Two general tectonic aspects of the Simpson Group have been revealed by means of lithofacies and paleogeologic analysis of formations comprising the group: (1) a basin and stable shelf with pronounced structural elements, which appear to be intrinsically related to the Precambrian complex...

..., homotaxy does not prove it. Relative age is established by superposition in single sections. Forms present in any population represent the influence of the time, but also of habitat reflected in lithology (lithofacies) and of paleogeographic factors controlling migration. Comparisons are commonly made...

... In this analysis an attempt is made to subdivide Devonian sedimentational history into divisions or episodes in order that the succession of events may be more easily visualized and critically studied. These episodes resulted from a continuously evolving sedimentary process as determined by waxing and waning...

... in the present fold belt of Iran. The paleogeologic patterns of the fold-belt area are likely to be pre-Carboniferous. Variegated strata in pre-Permian lithofacies indicate episodes of regression. However, the common occurrence of a normal invertebrate fauna indicates that marine transgression was important...
