Piramagroon pla<strong>in</strong>, Dokan area it grade<br />

with Shiranish <strong>Formation</strong> and can not be<br />

identified.<br />

4. A type one and two sequence boundary<br />

(SB1 and SB2) is identified; they located<br />

at lower and middle part <strong>of</strong> the formation<br />

respectively. Above each 500m and 30m<br />

<strong>of</strong> conglomerate are deposited<br />

respectively.<br />

5. The (500m) conglomerate has<br />

aggradational stack<strong>in</strong>g pattern, which<br />

deposited <strong>in</strong>side more than four the<br />

<strong>in</strong>cised valleys dur<strong>in</strong>g sea level fall. This<br />

conglomerate changes to thick low stand<br />

wedge <strong>of</strong> sandstone at the distal area.<br />

6. The transgressive surface and<br />

condensed sections are identified.<br />

7. All the system tracts <strong>in</strong> the studied area<br />

are as follow<strong>in</strong>g:<br />

Qamchuqa <strong>Formation</strong>… LST<br />

Kometan <strong>Formation</strong>… TST<br />

Shiranish …. <strong>Formation</strong>…. early HST<br />

<strong>Tanjero</strong> Fn…..late HST, LST, TST and<br />

HST<br />
