... yield within a high-resolution stratigraphic framework developed for the Alkyonides basin, central Greece. Latest Quaternary highstand deposits are distinguished from lowstand Lake Corinth deposits on the basis of seismic reflection data and micropaleontological and palynological analyses of drop cores...

Figure 2. Sedimentary, palynological, and microfossil data from Alkyonides basin. Graphic logs of gravity cores DC-01 and DC-02 (located in Fig. 3A) include uncalibrated 14C ages (as radiocarbon years B.P.). M—Mytilus sp. bivalves; H—Hydrobia ventrosa gastropods. Pollen percentages of selected taxa and groups and dinoflagellate cyst assemblages are based upon 300 counts per sample. Dots in arboreal vs. nonarboreal pollen percentage graph denote samples with poor pollen recovery. AMS is accelerator mass spectrometer.

Figure 1. A: Location map. B: Late Quaternary base-level history inferred for Gulf of Corinth. Global sea-level curve (after Shackleton, 1987) is modified by local Lake Corinth lowstand. C: Line drawing of analogue, single-channel Sparker seismic reflection line, northern Alkyonides basin. Deltaic clinoform of last glacial Lake Corinth lowstand overlies distal strata of last interglacial marine highstand and is onlapped by deposits of postglacial marine transgression and highstand. Seismic data were acquired with 700J sparker source, Kemo VBF21-M amplifier, and four hydrophone receiver spread.

... and erosional rates. Extrapolation of these rates indicate that some 350 m of footwall relief has been produced over approximately 1 Ma. Most of the sediment eroded from the uplifting footwall is presumed to have been re-sedimented into the Alkyonides Gulf basin plain during this time. The prominent footwall...

... is considered an inactive relict of early rifting, yet the presence of late Quaternary shorelines is evidence of continuing uplift of the north, east and south margins of this basin. Models to explain uplift include uplift on the footwall of the southern Alkyonides Gulf fault system and the Xylocastro–Perachora...

12–0 ka isopach of sediments in the Corinth basin created by merging western gulf Holocene isopach from Beckers et al. (2015) with our central and eastern Holocene isopach. Faults are taken from Nixon et al. (2016). Sediment thicknesses range up to 90 m. Three clear depocenters can be seen along the basin (western Gulf of Corinth, central of Corinth, and Alkyonides Gulf). The isopach has been smoothed using the Petrel smoothing process, with an iteration of 1 and a filter width of 4 (∼200 m). Fault names: PF—Psathopyrgos Fault, TF—Trizonia Fault, AEF—Aigion Fault, WCF—West Channel Fault, AF—Akrata Fault, EEF—East Eliki Fault, DF—Derveni Fault, LYF—Lykoporia Fault, EXF—East Xylokastro Fault, EAF—East Antikyra Fault, LF—Lechaion Fault, E.AIF—East Alkyonides Fault.

(a) The Gulf of Corinth, Greece, on the eastern Mediterranean Aegean–Anatolian microplate. NAF, North Anatolian Fault. (b) Major active fault systems are uplifting the southern margins of the active rift that comprises the Gulf of Corinth and Alkyonides Gulf. Fault locations after Bell et al. (2009). The Lechaion Gulf, not considered part of the active rift, is the study area together with the Perachora peninsula (PP) that separates the active rift from the Lechaion Gulf. The Corinth basin study area is outlined, comprising the Lechaion Gulf and its margins and the Perachora peninsula. (c) The Peloponnese landmass between the rift and the subduction trench overlies the zone where the Aegean–Anatolian plate overrides a shallow-dipping African plate; location of cross-section is shown in (a).

Quantifying timescales to reach uniform relief in emergent ranges. Tier 1 data and data for ranges with independently constrained propagation rates (red symbols in A) are included. (A) Tip zone method: tip zone versus propagation rate, estimated using 10:1 ratio between tip propagation and slip rate (after Densmore et al., 2004). Red circles are ranges with independently measured propagation rates: Kyrgyz Range, S. Alkyonides fault, Kashi anticline, and Wheeler Range (see Notes section in the Supplemental File [see footnote 1]). Curves are contours of the time required for the fault to propagate across the tip zone length. (B) RU method: mean uniform relief (RU) versus rock uplift rate. Curves are contours of the time required for the range to reach uniform relief. Squares—normal faults; circles—reverse faults; filled squares—Basin and Range (B & R); filled circles—Siwalik Hills (SH). (C) Comparison of time needed to reach steady relief between the two methods.
