C. Zhu et al., CHARACTERISTICS OF THE PERMAFROST STRUCTURE ON THE FILDES PENINSULA, KING GEORGE ISLAND, ANTARCTICA, Science in China. Series B, Chemistry, life sciences & earth sciences, 36(8), 1993, pp. 997-1010
Based on the data from the pitting, geoelectrical prospectings, temper
ature measuring, and the divided layers frost-heaving instruments, thi
s paper, first, discusses the structure features of active layers in t
his region, and proves the presence of the bowl-shaped frost table in
the stone circles area. Second, it analyses the temperature distributi
ve rule in the active layer, meantime, according to the vertical-profi
le parameters of granularity, clay mineral, salt content and resistivi
ties, it also discusses the different features of permafrost structure
and their control actions on the periglacial landform development bet
ween high and low places. It suggests that the four-layer structure sh
ould exist in the permafrost region (including under-bedrock), that is
, active layer, frost sand and gravels layer, frost volcanic rock perm
eated by sea water, and frost volcanic rock unpermeated by sea water.
Finally, the permafrost table and its vertical gradient are deduced.
