The first 40Ar/39Ar age data for trap intrusions of the western part of the Siberian Platform.

The article focuses on the development of trap intrusions in the sedimentary cover of the Siberian Platform. It states that the most complete data for the wide development of trap intrusions was obtained as a result of oil and gas prospecting in the Siberian Platform. It says that three samples were collected from the holes of Kt-1, Gf-4 and SV-1 and the data were obtained using the 40Ar/39Ar method. It reveals that new data for the intrusive traps of the Siberian Platform shows evidence of the occurrence of trap magmatism in the different blocks of the sedimentary cover.
