In addition to the minerals shown in the Graph of Changes in Mineral Composition Within the Palisades Sill, two other minerals commonly found in diabase samples are olivine and biotite. Olivine can be present in some mafic igneous rocks, while biotite is often associated with the presence of other ferromagnesian minerals. The specific composition of diabase can vary, leading to the potential for these minerals to be included in certain samples.
What else can I help you with?
What is the most common mineral in the composition of minerals?
Oxygen.
What changes the mineral composition of rock?
The mineral composition of a rock can change due to processes like metamorphism, which involves high pressure and temperatures altering the minerals present in the rock. Weathering and hydrothermal activity can also change the mineral composition by leaching out certain minerals and depositing new ones. Additionally, volcanic activity and magma intrusion can introduce new minerals into existing rocks through the process of crystallization.
Are minerals destroyed by heat?
Minerals are not destroyed by heat, but excessive heat can alter their physical and chemical properties. This can lead to changes in the mineral's crystal structure or composition. In some cases, high temperatures may cause minerals to melt or recrystallize.
How are slate and shale alike?
Dark Colour, Clay mineral composition (Kaolanite), Laminations of minerals
Which best describes the difference between a rock and a mineral?
Minerals have an unique chemical composition, and Rocks are made up of two or more minerals.
What type of weathering changes the mineral composition of rocks?
Chemical weathering changes the mineral composition of rocks by altering the chemical composition of minerals through processes like hydration, oxidation, and dissolution. This can result in the breakdown of minerals and the formation of new minerals.
What kind of weathering changes the composition of a rock?
Chemical weathering changes the composition of a rock by breaking down minerals through chemical reactions with water, oxygen, acids, or other substances. This process can alter the rock's mineral composition, leading to the formation of new minerals or the dissolution of certain minerals.
What is a rock mineral?
It is a mineral or a number of minerals which are part of the composition of rock.
What is the most common mineral in the composition of minerals?
Oxygen.

Why is a boulder not a mineral?
A mineral is a naturally occuring chemical compound. A mineral is different from a rock/boulder which can be an aggregate of minerals, or non minerals and does not have a specific chemical composition as a mineral does
What is mineral precipitation?
Mineral precipitation is the process in which minerals dissolved in water form solid mineral deposits. This can occur through various mechanisms such as evaporation, cooling, or changes in the chemical composition of the water. Examples of mineral precipitation include the formation of stalactites and stalagmites in caves.
How minerals get their colors?
The color is derived from the chemical composition of the mineral, or from staining or inclusions of other minerals.
Do minerals have chemical compositions?
Yes. Every mineral has a chemical composition.
Why the mineral of a metamorphic rock usually different from the protolith?
Remineralization can occur because of an exchange of fluids or because the squeezing out of fluids by pressure and heat create an environment where hydrous minerals cannot exist and are replaced with non-hydrous minerals.
Minerals are classified according to their .?
Minerals are classified according to their composition
Are minerals destroyed by heat?
Minerals are not destroyed by heat, but excessive heat can alter their physical and chemical properties. This can lead to changes in the mineral's crystal structure or composition. In some cases, high temperatures may cause minerals to melt or recrystallize.
