Abstract:
The middle Cambrian-early Ordovician transgression in the Alborz Mountains resulted in the deposition of members 1 through 3 of the Mila Formation showing an overall transgressive trend. This succession is bounded unconformably by the Top-Quartzite of the Lalun Formation at the below and member 4 of the Mila Formation at the top. It consists of tidal flat to open marine facies, which have been deposited in an extensive ramp on the Proto-Paleotethys passive margin of northern Gondwana. It is composed of six depositional sequences aged middle to early- late Cambrian, related to Sauke 2 supersequence. These sequences are correlated with those recognized in other parts of the world including Oman, China, and North America suggesting that they were formed as the consequence of global relative sea level fluctuation.
