STRATIGRAPHY AND SEDIMENTOLOGY<br />

Fig.2.8: Four limestone successions at the <strong>lower</strong> part of Qulqula Formation, west of<br />

Dostadara Village, N latitude 35 o 34 - 47.33 = and E longitude 45 o 46 - 45.63 = (P1, P2, P3<br />

and P4 are limestone successions).<br />

Members<br />

One of the difficulties that stand against this study is indicating whether these<br />

limestone successions are overturned or not. As the studied area is located in the<br />

Thrust Zone, the overturning is not excluded, due to imbrication and subsequent<br />

<strong>possible</strong> thrusting. To achieve these data, the field study w<strong>as</strong> conducted to indicate<br />

the top and bottom of the successions by using sedimentary structures. Most<br />

outcrops are almost devoid sedimentary structures. The useful structures are:<br />
