Kroll - Tarfalin (continued).
If then creamy, often coarse or slightly clayey ss, sometimes more
fine but never once cemented, usually crumbling readily, the
result is great slumping in cliffs along shore and seawines. They
are easily susceptible to the influence of tides.
Course mere clay or smutty flints interlarded in
course drosses or black once a loosely carbonaceous sh.
All are thin and could seem to constitute but poor fuel.
Ordinarily would not be called coal. Fifty tons mined an-
nually for use at Omenad. There's little regularity in terms
lenses of ss, of flits, sh, interfere with regularity. Clays often
a few inches apart, sometimes separated by white or creamy
sand. In general they appear to be in two groups, (a) within
200' at the tide or the exposures of grain at tide. (b) about
400'-500' A-T. (c) about 800'. The details of stratigraphy
vary too much to make detailed sections of value to find
on considerable distances.
In general the dips 5°-15° towards the coast (N),
steepens near the shore and flattening somewhat locally
further up the seawine. A slight westerly dip is seen along
the cliff tops and it's apparent for local.
At a point about 10m E. of Tarfalain (photod) the
cret. is seen to lie along shore horizontally against a hill-
roll of reddish granite or grain, thus [illegible]
