内容記述 |
Microscopic observations of air-hydrate crystals in Vostok ice cores, Antarctica, revealed that air-hydrate crystals acted as obstacles to the grain boundary migration. About half of the air-hydrate crystals were observed to be located on the grain boundaries; their volume concentrations were more than (10)^3 times larger than dust concentration (J. R. PETIT et al., Nature, 326,62,1990). The presence of air-hydrate crystals on grain boundary was considered to reduce effectively the ice grain growth rate. However, air-hydrate crystals did not result in marked changes in grain size associated with climate transitions. |
