Registration via the link below is required in order to receive the zoom meeting invitation and/or access the recording, which will become available after the meeting. *IAVCEI/IACS VIIC Seminar: Tuya Talks by Alastair Hodgetts and Ben Edwards* 14th September, 2021 | 6a PDT | 9a EDT | 2p BST | 10p JST | 3a HST Alastair Hodgetts | University of Birmingham | The Thórólfsfell tuya, South Iceland â?? A new type of basaltic glaciovolcano This talk will examine the first description and interpretation of Thórólfsfell, a basaltic tuya on the southern flank of Tindfjallajökull central volcano, S. Iceland. This asymmetrical, effusion-dominated glaciovolcano is constructed of an unusual set of lithofacies, unlike other tuyas described elsewhere, and displays no evidence for substantial and sustained meltwater accumulation. The atypical eruptive and glacio-hydrological conditions responsible will be explored and comparisons to other effusion-dominated tuyas (in Iceland and elsewhere) will allow us to question whether effusion-dominated tuyas are perhaps more diverse and varied than currently thought? A criterion for identifying other Thórólfsfell-type tuyas will be outlined and compared and contrasted to the â??classicâ?? tuya model. Ben Edwards | Dickinson College | Trouble with tuyas? Some thoughts on scholarship and definitions for the â??newâ?? science of glaciovolcanism Although scientists in the early 1900â??s first recognized that some volcanic deposits in Iceland and British Columbia likely formed by volcano-ice interactions, definitions and classifications for these curious deposits have followed more slowly. For example, the now-standard term â??glaciovolcanismâ?? was only first used in a publication in 2002. We will briefly discuss the history of a few of these terms and classifications with a special focus on better understanding the origins of the word â??tuyaâ??, and whether or not it should be used as a general synonym for â??subglacial volcanoâ??. You are invited to a Zoom meeting.
