“…The connections with the Filiates structure are not visible at the surface, because the whole area is covered by very recent sediments (the Kalamas River delta plain; Chabrol et al. (2012)). We believe that the BSW is connected to the Filiates structure through a narrow area, where the evaporites are squeezed, forming a weld zone that is also cut by a SW‐directed thrust (near Smertos) (Figure 10).…”

The Ionian Zone (IZ) is one of the key elements of the fold and thrust belt (FTB) of the Albanian and Hellenides orogen and contains large outcrops of Triassic evaporites. The IZ consists of various thrust sheets with a general westward vergence, stacking over the Apulian and Pre‐Apulian zones, and repeating a thick carbonate sequence of Upper Triassic to Eocene age. Thrusting becomes younger toward the west with a piggyback sequence, starting during the latest Oligocene Epoch in the Internal Ionian and ending in the Pliocene in the External Ionian. We have studied the IZ in southern Albania and northwestern Greece using field observations and borehole data and by fully interpreting a recently acquired 2D seismic data set. Our objectives are to establish the geometry and nature of the contacts associated with the major Triassic outcrops, to unravel precursor salt diapirs, and to assess their role during the Alpine contraction. Salt structures include gentle salt pillows, isolated salt plugs and diapirs, thrust welds, and salt walls. Combining these observations with experimental modeling results, we show how these structures control the geometry and kinematics of the Alpine thrusts or the location and kinematics of recent strike‐slip faults. Salt minibasins have also been identified, demonstrating salt mobility conditioned Mesozoic sedimentation in the Ionian Basin. The use of salt‐tectonics principles to evaluate the structural style and evolution of the IZ FTB also opens new directions for interpreting the subsurface structure and evolution of the region.

“…In addition, according to observations around Sayiadha, we propose the wall is resolved toward the SE by a subvertical weld that is partially cut by a thrust sheet to the SW (Figure 10). The connections with the Filiates structure are not visible at the surface, because the whole area is covered by very recent sediments (the Kalamas River delta plain; (Chabrol et al, 2012)). We believe that the BSW is connected to the Filiates structure through a narrow area, where the evaporites are squeezed, forming a weld zone that is also cut by a SWdirected thrust (near Smertos) (Figure 10).…”

“…Over the last 40 years, the geoarcheology of the Greek shoreline has produced a large literature dealing with both the Aegean (Genre, 1989;Ghilardi, Kunesch, Styllas, & Fouache, 2008;Ghilardi et al, , 2010Ghilardi et al, , 2013Goiran, Pavlopoulos, Fouache, Triantaphyllou, & Etienne, 2011;Kraft, Aschenbrenner, & Rapp, 1977;Kraft & Rapp, 1975;Pavlopoulos et al, 2006;Syrides, Vouvalidis, Tsourlos, & Matas, 2009;Triantaphyllou et al, 2010;Vouvalidis et al, 2010) and Ionian coasts (Chabrol, Fouache, Le Coeur, Apostolopoulos, & Pavlopoulos, 2012;Fouache et al, 2005;Kraft, Rapp, & Aschenbrenner, 1998;Vött, 2007).

This article examines the shoreline evolution and human occupation in the vicinity of the important archeological site of Amarynthos (Euboea Island, Greece) over the last six millennia. Archeological evidence indicates a continuous occupation of the site from the Bronze Age to the Roman period and the site is well-known, thanks to the existence of a sanctuary dedicated to the goddess Artemis. Based on the study of four boreholes, a paleogeographic reconstruction of the coastal landscape is proposed. Facies were determined based on mollusc identification, and sedimentology based on grain-size measurements (hand sieving for the fraction above 2 mm and LASER technique for particles below 2 mm) and loss-on-ignition. In addition, a series of 12 AMS radiocarbon dates define a reliable chronostratigraphy. Results suggest the presence of a fully marine environment from the early Holocene to ca. 2600-2400 cal. BC, which developed into a brackish environment from ca. 2600-2400 cal. BC to ca. 750 cal. BC due to the deltaic progradation of the nearby stream (Sarandapotamos River). From ca. 750 cal. BC onward, coastal swamps prevailed in the study area. Human-environmental interaction is discussed and particular attention is paid to the paleolandscape configuration of Amarynthos.
