描述Layered Websterite in Basement Sill in McMurdo Dry Valleys in Antarctica.jpg |
English: Layered websterite in Basement Sill in McMurdo Dry Valleys in Antarctica.
Small scale, rhythmic layering in the LZ websterite comprising thin bands of plagioclase dispersed within a predominantly Opx matrix. Model-derived shear strain rates for congested magma where crystal loads exceed approximately 30% are comparable with experimental evidence for shear-thinning in congested magmas. The implication is that the feldspar-rich layers formed by dilation in the magma slurry during emplacement. |
