Phanerozoic tectonic and sedimentation history of the Arctic: constraints from deep-time low-temperature thermochronology data of Ellesmere Island and Northwest Greenland
We present thermochronology and geochronology data from basement and (meta-)sedimentary samples collected on Ellesmere Island (Canadian High Arctic) and Northwest Greenland.

Summary: | We present thermochronology and geochronology data from basement and (meta-)sedimentary samples collected on Ellesmere Island (Canadian High Arctic) and Northwest Greenland. The interpretations of our data are described and discussed in a paper in the journal Tectonics, titled “Phanerozoic tectonic and sedimentation history of the Arctic: constraints from deep-time low-temperature thermochronology data of Ellesmere Island and Northwest Greenland”. Our data include apatite fission track analyses, apatite (U-Th-Sm)/He analyses, and U-Pb analyses of detrital zircons. The data were used for inverse Monte Carlo simulations for obtaining time-temperature histories. We include descriptions of the analytical details related to the measurements, tests for potential effects of radiation damage on the (U-Th-Sm)/He age distributions, and we display the results of the Monte Carlo simulations for the individual samples. Our data set comprises a table summarizing constraints and specific parameters used for simulations (Table S1, summary input modelling), a table displaying the results of the simulations (Table S2, summary outcome thermal history inversions), a table displaying calculations of modelled overburden (Table S3, calculation of net burial and exhumation), a table summarizing the results of apatite fission track data, followed by several tables with the single-grain age and length data of fission track analyses (Table S4), a table with the detailed results of apatite (U-Th-Sm)/He thermochronology (Table S5), a table with single-grain zircon U-Pb data (Table S6), and a table with the results of statistical analysis for distinguishing individual age groups from the detrital zircon U-Pb age distributions (Table S7). |
