Event V from Tevekkelli Trench
At the Tevekkelli Trench, excavated across the
southwestern part of the
Pazarcık segment of the East Anatolian Fault,
Yönlü and Karabacak (2023:5-6) identified
Event V as an older surface rupture in Tevekkelli
T1, predating the beginning of unit h and following deposition of
unit f. The trench exposed a prominent
shear zone
made of pervasively sheared
plastic clay gouge,
with
shear fabrics
and faulted blocks indicating dominant
strike-slip movement.
A
radiocarbon sample
from unit h, which postdates Event V, produced a
calibrated age
of 3321–2871 BCE (
2σ), while a sample from unit f,
which predates Event V, produced a calibrated age
of 5961–5631 BCE (2σ). These two samples therefore
constrain Event V to between 5961 and
2871 BCE (2σ) but also after Event U in the Tevekkelli Trench.
Yönlü and Karabacak (2023:6) note that more
events could be expected between Event V and
Event X, but that evidence for these intervening
events could not be identified, probably because
later surface ruptures overwrote earlier fault
strands within the same narrow fault zone.
