An olistostromal
unit, composed of andesite, basalt, sandstone and conglomerate, and limestone blocks
within red-wine colored mudstone matrix is cropped out in surrounding areas of
Balıkkaya hill, Havdan and Sansuvat villages 500 to the west of Biga township
(Çanakkale). The existence and age of this unit is under discussion as it is
accepted in Thanetian-Danian (Paleocene) age based on foraminiferas found in
mudstone and named as Ballıkaya formation. In this area, the limestone blocks
are in Malm-Early Cretaceous age and the matrix to these blocks, however is
rarely exposed and contains red, bordeaux, thin-bedded limestone which is Late Maastrichtian
in age based on foraminferas identified as Globotruncanella
havanensis (Voorwijk),
Globotruncanella citae (Bolli), Abathomphalussp.
