Finite lattice distortion patterns in plastically deformed zircon grains
Summary: Three types of lattice distortion patterns in deformed zircon are detected: (I) gradual bending of the crystal lattice without subgrain boundaries, (II) local gradual bending of the lattice with formation of semicircular subgrain boundaries, and (III) strain-free subgrains separated by subgrain boundaries. The difference is controlled by strain rate and differential stress. Activation of energetically preferable slip systems is facilitated by decoupling from matrix and/or by soft host mineral.
Using the level set method in geodynamical modeling of multi-material flows and Earth's free surface
Summary: Our paper demonstrates that the level set method is a viable method for material tracking in multi-material flow models. The different benchmarks illustate several advantages that the level set method provides over tracer-based methods. We therefore conclude that the level set method is well suited for geodynamical modeling.
Analysis of land cover change and its driving forces in a desert oasis landscape of Xinjiang, northwest China
Summary: In this paper, we present research on the spatial-temporal pattern of land cover change in the fragile ecosystem of the arid desert oasis of Hotan in northwest China. Multi-temporal Landsat images were used to analyze the land cover change and to identify change trajectories. The natural and human driving forces of these changes were examined using hydro-climatic data and socio-economic data.
