Paleogene-Neogene Fauna and Flora
of Eastern Sakhalin Island
     


 This study, authored by Vostokgeologia, is based on data from a large number of surface exposures and onshore wells along the east-central Sakhalin coast. The study consists of two volumes, both of which are included in all purchases.

Volume 1 contains the text of the report (slightly over 200 pages), along with a large number of charts, graphs and tables.  It also includes photographs and descriptions of approximately 60 thin sections, as well as detailed charts of the distribution and abundance of fauna and flora for the individual sites within the study area. 

Volume 2 is composed of over 850 photographs of the fauna and flora used in the work presented in Volume 1, including:

  • Marine mollusks (Sections I-XV)

  • Diatoms (Sections XVI-XXXVIII)

  • Palinoflora (Sections XXXIX-IV) 

  • Lithologic columns for key sections - Lunsk trough

The study is currently available from Wavetech at a price of US$ 6,500.  For more information, please contact Mr. Jack Holton at Wavetech.
