SPITSBERGEN AND KING CHARLES ISLANDS
a major non-sequence of varying size in the Kimeridgian, cutting out
everything between the Mutabilis Zone and the Lower Volgian. This
non-sequence represents the Pseudomutabilis, Beckeri, Subplanites,
Pectinatus and Rotunda Zones of England, central Europe and south
Russia (Orenburg). Only the lower part of the Lower Volgian is present,
and the Upper Volgian has not been proved in Spitsbergen or King Charles

Islands. The next transgression began as usual with the basal Neocomian,
but in the middle of the Neocomian there is a continental phase (Weir,
1933, p. 695). It was perhaps during this phase that occurred the fissureeruptions
of basalt, in and over which are the plant-beds of Cape Flora.
The literature on the Jurassic of Spitsbergen is extensive. An excellent
general account of the geology with a coloured geological map is given by
Orvin ,(1940) and another good summary by Allan (1941). Summaries
