New data on the age of magmatic events in Oloy tectonic zone, West Chukotka area (evidences from zircon U-Pb dating)
Keyword(s):
Zircons from volcanic and plutonic rocks of Nembonda volcanic field (the part of Anadyr segment of the Okhotsk-Chukotka volcanic belt) yield the following SHRIMP U-Pb ages, Ma: 147,72; 123,81,7; 119,31,7; 9,80,5; 80,550,96. These results confirm the hypothesis about the significant Aptian magmatic event in Verkhoyansk-Chukotka tectonic province, and give rise to the revision of the boundaries of the Okhotsk-Chukotka belt.
