New data on brown coal occurrences in the Yamutarida and Dyuntaturku-yamu river basin in the northern part of the Yenisei-khatanga trough
Background. New information was obtained on brown coal occurrences in the northern part of the Yenisei-Khatanga trough (Lake Taimyr area). This region continues to attract the attention of geologists and oil producers due to its established oil and gas potential.Aim. To study the lithological featur...
