Роль содержания льда и незамерзшей воды при оценке теплопроводности вулканических пеплов (Камчатка)

Title: Роль содержания льда и незамерзшей воды при оценке теплопроводности вулканических пеплов (Камчатка)
Title, transliterated: Rolʹ soderzhanii︠a︡ lʹda i nezamerzsheĭ vody pri ot︠s︡enke teploprovodnosti vulkanicheskikh peplov (Kamchatka) / R.G. Motenko, Ė.P. Kuznet︠s︡ova.
Translated title: Role of ice and unfrozen water in the evaluation of thermal conductivity of volcanic ash (Kamchatka).
Author(s): Motenko, R. G.

Date: 2011.
Language: Russian.
In: Led i Sneg. (2011.), Vol. 2(114) (2011)
Abstract: Describes experimental study of volcanic ashes of different ages from Kluchevskaya volcano group, including phase composition of water, thermal conductivity, and granulometric and mineral composition. Refers ashes to very fine sands, with IR-spectroscopy showing presence of amorphous minerals opal and allophone. Determines dependences of unfrozen water content on temperature in range 0 to -15°C, observing no change below -3°. Unfrozen water content ranged from 0 to 10%. Reports thermal conductivity measurements made at wide range of densities and humidities, in frozen and thawed states. Assesses role of unfrozen water/ice ratio in thermal conductivity of frozen volcanic ashes and suggests use of results for estimating moraine influence on glacier melting.
