Provenance (geology) diagenetic changes that occur in siliciclastic sediment during burial and uplift". Provenance studies are conducted to investigate many scientific questions, for example, the growth history of continental crust, collision time of Indian and Asian plates, Asian monsoon intensity, and Himalayan exhumation Meanwhile, the provenance methods are widely used in the oil and gas industry. "Relations between provenance and basin are important for hydrocarbon exploration because sand frameworks of contrasting detrital compositions respond differently to diagenesis, and thus display different trends of porosity reduction with depth of burial." All rock exposed at the Earth's surface is subjected to physical or chemical
Provenance to prove ownership. An example of a detailed provenance is given in the Arnolfini portrait. The quality of provenance of an important work of art can make a considerable difference to its selling price in the market; this is affected by the degree of certainty of the provenance, the status of past owners as collectors, and in many cases by the strength of evidence that an object has not been illegally excavated or exported from another country. The provenance of a work of art may vary greatly in length, depending on context or the amount that is known, from a
