This means they are older than the groundmass.
The grain size of the groundmass stays in the 5 millimeter range.
When a rock cools too quickly the liquid freezes into a solid glass, or crystalline groundmass.
The microgranite is porphyritic with a very fine groundmass.
Consequently, it is possible that alteration is responsible, at least in part, for these unusual groundmass compositions.
It is possible that the groundmass 'trend' noted by and is an artefact?
Alkali feldspar is found only in the groundmass, sometimes associated with myrmekite.
The alkali feldspar is confined to the groundmass.
The most important criterion is the phenocryst species, followed by the groundmass mineralogy.
They consist essentially of olivine and augite with a brownish glassy groundmass.
Mesocumulates are rocks with between 93-85% accumulated minerals in a groundmass.
Porphyroclasts are fragments of the original rock before dynamic recrystallisation produced the groundmass.
The groundmass of these rocks is composed of plagioclase and quartz.
Alkali feldspar occurs interstitially also in the fine- to medium-grained groundmass.
Clavulinopsis has an free aggulinated test with a considerable calcareous groundmass.
Groundmass of rock is the fine-grained mass of material in which larger grains or crystals are embedded.
Aphanites are commonly porphyritic, having large crystals embedded in the fine groundmass or matrix.
The groundmass minerals usually have a grain size of 5 millimeter, which is slightly higher than in the common facies.
Often, where the groundmass is aphanitic, chemical classification must be used to properly identify a volcanic rock.
Cracks have been filled with opaque minerals, bigger fractures are in-filled with groundmass material.
Cumulates are named according to their dominant mineralogy and the percentage of crystals to their groundmass(Hall, 1996).
Occasionally some individual crystals (phenocrysts) are larger than the groundmass, in which case the texture is known as porphyritic.
Tholeiitic rocks may have a fine, glassy groundmass, as may other types of basalt.
So there is an important contrast here between the groundmass of tiny, felted crystals and the much bigger, separate phenocryst minerals.
Unlike most volcanic rocks, obsidian does not contain phenocrysts; it is, so to speak, all glassy groundmass.
The matrix would have to be turned on its side.
Let the matrix do the work, he tried to tell himself.
At some time someone had said, Look into the matrix.

The form of the matrix is shown in Table 10.1.
"What does he think the matrix will do to him?"
That's going on all around you, in the matrix itself.
Now look at the line running from top to bottom of the matrix.
Clearly, this was not even like being within a matrix.

The data became part of his matrix within seconds, as always.
The matrix had potential to be read in any direction.
And there was only one way to do that: his matrix.
His hand went out toward the matrix on my neck.
"How did you learn that my father was a matrix?"
The results are often presented in the form of a matrix.
A matrix has its design in the same sense as a die.
So how could you figure the whole matrix had a particular shape?
But we also learned that anything was possible in the Matrix if you could "free your mind."
