Does a porphyritic texture include two different sizes of mineral grains?

Yes, a porphyritic texture consists of two distinct sizes of mineral grains - larger crystals called phenocrysts surrounded by a finer-grained matrix called groundmass. This texture typically forms in magmas that experience two stages of cooling, resulting in the different sizes of crystals.

What are the large crystals called in an igneous rock mostly composed of a finer grained matrix?

The large crystals are called phenocrysts and the finer grained matrix is known as the groundmass. This texture is known as porphyritic texture, where the rock has two distinct crystal sizes.

This igneous texture is characterized by two distinctively different crystal sizes?

The igneous texture characterized by two distinctively different crystal sizes is known as porphyritic texture. Porphyritic rocks have larger crystals (phenocrysts) surrounded by a fine-grained matrix (groundmass), indicating two different stages of cooling within the magma.


What is the difference between borax crystals and other natural crystals?

Borax crystals are specifically composed of the mineral borax, while other natural crystals can be formed from a wide variety of minerals such as quartz, calcite, or fluorite. Borax crystals have distinct properties and chemical composition that distinguish them from other natural crystals.


What rock has large inter grown crystals in thin bands?

Gneiss is a type of metamorphic rock that often exhibits large intergrown crystals in thin bands. It forms from the transformation of pre-existing rocks under high temperature and pressure conditions, resulting in a banded appearance with distinct layers of different mineral compositions and grain sizes.


Can large crystals be found in rocks?

Yes, rocks can contain a variety of crystal sizes.


Can two distinct points both exist on two distinct lines?

No. Two distinct points define a single line.


Crystals of its salts are known for their crisp colors?

The element that has crystals of its salts, which are known for their crisp colors, is chromium. This is part of why it is commonly used for items like auto parts.
