All of the foregoing discussion can be summarized in
a diagram (found in the accompanying folder), from which it
can be seen that the main processes which typify periglaciation
are frost and aeolian action, solifluction and subnival
plucking. Evidence of the latter, however, is inconclusive
and its ultimate product (the corrie) belongs more to the
Frost action is very extensive and ranges from pipkrake
to massive frost heaving and the productions of tors and altiplanation.benches. Features produced by frost action
are limited in altitude and governed by rock type, as
exemplified by tor analysis, which showed that the mat
conclusive results were the correlation between tor height
and altitude and their preference for coarse grained rocks.
Further research along these lines would probably be profitable.
Lithology, in the form of rock type, boulder size and shape,
amount and plasticity of soil, seems to govern the type of
patterned ground produced. Different interrelationships of
these lithological factors together with water content seem
to result in the operation of different processes. By comparing
different lithological areas, it may be possible to produce
formulae which would indicate which processes are operative.
Such a line of investigation could be of great importance to
the science of foundation engineering.
Mass movement seems to be greater in periglacial regions
than in other environments, mostly due to the predominance
of solifluction. Aeolian,.is also prominent and is responsible
for the large deposits of loess in northern France and central
Germany and other areas peripheral to the quaternary glaciation.
The denudation in the Cairngorm Mountains shows how although
aeolian erosion takes place on only a small scale, the resultant
vegetal destruction can cause extensive soil erosion.
Generally speaking, the quantitative approach in this
thesis was effective and produced results, which were not at first expected. The measurements of movement were not
successful because the period was too short or did not include
any violent weather conditions. Both quantitative,and
qualitative observations (e.g. photogrammetry), after periods
of excessive melt, should give expositive results.
