Provenance (geology)
http://dbpedia.org/resource/Provenance_(geology) an entity of type: Museum
En géologie, la provenance (en français dans la littérature anglophone), est une sous-discipline du source to sink qui vise à déterminer l'origine de sédiments. Cette origine peut être géographique, en déterminant la région dont l'érosion a produit le sédiment, ou lithologique, en déduisant le type de roche dont est issu le sédiment.

Provenance in geology, is the reconstruction of the origin of sediments. 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 erosional history of their parent source rocks. The purpose of provenance study is to restore the tectonic, paleo-geographic and paleo-climatic history.

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 to determine the origin of sediments. This is often used in conjunction with the study of exhumation histories, interpretation of drainage networks and their evolution, and forward-modelling of paleo-earth systems. In combination, these help to characterise the "source to sink" journey of clastic sediments from hinterland to sedimentary basin.
