The problems of computer model simulation of CаO-SiO2-Al2O3 system are considered. The crystallization scheme and sets of microstructure elements are analyzed for the fields of liquidus CaO, 3CaO*SiO2, 3CaO*Al2O3. The concentration fields both with individual set of microstructure elements and the fields without the unique crystallization scheme and microstructure set were found. The crystallization stages for given compositions are illustrated by the mass balance diagrams.

The Reference Book of Ternary Oxide Systems phase diagrams computer models is presented. Its computer models of T-x-y diagrams give a possibility to calculate the mass balances at any temperature, to observe crystallization history and the process of microstructure forming at different crystallization stages. The investigation of concentration fields with the different phase constituents on the T-x-y diagram projection by means of its computer model is considered. Phase diagram of CaO-SiO2-Al2O3system is used as an example.

The Impact

<p>Glacier retreat is a key indicator of climate variability and change. Karakoram-Himalaya (KH) glaciers are the source of several perennial rivers protecting water security of a large fraction of the global population. The region is highly vulnerable to climate change impacts, hence the sensitivity of KH glaciers to regional microclimate, especially the impact of individual parameters forcing have been not quantified yet. The present study, using a coupled dynamical glacier-climate model simulation results, analyses the modelled interannual variability of mass-balance for the period 1989-2016. It is validated against available observations to quantify for the first time the sensitivity of the glaciers mass-balance to the individual forcing over KH. The snowfall variability emerges as the key factor, explaining ~60% of the variability of regional glacier mass balance. We provide insight into the recent divergent glacier response over the Karakoram Himalaya. The results underline the need for careful measurements and model representations of snowfall spatiotemporal variability, one of the HK's least-studied meteorological variables, to capture the large-scale, but region-specific, glacier changes at the third pole.</p><p> </p><p> </p><p> </p><p>Acknowledgement:</p><p>The work was supported by Indian project no.
