The dataset of various geological and geophysical data is presented for the eastern part of the Russian Arctic zone, a hard-accessible territory with complex geological structure, poorly studied by direct geophysical methods. These data can be used in a combined qualitiaive and quantititive analysis of the lithospheric structure of this territory.

The dataset includes the gravity field and its several reductions appropriate for study of the Earth interiors, heat flow model and 4 tomographic models covering the whole Arctic Region, analyzed to select the best one for further investigations.
Also new models for the sedimentary cover and for the Moho depth, significantly improved compared to the existing ones, are included in the dataset.

This dataset was prepared as a part of the research fundedby the Russian Science Foundation
(project No. 21-77-30010).

• Main reductions of the gravity field and the sedimentary basin structure in the eastern part of the Russian Arctic zone.
• Depth to the Moho in the eastern part of the Russian Arctic zone.
• A new geothermal heat flow model for the Arctic region based on inversion of seismic and magnetic data.
• Seismic tomography models of the Arctic region.
