On the AAPG website, describe the role of Paleontology and Biostratigraphy, and Geochemistry, in petroleum exploration. Explain how each field helps in finding and understanding oil and natural gas resources.
Navigate to 'aapg.org'. From the main navigation, go to the 'About' section, then 'Petroleum Geology'. Within 'Petroleum Geology', navigate to 'Geology and Petroleum'. Access the 'Paleontology and Biostratigraphy' section and extract its role. Return to 'Geology and Petroleum' and access the 'Geochemistry' section, extracting its role. Synthesize the information for both disciplines, explaining their contributions to petroleum exploration.
State that Paleontology and Biostratigraphy study prehistoric life forms (fossils) to determine the age of rock layers, which helps petroleum geologists assess the potential for natural resources. State that Geochemistry studies the chemical composition of Earth and how once-living things decompose to form hydrocarbons (oil). Clearly articulate how both disciplines, by providing insights into rock age and hydrocarbon formation, are crucial for petroleum geologists in assessing resource potential.
