Abstract
The structure of the junction between the Turukhan zone of deformation and the Kureika Basin was studied using regional reflection profiling data acquired along the Lower Tunguska River, with reference to well logs and land-based geological surveys. The western flank of the line comprises four large blocks separated by faults, which produce different patterns in seismic sections. The eastern part of the line covers the margin of the Kureika Basin filled with plane-bedded sediments and its border with the Turukhan Uplift and the Turukhan tectonic zone with thrust sheets.
