Describe 2 physical of the mineral pyroxene?
Pyroxene is characterized by its prismatic cleavage, which typically breaks at angles of about 87 and 93 degrees, resulting in distinct crystal shapes. It often exhibits a dark green to black color and has a glassy to dull luster. Additionally, pyroxene has a hardness of about 5 to 7 on the Mohs scale, making it relatively hard compared to other minerals. Its density ranges from 3.2 to 3.6 g/cm³, contributing to its weight and compactness.
Is pyroxene a mineral or rock?
Pyroxene is a group of minerals.
Which mineral pyroxene or orthoclase crystallizes from magma first?
Usually pyroxene crystallizes from magma before orthoclase. Pyroxene has a higher melting point than orthoclase, so it will crystallize first as the magma cools and reaches temperatures where pyroxene can form.
What type of rock is made of only pyroxene and olivine?
Peridotite is made only of olivine and pyroxene
Name a coarse grained igneous rock with no pyroxene?
Granite is a coarse grained igneous rock without Pyroxene.
Does pyroxene mineral have cleavage or fracture?
Yes.
Which two minerals have cleavage planes at right angles?
halite and pyroxene
Which two minerals have cleavage planes right angles?
halite and pyroxene
How do you distinguish between olivine and pyroxene under microscope?
Olivine typically appears colorless to pale green under a microscope and has distinct cleavage patterns and high birefringence. Pyroxene, on the other hand, appears as dark to light green or brown, often showing two distinct cleavage angles at nearly 90 degrees and moderate to low birefringence. Additionally, pyroxene crystals tend to be longer and more elongated compared to olivine.
What two minerals have cleavage planes at right angles?
haltite breaks easily into distinct sheets. Also Pyroxene is another, it breaks at 90 degree angles in 2 directions.

Is pyroxene good for arthritis?
No. Pyroxene is a crystalline silicate mineral.

Usually pyroxene crystallizes from magma before orthoclase. Pyroxene has a higher melting point than orthoclase, so it will crystallize first as the magma cools and reaches temperatures where pyroxene can form.
What is sulfurs cleavage cleavage?
Sulfur's cleavage is imperfect.
What type of rock is made of only pyroxene and olivine?
Peridotite is made only of olivine and pyroxene
One way to test a mineral is to break it and see how many directions of what it has?
cleavage....
