These silisiclastic sedimentary strata were deposited in a coastal to shallow shelf environment. Based on four outcrop sections and four electric well logs, the depositional facies of these strata deepen from east to west significantly. In the studied area, the sequential variations of these deposits indicate that there were six transgression-regression cycles of relative sea-level during the deposition of the Mushan Formation. It is suggested that basin morphology and sediment supply influenced the lower sequences; whereas Eustacy dominated the upper ones. |
