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
Means to an end something leading into something else, thus it is an end in itself. Means to an end In philosophy, the term "means to an end" refers to any action (the means) carried out for the sole purpose of achieving something else (an end).
