Sedimentary Record Of Mid-Miocene Seismotectonic Activity In The Sinop Peninsula, North-Central Turkey, Ayhan Ilgar
Sedimentary Record Of Mid-Miocene Seismotectonic Activity In The Sinop Peninsula, North-Central Turkey, Ayhan Ilgar
Turkish Journal of Earth Sciences
The middle Miocene shallow-marine siliciclastic succession in the Sinop Peninsula, north-central Turkey, bears a well-preserved sedimentary record of syndepositional deformation associated with the buried escarpment of an oblique-slip dextral reverse fault and attributed to seismotectonic activity. The deposition occurred in a marginal trough at the edge of a tectonically inverted retroarc foreland basin of the Central Pontides. The synsedimentary deformation involved contemporaneous shoreface deposits and their consolidated, weakly cemented littoral substrate. Deformation features include neptunian dykes, convolute stratification, plumose transposition structure, injection dykes, diapirs, and large sandstone blocks dislodged from the fault escarpment. The genetic sequence of deformation structures deciphered …

Investigation Of Fault-Related Small-Scale Fluid Flow In Geothermal Fields By Numerical Modeling, Doğa Doğan
Turkish Journal of Earth Sciences
In this paper, hydrothermal circulations and temperature distributions in geothermal areas with fault zones are investigated. It is shown that existence of the fault zones influences both the fluid circulation patterns and velocities. Reciprocal influence of the local fluid circulations and the temperature distribution is demonstrated. A 2-dimensional square porous layer is used for modeling the geothermal field. Faults are modeled as vertical porous layers. It is assumed that faults are located inside the geothermal field and have a higher permeability than the field itself. Anisotropic and isotropic models are used to simulate the permeability structure of the faults. Several …
