Definition

A tindar is a linear, constructional, often serrated ridge, mainly composed of bedded lapilli tuff (Jones1969; Smellie2000).

Category

A type ofsubglacial volcano;linear ridge type.

Synonyms

Hyaloclastite ridge;palagonite ridge;móberg ridge;tephra mound

Description

A linear ridge in which the slopes of the flanks are generally somewhat steeper than the angle of repose due to rapid lithification of the unconsolidated lapilli tuffs and the buttressing effects of former enclosing ice (Smellie2013). A cone may be formed if the eruptions are from a central source, but in that case it should probably be simply called a tuff cone or tephra mound rather than tindar (hydrovolcanic feature). However, Smellie (2000) referred to a “tindar stage” of evolution of subglacial volcanic edifices that encompasses both ridge and tuff cone landforms. If a capping lava is present and it develops into a lava-fed delta, the edifice becomes known as a tuya (Mathews1947; Jones1969) (tuya). “Móberg...
