The Yammouneh Fault at its type area of Yammouneh village. The fields
lie in a broad polje - a karstic depression - formed betwen two strands
of the fault. It looks like a pull-apart basin - but is probably a relay
ramp. Here we look north. The northern strand of the fault lies at the
foot of the snowy ridge (Mount Lebanon) and runs off into the distance.
The southern fault strand lies on this side of the polje and dies out
northwards.
It all looks very active tectonically but landscape processes here are
slow. Run-off of water is almost non-existant - it flows in cave systems.
So these tectonic landforms could be very ancient. Trenching is needed
in the sediments.
