplift of the Dinarides are deeply incised river channels on both sides of the Adriatic-Black Sea watershed. We were able to constrain the timing of the uplift to 28-17 Ma. The combination of our observations with geophysical data suggests that delamination of the lithospheric mantle and subsequent isostatic readjustment caused the uplift. Our study not only shows how this deep process affects surface deformation. It also proves that the traces of such events are preserved over millions of years and that the external Dinarides did not experience significant deformation after the uplift.
