Provenance (geology)
Provenance in geology, is the reconstruction of the history of sediments movements over time. The Earth is not a static but a dynamic planet, all rocks are subject to transition between the three main rock types, which are sedimentary, metamorphic, and igneous rocks (the rock cycle). Rocks exposed to the surface, sooner or later, are broken down into sediments. Sediments are expected to be able to provide evidence of the erosion history of their parent source rocks. The purpose of provenance study is to restore the tectonic, paleo-geographic and paleo-climatic history.
