tindar

Meanings

1. An elongate ridge of pyroclastic palagonitic tuff, lava delta hyaloclastites, and pillow lavas common in Iceland, erupted subaqueously within an englacial lake during a subglacial volcanic fissure eruption.

Etymology

Coined by American volcanologist John Gilbert Jones in 1968, after the Icelandic word Icelandic tindur (“pinnacle, peak”), although its plural form, tindar has, since Jones' coinage, been used incorrectly as the singular.
