USGS Gulf Coast Source Rock Database (ver. 2.0, October 2023)

The USGS Gulf Coast Source Rock Database (GCSRD) is an online repository for all publicly available source rock data (outcrop and subsurface) from the states of Florida, Georgia, Alabama, Mississippi, Louisiana, Arkansas, and Texas. "Source rock data" are defined in this context as data that include any of the following measured or calculated parameters: -total organic carbon (TOC), -various pyrolysis measurements (Tmax, S1, S2, S3, HI, OI), -vitrinite or bitumen reflectance values. All data in the GCSRD have been extracted from previously published peer-reviewed literature or as USGS-released data sets; no new measurements are included. The underlying data set is presented as an interactive, map-view application where the user can filter by state, original publication, data type, age, or formation, which can be displayed and exported as needed. This release updates the initial (2021) GCSRD by adding 697 new entries to the initial data set.
