What mineral has an isometric crystal shape?
Diamond is one mineral in the isometric crystal system.
Is a triclinic crystal a mineral?
Triclinic is a crystal system that describes the geometric arrangement of atoms in a mineral. Minerals can belong to different crystal systems, such as triclinic, depending on their internal structure and external crystal shape. So, a mineral can have a triclinic crystal structure, but triclinic itself is not a mineral.
What mineral property is determined by the number and angle of crystal faces?
I believe the answer would be the crystal system, but the crystal system is based on the angles and length of the axis of the crystal. The axis length and the angle at which they meet would affact the number and angle of the crystal faces.
What is the unit cell of a mineral?
The unit cell of a mineral is the smallest repeating unit that defines the crystal structure of that mineral. It is characterized by specific dimensions and angles, which determine the overall symmetry and arrangement of atoms within the crystal lattice. The unit cell can be described using parameters such as the lengths of its edges and the angles between them, allowing for the classification of minerals based on their crystallographic properties. Understanding the unit cell is crucial for determining a mineral's physical and chemical properties.
What is a silicate with surfaces that meet nearly at right angles?
A mineral with surfaces meeting nearly at right angles is orthoclase Feldspar. It is a common silicate mineral found in igneous and metamorphic rocks. Its crystal structure forms a framework with cleavage planes meeting at approximately 90 degrees.
How do geologists use different types of crystal shapes to classify minerals?
Minerals are classified by their geometry into six different mineral crystal systems. Each crystal system has its own set of parameters based on relationships between length and angles between a crystals axes.
Which type of crystal system is also known a cubic includes diamonds and has three axes of symmetry that are at right angles to each other?
The crystal system known as cubic includes diamonds and features three axes of symmetry that are at right angles to each other. This system is characterized by its equal lengths of axes and 90-degree angles between them, resulting in shapes such as cubes and octahedra. The cubic crystal system encompasses several important mineral classes, including the isometric system.
How are crystals of minerals are classified?
Mineral crystals are divided into six distinct mineral crystal systems based on geometry and angles between axes. Crystals can further be subdivided into categories of 'habit', the crystals' variety of appearances in nature. Examples of habit are boytroidal, globular, massive, euhedral, drusy, acicular, and so on.
What are crystal form and cleavage?
Crystals come in different shapes, determined by how the molecules of compounds from which they are made can be packed together. For instance a quarts crystal is hexagonal in shape, while galena and pyrites crystals are cubic. There are six different crystal shapes or forms determined by the axes and degree of symmetry of the crystal and the angles at which the axes intersect. Subordinate to the overall crystal shapes, many crystalline substances have within them planes of weakness along which the crystal may break these lines are related to the crystals symmetry and caused by how the molecules are aligned within the crystal. This is cleavage.
How light reflects from a mineral's surfrace?
it can only reflect off a minerals surface if it had the luster of glassy, metallic or pearly if the mineral is whats called dull the darkness of that mineral cannot obsorb the light like the brighter minerals can
Is how light is reflected off a mineral's surface?
The way light is reflected off a mineral's surface is determined by its crystal structure and chemical composition. The specific orientation of the mineral's crystals affects the angles at which light is reflected, resulting in different luster and color characteristics. A mineral's surface can appear metallic, glassy, pearly, silky, or dull based on how light interacts with it.
