- Аннотация: We present the new geochemical, paleomagnetic and anisotropy of magnetic susceptibility data from the Kulumbe river area (the Siberian Traps Large Igneous Province). The majority of the studied intrusions have the normal polarity, belong to the Katangsky complex and can be correlated with the upper part of the volcanic section of the Norilsk region. Furthermore, the first intrusive analogues of the Gudchikhinsky Formation are found. The only intrusion showing the reverse magnetic polarity has the geochemical features similar to the ore-bearing Norilsk-type intrusions. Based on the study of the magnetic fabric of the intrusions, we suggest that they were fed from the magma-conducting Imangda-Letninskiy fault.
