Addition to the article by V.A. Vinogradov “Basite and granite age and structural relationships in the intrusion of the Tulai­Kiryak Rise, Southeast Taimyr”

The paper by V.A. Vinogradov’s paper is added by the recent history of the Tulai­-Kiryak intrusion study, results of U­-Pb dating (SHRIMP) while compiling state geological maps­1000/3. Problems of the intrusive granitoids origin are discussed and a conclusion is drawn on the possibility of their formation as a result of anatexis of Permian terrigenous strata that explains the age datings of zircons and high graphite content in them.
Keywords: Tulai-­Kiryak Rise intrusion, shrisgeimite, granite, zircons, anatexis, graphite.
