Systems geology emphasizes the nature of geology as a system – that is, as a set of interacting parts that function as a whole. [1] [2] [3] The systems approach involves study of the linkages or interfaces between the component objects and processes at all levels of detail in order to gain a more comprehensive understanding of the solid Earth.
A system in stratigraphy is a sequence of strata (rock layers) that were laid down together within the same corresponding geological period. The associated period is a chronological time unit , a part of the geological time scale , while the system is a unit of chronostratigraphy .
Meandering rivers, which form a sinuous path in a usually low-gradient plain toward the end of a fluvial system. Anastomosed river is a rare case of a relatively straight, complicated vertical sequence of river deposits with banks held together by dense vegetation .
