The Earth is a dynamic planet, and all rocks are subject to transition between the three main rock types: sedimentary, metamorphic, and igneous rocks (the rock cycle). Rocks exposed to the surface are sooner or later 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. In the modern geological lexicon, "sediment provenance" specifically refers to the application of compositional analyses
Provenance such by scientific examination. He established an impressive (but false) provenance and because of this galleries and dealers accepted the paintings as genuine. He created this false provenance by forging letters and other documents, including false entries in earlier exhibition catalogues. Sometimes provenance can be as simple as a photograph of the item with its original owner.
