The Bronze era is one of the most important cultural periods of pre-history of Iran. The importance of period is more by the period changes and different issues of Bronze era in Iran plateau. So, central Zagros area is one of important cultural area of Iran in Bronze era. In this area archaeological studies and excavations were done; but like other Iran areas, central Zagros has some problems chronologically the problem is seen more in West of central Zagros in Lorestan. In the area, Godin Tepe was chronological base of Bronze era from five decades ago. In this ancient area, excavations set chronology in a way that causes culture vacuity in wide parts of west of central Zagros. The Godin IV period is considered with Early Bronze period that is introduced by Kora – Arax culture. Considering to not seen this area in wide parts of central Zagros, the chronology of these areas have problem. For this, the writers tried to analyze chronological data of Tepe Gariran to solve some of chronological problems in West of central Zagros. in this way, data trenches of W.260, W.275a and W.275b were analyzed and 44 samples of ceramic related to Early Bronze were studied. The studies showed that some kinds of ceramic of phases III:6 and III:5 Godin and also bi-colored ware were popular in Early Bronze. This ancient mound is considered one of largest area in East of central Zagros. The studies in the mound showed the enriched culture of it. The excavation of it showed that there is no cultural vacuity in Tepe Gariran layers and sequence of cultural layers is without interruption. In addition to Godin Tepe, it is used of Western parts of central Zagros and Posht-Koh to set Tepe Gariran chronology. The studies showed that in Early Bronze era, some kinds of painted wares related to Godin III and bi-colored were popular.
