Data supporting nanometer-scale relationships between sedimentary organic matter molecular composition, fluorescence, cathodoluminescence, and reflectance

This data release describes optical photothermal infrared (OPTIR) spectroscopy data used to map sedimentary organic matter functional group distributions at 500 nm resolution in a sample from the Lower Cretaceous Sunniland Limestone from the South Florida Basin. Examined fields of view include occurrences of amorphous organic matter (AOM), inertinite, micrinite, solid bitumen, telalginite, and vitrinite. Data also include traditional organic petrographic data from the same organic grains including fluorescence intensity, reflectance, and scanning electron microscopy as well as against cathodoluminescence response.
