Abstract
    The Azmir-Goizha anticline elongates directly to north and northeast boundary of Sulaimani city, Kurdistan Region, NE-Iraq. The anticline is originally consisted of two main connected anticlines (Goizha and Azmir anticlines) at southwest and northwest of the studied area respectively with many other smaller ones. The anticline has the length, width and elevation of about 10, 4 and 1.6 kms (amsl) respectively. It elongates from Weladar village, from southeast to Khamza village at the northwest. The anticline is relatively complex and during the last decade, many structural, paleontological and stratigraphical studies were conducted on it but without utilizing them for accurate solving complexity. The present study tries to use the field study and nannofossils aging for simplifying and showing actual geologic setting of the anticline. The previous occurrence of 63m of Dokan Formation and its unconformable lower boundary are refused. On the basis of clear stratigraphic horizon, the geological map of the anticline is completely changed and new stratigraphic units are shown. The map shows that the anticline is mainly covered by Balambo Formation instead of previous Kometan Formation. Moreover, the Sarmord Formation is identified for the first time in the area and differentiated from Balambo Formation. Sarmord Formation crops out and occupies the core of the anticline which can be seen from Khamza to Weladar villages at the northwest and southeast of the studied area respectively. For the first time, the equivalents of Gulneri and Dokan formations are shown and discussed in the area.
