Structural and textural specific features of rocks of Trap Rock Association in the Norilsk Trough (NW of Siberian platform)

This paper presents a detailed analysis of the structure of the Trap Rock Association in the Norilsk Trough and presents data from the petrographic examination of the volcanics. We recorded new data that allow us to renew and supplement the available information on the trap association. We used the drill core from a drill hole 1100 m deep (the hole penetrated 1039 m of volcanics) as a study target. We were able to reveal the thicknesses of the formations, their flows, the petrographic composition of volcanics, and their structural and textural specific features. We examined rock variability up the section in analogous rocks belonging to different rock associations.
