Morphometric Analysis to Assess Sea level History and Uplift Rate in the Pleistocene Marine Terraces of Chabahar (Iran)

Friday 19 August 2022 kl. 18:49

Marine terraces are strain markers that can provide crucial information to asses past sea-level changes in tectonically active coastal realms such as in the Chabahar Peninsula, Iran. Here TerraceM was used to accurately measure the elevation of marine terraces to elucidate their pattern of deformation along the strike. The TerraceM analysis allowed us to elucidate the location of active normal faults and their seismic potential.

Variable Quaternary Uplift Along the Southern Margin of the Central Anatolian Plateau Inferred From Modeling Marine Terrace Sequences

Sunday 19 June 2022 kl. 19:02

The southern margin of the Central Anatolian Plateau (CAP) records a strong uplift phase after the early Middle Pleistocene, which has been related to the slab breakoff of the subducting Arabian
plate beneath the Anatolian microplate. We u
sed the TerraceM software to map the position and elevation of associated shoreline angles. Then we used  the TerraceM Landscape Evolution Model that simulates wave erosion of an uplifting coast. Using random optimization algorithms and minimization statistics we find the input parameters that better reproduce the morphology of CAP marine terraces. The best‐fitting uplift rate history suggests a significative increase from 1.9 to 3.5 m/kyr between 500 and 200 kyr, followed by an abrupt decrease to 1.4 m/kyr until the present, which agree with slab break‐off models.

Submerged Marine Terraces Identification and an Approach for Numerical Modeling the Sequence Formation in the Bay of Biscay (Northeastern Iberian Peninsula)

Wednesday 22 April 2020 kl. 17:50

Using bathymetric data and novel mapping and modeling techniques, we studied a submerged sequence of marine terraces in the Bay of Biscay with the objective to identify the distribution and morphologies of submerged marine terraces and the timing and conditions that allowed their formation and preservation.
