Gravity fractionation occurs during the early stages of magmatic crystallization when the magma is still dominantly liquid and crystals can sink through it to accumulate at the base of the magma chamber or interlayered with other early-formed minerals.  2, record 1, English, - early%2Dformed%20mineral

Lorsque les cristaux sont bien individualisés, le minéral est dit automorphe; dans le cas contraire (pas de forme propre), [il] est dit xénomorphe. Le premier cas correspond aux minéraux qui cristallisent précocement, ils peuvent alors développer leurs formes propres, le second aux minéraux plus tardifs qui remplissent les espaces laissés libres par les premiers.  3, record 1, French, - min%C3%A9ral%20pr%C3%A9coce

The plagioclase in oxide gabbro bodies is euhedral to subhedral, whereas the augite and magnetite are subhedral to anhedral. This implies relatively early crystallization of plagioclase, in contrast to its late crystallization in the ultramafic bodies.  1, record 2, English, - early%20crystallization

Low-pressure crystallization : At 1 atm [atmosphere], the first phase to crystallize is Cr-rich spinel, immediately followed by olivine. Olivine and Cr-rich spinel cocrystallize until about 25 weight percent(about 20 volume %) olivine is formed, then plagioclase and pigeonite join the crystallizing assemblage. Experimental results thus suggest that low-pressure crystallization will lead to early crystallization of about 20 volume % of olivine phenocrysts before crystallization of a pyroxene + plagioclase + olivine groundmass.  6, record 3, English, - low%2Dpressure%20crystallization

If the growth rate for plagioclase were much greater, this mineral could crystallize almost completely before the pyroxene substantially developed. Such a phenomenon could not develop under equilibrium conditions where cotectic(simultaneous) crystallization of both phases would occur at a very early stage.... The observation that [the ophitic] texture is normally absent in coarser gabbros of the same composition that have cooled very slowly supports this hypothesis, as does the fact that it is pyroxene rather than plagioclase that is generally observed to have separated prior to cotectic precipitation during fractional crystallization of differentiated tholeiitic sills...  3, record 5, English, - cotectic
