Significados de groundmass em inglês

However, we still find some happy in the groundmass between the mineral grains.

Pyroxene, quartz and augite form the groundmass, as seen in section.

Clear brown glass with many small crystals of plagioclase and pale brown augite (hyalopilitic groundmass) is very frequent in pyroxene-andesites.

The hornblende- and mica-andesites have groundmasses composed mainly of acid plagioclase with little orthoclase or glassy base (pilotaxitic groundmass).

In the dacites felsitic groundmasses are by no means rare, but microcrystalline types consisting of plagioclase and sanidine with quartz are more prevalent.
