Abstract

Granite bedrock is overlain by organic-rich material in many places in the Jizera Mountains. The age of peat from two exposures in the vicinity of Josefův Důl has been established using the radiocarbon procedure. A sample taken at a depth of 1.15 m from a peat base at Peklo was dated to 7,130˝190 radiocarbon years BP (Gd-15125), suggesting that the material began to accumulate during the early Atlantic; a second sample, from a depth of 0.70, dates from the Subboreal (4,012˝155 BP; CU-1641). At Milíře, the lower of two samples taken at a depth of 0.90 m from a peat base is of Subatlantic age (2,920˝120 BP; Gd-15126); however, the site lies on the periphery of the bog, and considerably older material may be found towards its centre. An early mediaval date was determined on a peat sample taken from a depth of 0.10 m (1,550˝50 BP; Gd-11544). Detailed palynological analyses of these materials are now being undertaken.
