Paleomagnetic dating of rocks of the Bolshesyrsky magmatic area of the Minusinsky basin
Paleomagnetic dating of the Bolshesyrsky igneous area, a thick intraplate igneous complex of Khakassia, was carried out. The complex has not been dated due to the peculiarities of the stratigraphy and the lack of suitable rocks for applying the methods of absolute geochronology. The use of the paleo...

| description | Paleomagnetic dating of the Bolshesyrsky igneous area, a thick intraplate igneous complex of Khakassia, was carried out. The complex has not been dated due to the peculiarities of the stratigraphy and the lack of suitable rocks for applying the methods of absolute geochronology. The use of the paleomagnetic method has shown that the paleomagnetic pole of the red beds, which are intruded by sills and dikes of the Bolshesyrsky area, is close to the Silurian paleomagnetic poles of Siberia and Tuva and differs sharply from the Ordovician paleomagnetic poles of these areas. That is, red-colored rocks are Silurian, and subvolcanic rocks are post-Silurian. The sharp unconformable overlapping of the red-colored and volcanic strata with the Middle Devonian sedimentary trough without igneous rocks indicates that the age of the Bolshesyrsky complex is limited to the Silurian-Early Devonian interval. The genesis of the rocks of the Bolshesyrsky magmatic area was associated with the activity of the Early Devonian Minusinsk plume. |
