Özet:

 


It is hoped that important evidences about the formation and evolution of Eastern Pontid's can be obtained
from a geological study of Pulur massif. Therefore, a total of 430 km area belonging to Pulur massif between Bayburt and Demirözü
has been studied.The oldest basement of the area is the Pulur metamorphic complexes. At the base a metamorphic schists,
which has a 600 m apparent thickness and at the top 200 m thick limestones of Permo-Carboniferous age are placed. Lower
Jurassic formations, which consist of basal conglomerates and sandstones, disconformably overlie the Pulur massif. This formations,
are conformably overlain by volcano-sedimentary series of Liassic age. During the Liassic time intensive volcanism yielded
the dasite, andesite, diabase and basalt masses. Some basalts contain larce analcime phenocrysts that the rock can be named analcimite.
Liassic volcano-sedimentary formations are conformably overlain by 50-60 m thick limestones of Dogger age. This limestones
are also conformably overlain by another limestone facies of Malm-Lower Cretaceous age. At the top a melange facies of
Aptien-Albien age are seen. These indicate that the Pulur area was a marine depositional environment at least since Carboniferous
or since Devonian until Upper Cretaceous, except a time gap between Permian and Lias. This marine basin was shallow at the
beginning but .gradually became deeper starring from Dogger time. In the region, two different type metamorphism, which are
homblende-hornfels facies of contact metamorphism and Barrowian type amphibolite facies of dynamo-thermal metamorphism,
are distinguished. The structural character of the region is similar to Alpine type tectonic. Anticlines, synclines, faults and large
extention of a thrust faults, which are elongated in NNE—SWW direction, are the most important features of that tectonic style.
