While the Cambrian/Precambrian unconformity is widespread, it is not universal:
"There is no angular unconformity at the base of the Cambrian, and, indeed, it
is possible that the boundary of the system lies within the Arumbera Sandstone.
this formation is a fine to medium-grained quartzose sandstone which varies in
thickness from 250 to 850 m. " ~D. A. Brown, K. S. W. Campbell and K. A. W.
Crook, The Geological Evolution of Australia and New Zealand, (New York:
Pergamon Press, 1968), p. 55.

I can't find the reference now, but Siberia and parts of Newfoundland (I
believe) have continuous deposition across this boundary.
