| Research Abstract |
Allowing only minimal plant growth, the Arctic today is looked under snow-and-ice climate. However, the fossil forests of Axel Heiberg Island found in 1986 by J.F. Basinger, the Canadian representative of present project, and of Ellesmere Island by ourselves in the 1991 preliminary survey tell us that the Arctic was warm and moist as to support lush forest growth in Mesozoic and Tertiary. The fossil forests are literally forests in which live forests were burried and preserved in situ and allow us to reconstruct not only such original stand structure as species composition, special distribution of trees and competition among them etc., but also the general climate and environment of the time.
In the 1992 fieldwork, the excavation and reconstruction were carried out at the "Fossil Forest Hill Site" east of Geodetic Hills, Axel Heiberg island, and the "Museum Site" and "New Site" both on Strathcona fiord, Ellesmere Island. In each of the three sites, a score of forest-bearing beddings are exposed in a geological sequence of burial and deposition.The Fossil Forest Hill Site was characterized by undipped layers of bedding and fossil stumps, logs and leaf litters only mummified but not yet silicified, whereas bedding was dipped and tree remains were silicified at the both sites on Ellesmere Island.
