An example of rhombic cleavage would be siderite and rhodochrosite. Remember that this is basically a "partically squashed box." Essentially, the direction of deformation in a rhombohedron occurs in one of the three diagonals that run from one corner of the cube to the other. Calcite is not a particularly fabulous example of a rhombohedron, because it is considered to be cubed.
What else can I help you with?
What is the mineral that is softer than calcite has a metallic luster and has cubic cleavage?
Pyrite is a mineral that is softer than calcite, has a metallic luster, and exhibits cubic cleavage.
An unidentified mineral that is softer than calcite that exhibits a metallic luster and cubic cleavage?
The mineral might be pyrite, which has a hardness lower than calcite, a metallic luster, and cubic cleavage. Pyrite's hardness is around 6-6.5 on the Mohs scale, compared to calcite's 3. It forms cubic crystals and has a brassy color.
What is cleavage of Galena?
Cleavage of galena is the tendency of the mineral to break along planes of weakness, resulting in smooth, flat surfaces. Galena exhibits perfect cleavage in three directions at right angles to each other, producing cubic or octahedral shapes. This property is a result of the crystal structure of galena.
What cleavage does the pyrite have?
the cleavage for pyrite is cubic
One way to test a mineral is to break it and see how many directions of what it has?

What is the mineral that is softer than calcite has a metallic luster and has cubic cleavage?
Pyrite is a mineral that is softer than calcite, has a metallic luster, and exhibits cubic cleavage.
What term is used to describe the shape of a mineral that has three directions of cleavage that intersect at 90?
The term used to describe the shape of a mineral with three directions of cleavage that intersect at 90 degrees is cubic or isometric cleavage. This means that the mineral can cleave in three directions at right angles to each other, resulting in cubic-shaped fragments.
If a mineral breaks into cubes when struck with a rock hammar which property of the mineral is getting measured?
When a mineral breaks into cubes upon being struck with a rock hammer, the property being measured is its cleavage. Cleavage refers to the way a mineral breaks along specific planes of weakness, producing flat surfaces. In this case, the cubic breakage indicates that the mineral has a cubic cleavage, reflecting its internal crystalline structure.
What mineral has a hardness of 2.5-3?
Calcite is a mineral that is white or colorless and has a hardness of 2.5 and splits with cubic cleavage.
What term is used to describe the shape of a mineral that has three directions of cleavage that intersect at 90 angles?
The term used to describe the shape of a mineral that has three directions of cleavage intersecting at 90-degree angles is "cubic" or "isometric." Minerals that exhibit this type of cleavage typically form cubic crystal systems, such as halite or pyrite. This characteristic cleavage results in the mineral breaking along smooth, flat surfaces that create cube-shaped fragments.

What is galena's cleavage?
Galena's cleavage is cubic.
Is the cleavage for a mineral always the same for that mineral?
Yes, all different samples of that mineral will have the same cleavage.
Is the cleavage for a mineral is always the same for that mineral?
Yes, all different samples of that mineral will have the same cleavage.
What are the angles at which cleavage surfaces meet in halite?
In halite, which is the mineral form of sodium chloride (NaCl), cleavage surfaces meet at angles of 90 degrees. This characteristic cubic cleavage results from the mineral's isometric crystal system, where the internal atomic arrangement allows for easy breakage along specific planes. As a result, halite typically exhibits well-defined cubic crystals with sharp edges and corners.
