The 1.79 Ga Särkilahti leucogranite – a horizontal magma layer below granulite-grade migmatites in SE Finland [PDF]
Bulletin of the Geological Society of Finland, 2019 The heterogeneous, peraluminous Särkilahti garnet-cordierite leucogranite occupies ~ 75 km2 area in Svecofennian granulite-grade terrain of SE Finland. Country rocks are metasedimentary garnet-cordierite-biotite migmatites with some orthopyroxenegarnet ...

Recrystallization and Melting of Partially Melted Stark Rubber
Rubber Chemistry and Technology, 1967 Abstract Two specimens from a piece of stark rubber which had a melting temperature originally at 41° C were partially melted at 38° C and allowed to stand for 11 years, one at about 25° C, the other at 38° C. The first showed a continuous slow decrease in specific volume, while the second increased slowly in volume for 5 months and remained ...

Spontaneous small‐scale melt segregation in partial melts undergoing deformation [PDF]
Geophysical Research Letters, 1989 A partial melt undergoing large scale deformation is shown to be unstable with respect to small scale redistribution of melt, provided the shear viscosity of the matrix depends on melt fraction. In the physically realistic case where melt “softens” the matrix, melt migrates along the direction parallel to the axis of minimum compressive stress and ...

Melting and freezing of argon in a granular packing of linear mesopore arrays
, 2008 Freezing and melting of Ar condensed in a granular packing of template-grown arrays of linear mesopores (SBA-15, mean pore diameter 8 nanometer) has been studied by specific heat measurements C as a function of fractional filling of the pores.
