Some new "strokes to the portrait" of magmatism of the zimneberezhnykimberlite area of the Arkhangelsk diamond-bearing province(XXI century, first quarter)

In the 80s ‒ 90s of the 20th century, it was established that the manifestations of the late Devonian magmatism of the Zimneberezhny district, diverse in composition, form a regular system, which includes two complete series of kimberlite rocks (alumina and iron-titanium) and basalts. New magmatic bodies discovered in the 21st century added important "strokes" to the already known features of the petrological type, age, geological structure and material composition of magmatic bodies.
