(Faculty of Science, University of Helsinki; Faculty of Earth Sciences, University of Iceland, 2020-03-20)This thesis provides insights into the petrogenesis of Iceland basalts via three subprojects. The first uses olivine macrocrysts as a proxy for mantle melting conditions below Iceland, the second utilizes petrological thermobarometry to resolve the ...
-
(Utrecht University, 2019)The paper describes two Icelandic arithmetic textbooks, published respectively in 1780 and 1911–14, both written at the beginning of an era when enhancing general education was placed on the agenda for restoring the Icelandic society after natural ...
