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.
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.
Silicates.
The two primary minerals found in the Earth's mantle are olivine and pyroxene. Olivine is a magnesium iron silicate, while pyroxene is a group of silicate minerals containing varying amounts of iron, magnesium, and calcium. These minerals are crucial in understanding the mantle's composition and behavior, as they play a significant role in the mantle's physical properties and dynamics.

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.
no, Pyroxene is a Mineral not a rock. Rocks are made up of 2 or more minerals

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.

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.
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.
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.
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.
a metallic mineral and nonmetallic mineral thankz ^^
