Shallow Thermal Anomalies and their Role in the Breakup Evolution along the Conjugate Margins of the Fram Strait (Svalbard and eastern North Greenland), Indicated by Low-temperature Thermochronology

Here we present thermochronology data from sedimentary rock samples of late Cretaceous to Paleogene age with unusually high thermal maturities from eastern North Greenland and western Svalbard. The data are interpreted and discussed in the article "Shallow Thermal Anomalies and their Role in the Breakup Evolution along the Conjugate Margins of the Fram Strait (Svalbard and eastern North Greenland), Indicated by Low-temperature Thermochronology", submitted to the journal Geochemistry, Geophysics, Geosystems. The data include apatite (U-Th-Sm)/He analyses (table S2) and apatite fission track analyses (dataset S1). We used the thermochronology data to derive time-temperature histories. In the document "Supporting Information", we provide the analytical protocols (Text S1-3, S5), data visualization and assessment for influences and relationships (Figures S2, S3, S4), modelling strategy, parameters and results (Text S4, Figure S5, Table S3), and thin section analyses of the host rock and associated quartz veins (Figures S6-9, Table S4-5). It also contains a summary of the analysed samples, their sampling locations and the resulting AFT and AHe ages (Table S1).
