<p> In the summer of 1976 a study was undertaken of the Woodville/Codroy
gypsum karst plain, an area of about 4 km^2 in southwest Newfoundland.
Geology of the gypsum is revised and the general geomorphology described.
Sinkholes were surveyed and classifications based on several criteria
are presented. Hydro-chemistry is reported in some detail from field and
laboratory analyses. It is shown that the gypsum karst system evolves in
much the same \'Jay as that of limestone but at a greater rate, permitting
comprehensive study of morphologic evolution within post-glacial karst
areas. Processes at work in the gypsum may be initially simpler than
those in carbonates but complexities of rock characteristics complicate
the picture. Some water measurements indicate diffuse flow conditions in
the aquifer, while others suggest conduit flow; it is demonstrated that
both diffuse and conduit flow systems may operate in conjunction. </p> / Thesis / Master of Arts (MA)
