Tectonic Evolution of Arabian Plate - five development stages
• During S - C1,plate position did not change much but rotated 100o clockwise.
• Two periods of glaciation due to high latitude

2007年石油贸易状况图
2007年中东石油出口量达到了9.75×108t,占世界石油出口总量 27.01×108t的36.11%,我国从中东进口石油高达7880×104t。

Key Points
1. Tectonic evolution of Arabian Plate 2. Depositional history of Persian Gulf Basin 3. Salient features of petroleum geology of the basin 4. Why the basin is so rich in oil and gas
Middle Cambrian
Late Cambrian
A shallow marine carbonate developed in north during Middle Cambrian but later replaced by continental to shallow marine clastics
I. Precambrian basement
II. Late Precambrian to Late Devonian intracratonic stage This stage can be divided into 3 phases Late Pre-cambrian rifting (II1) Early Cambrian-Late Ordovican sagging (II2) Late Ordovician-Late Devonian post-glacial sagging (II3)
