An analogue model of melt segregation and accumulation processes in the Earth’s crust [PDF]
Estonian Journal of Earth Sciences, 2007 An analogue experiment was carried out to model melt segregation from the solid rock matrix and its subsequent transport. Carbon dioxide gas and sand were used as analogue materials of crustal partial melt and host rock, respectively.

Link Migmatites to Granitic Body
Journal of Geography (Chigaku Zasshi), 1997 Five problems of anatexites and granites have been discussed to study the generation of granitic body. The first is that partial melting takes place in non-equilibrium conditions originated from element-transfer in crystal and from melt-migration in migmatite. Minerals in non-equilibrium relation generally coexist in a migmatite.

Deep crustal deformation by sheath folding in the Adirondack Mountains, USA [PDF]
As described by McLelland and Isachsen, the southern half of the Adirondacks are underlain by major isoclinal (F sub 1) and open-upright (F sub 2) folds whose axes are parallel, trend approximately E-W, and plunge gently about the horizontal. These large
