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.
What else can I help you with?
Does pyroxene have cleavage?
Yes, pyroxene exhibits two distinct cleavage planes at nearly right angles to each other. The cleavage of pyroxene is considered good in one direction and poor in the other.
What are 2 elements that can be found in both olivine and pyroxene?
Silicates.
List four steps that are required to separate an element from the ore in which it is found?
1. get a mineral 2. separate mineral from ore 3. seperater ore from mineral 4. record observation
What are the physical properties of halite?
Halite, or sodium chloride, is a colorless or white mineral with a glassy luster. It typically forms cubic crystals and has a hardness of 2.5 on the Mohs scale. Halite is water-soluble and has a salty taste.
Is topaz inorganic yes or no?
Yes, topaz is considered an inorganic mineral. It is a silicate mineral composed of aluminum and fluorine, with the chemical formula Al2SiO4(F,OH)2. As a naturally occurring mineral, it does not originate from biological processes.
Can pyroxene ever be a sedimentary rock?
no, Pyroxene is a Mineral not a rock. Rocks are made up of 2 or more minerals

What is mineral oil and what are its physical properties and its formula?
Mineral oil is a clear, odorless, and colorless liquid derived from petroleum. It is composed of a mixture of alkanes and cycloalkanes. Its physical properties include being lightweight, non-comedogenic, and having a high boiling point. The general formula for mineral oil is typically CnH2n+2, where n represents the number of carbon atoms in the alkane chain.
What is the chemical formula for Gabbro?
Gabbro rock is in the same family as Basalt rock and there for has similar chemical composition. Basalt is nearly half composed of silica and has other minerals in much smaller percentages such as titanium dioxide, iron oxide, aluminum and magnesium.
What are four elements of a mineral?
Four elements of a mineral are: 1) chemical composition, 2) crystalline structure, 3) physical properties (such as color, hardness, and luster), and 4) naturally occurring inorganic solid.
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 is the source of mineral fragments in soil?
Mineral fragments in soil come from the weathering and breakdown of parent rock material over time. Physical, chemical, and biological processes break down larger rock particles into smaller mineral fragments, which become part of the soil composition. These mineral fragments provide essential nutrients for plants and help determine soil properties.
What are the 2 kinds of minerals?
a metallic mineral and nonmetallic mineral thankz ^^
What is the 2 meaning of hard blow?
A hard blow can refer to a physical impact or strike that is strong and forceful. It can also describe a significant setback or difficulty that someone faces, typically in a non-physical context.
