Isotopes in Petroleum Exploration (Pb-Sr) and Verification (14C)

In petroleum exploration, it is vital to be able to interpret and date key occurrences within petroleum systems – including petroleum generation and alteration (post-generation). For example, identifying and dating the occurrence of certain authigenic minerals (e.g. carbonate cements) can provide information on when and where oil is likely to accumulate to aid in targeting exploration.
