Abstract
The growth strata was investigated in the Early Cretaceous deposits including Fahliyan, Gadvan and Dariyan formations in the Well 3 that is located between Qatar-Fars height and Hormuz Strait in Persian Gulf. This study is based on the lithostratigraphic analysis and microfossils distribution. Lithostratigraphically, the Well 3 is divided into three rock units including Fahliyan, Gadvan and Dariyan. Based on the microfossils content, the age of studied successions is Berriasian to Aptian. The comparison of seismic studies, lithostratigraphic analysis and microfossils distribution show that growth and generation of anticlines construct in the Early Cretaceous. As a result, the Fahliyan, Gadvan and Dariyan rock units have potential reservoir and oil trap.

The Early Cretaceous deposits in the Zagros basin and Persian Gulf have been divided into several rock units including Fahliyan, Gadvan, Dariyan and Kazhdumi formations [1]
The present study has focused on the growth strata in the Early Cretaceous deposits based on the lithostratigraphic characteristics, biostratigraphic analysis and seismic interpretations
Summary
The Early Cretaceous deposits in the Zagros basin and Persian Gulf have been divided into several rock units including Fahliyan, Gadvan, Dariyan and Kazhdumi formations [1]. Investigation of lithostratigraphic characteristics of the Early Cretaceous deposits in the studied well is more effective in order to recognize source and reservoir rocks [5] [6]. The present study has focused on the growth strata in the Early Cretaceous deposits based on the lithostratigraphic characteristics, biostratigraphic analysis and seismic interpretations. The results of this research can assist in detecting and identifying oil traps and their evolution along geological periods [13] [14] For this purpose, the Early Cretaceous deposits have been investigated in one of the well in the Persian Gulf. Persian Gulf is a shallow subduction formed during Neogene period in the southern margin of the Zagros mountains. The studied well is located in the Persian Gulf between the heights of Qatar-Fars and Hormuz Strait (Figure 1)
