The mineral assemblage of Rhyolite is usually quartz, alkali feldspar and plagioclase (in a ratio > 1:2) and biotiteand hornblende are common accessory minerals. More importantly quartz has got to comprise more than 69% of the rock.

Does minerals that make up a rock determine how fast it weathers?
The minerals that make up a rock determine how fast it weathers to a large extent. This is mainly true when it comes to chemical weathering.

What is an example of porphyritic igneous rock?
Granite is an example of a porphyritic igneous rock. It contains large crystals (phenocrysts) within a fine-grained matrix. The phenocrysts are usually made up of minerals such as quartz, feldspar, and mica.
What kind of mineral is a rock?
A rock is composed of minerals. Minerals are naturally occurring inorganic substances with a specific chemical composition and crystal structure. Rocks can be made up of one type of mineral or a combination of different minerals.
What rocks are volcanoes made up of?
Volcanoes are made up of various types of rocks, including igneous rocks such as basalt, andesite, and rhyolite. These rocks form from the solidification of molten magma ejected during volcanic eruptions. Additionally, volcanic rocks can also contain minerals such as olivine, quartz, and feldspar.
What rock is made up of the same minerals as granite?
Rhyolite.
What elements make up the mineral rhyolite?
Rhyolite is a rock, not a mineral. Common minerals in it are quartz, orthoclase, and albite. The chief elements in rhyolite are silicon, oxygen, aluminum, sodium, and potassium with other elements in small amounts.
What has a lower density rhyolite or basalt?
Ryholite due to the reason that this rock is made up of lighter elements than that of Basalt
What is the light-colored rock that makes up most of the continental crust?
granite or rhyolite
What materials make up a rock?
Minerals and Compounds.

The particles of minerals or other rocks that make up a rock is called?
The particles of minerals or other rocks that make up a rock are called grains or crystals. These grains can vary in size and shape based on how the rock was formed and the types of minerals present within it.
Do rocks have to have minerals?
"Minerals" are the compounds that make up rocks. A rock may have several types of minerals in it. Unless a rock is composed 100% of a single element, it contains minerals.
What is rock forming minerals?
one of the common minerals that make up most of the rocks of the earths crust
What rock has a lower density basalt or rhyolite?
Basalt has a lower density compared to rhyolite. Basalt is a mafic rock with higher iron and magnesium content, which makes it denser. Rhyolite, being a felsic rock with higher silica content, is less dense.
