years ago (Walker, 1995). His paper begins by re-
calling the Geikie-Judd controversy around 1890 re-
garding the nature of the volcanism in the British Ter-
tiary Volcanic Province. This controversy did in fact
have some connectionswith research in Iceland at that
time (cf. Kristjánsson, 1995). Walker then goes on
to discuss the historical and the modern findings on
the North Atlantic volcanism, and suggests renewed
efforts to resolve outstanding points. This paper is in-
deed characteristic of George Walker, demonstrating
both his solid roots in classical traditions of British
geology and his constant search for new approaches
in the field of research to which he was so devoted.
A partial bibliographical list of papers by
George Walker on Iceland’s geology and some re-
lated subjects up to around 1980 is accessible at
www.raunvis.hi.is/∼leo. The list also includes vari-
ous papers by his graduate students, as well as some
joint papers by Walker and others based on his geo-
logical mapping in Iceland.
ÁGRIP
George P.L. Walker og jarðfræðirannsóknir hans
á Íslandi
Grein þessi hefst á minningarorðum sem höfundur
flutti á fundi í Vísindafélagi Íslendinga 23. feb. 2005,
um dr. George P.L. Walker jarðfræðing (1926–2005)
sem var bréfafélagi þess félags. Rætt er þar stutt-
lega um helstu verkefni í þeim rannsóknum Walk-
ers sem hann stundaði á Íslandi frá 1955, og nefnd
ýmis svið jarðfræði Íslands þar sem ritverk hans
höfðu mjög mikil áhrif. Í greininni eru síðan rifjuð
upp persónuleg kynni höfundar af George Walker og
af öðrum vísindamönnum sem tengdust rannsóknum
hans hér. Bent er á vefsíðu þar sem finna má skrá um
margar áhugaverðar ritsmíðar Walkers, nemenda hans
og samstarfsmanna, sem birtust á árabilinu frá 1950
til um 1980.
