Höchster Berg ist der Tchasnachorr mit fast 1200 m. Im Osten liegen die Täler der Flüsse Tuljok, Vuonnemiok und Maivaitajok. Eine vielfältige Vegetation reicht von einer lichten Fichten-Birken-Taiga über Wald- und Strauchtundra bis hin zur Flechtentundra und zu steinigem Ödland.

Peter Seroka has addressed the issue in several years of work and has written an up-to-date geological summary. He dedicated his work to the 15 th anniversary of Mineralienatlas. The work gives detailed information regarding the origin of deposits, the different types of deposits and their classification. Examples of economically important deposits complete the chapters. Provided that this comprehensive work would be printed it would be a volume of over 400 pages; here it is provided in its entirety, online. Thanks to Peter Seroka. (written in german language). |
