Exploring Mineral Properties: Characteristics and Applications

Tourmaline is known for its unique combination of fracture, hardness, luster, and crystal structure. It has a hardness between 7-7.5, metallic luster, and typically exhibits a hexagonal crystal structure.

Agate is known for its unique characteristics such as fracture pattern, hardness level of 7, non-metallic nature, and microcrystalline structure. It differs from the incorrect answers provided in terms of fracture, hardness, metallic or non-metallic nature, and crystalline structure.

Biotite is a mineral known for its cleavehardness of 2.5-3, sub metallic luster, and monoclinic crystal structure.

Halite is a mineral with a cleavage hardness of 2-2.5, non-metallic luster, and crystallizes in the monoclinic system.

Muscovite Mica is known for its cleavage, hardness ranging from 2 to 2.5 on the Mohs scale, being non-metallic, and having a monoclinic crystal structure.

Molybdenum has a cleavage hardness of 1 - 1.5 on the Mohs scale, making it relatively hard and metallic in nature, hence the correct answer.

Pyrite is known for its distinct properties which include specific hardness, luster, and crystal system. Remember that these properties can help in identifying this mineral correctly.

Galena has a cleave hardness of 2.5 and a metallic isometric crystal structure.

Garnet is known for its specific characteristics such as fracture, hardness range of 6.5 - 7.5, non-metallic properties, and isometric crystal system.

Snakeskin Agate is classified as a fracture hardness-7 non metallic microcrystalline stone, not as metamorphic igneous rock, sedimentary rock with high porosity, or metallic compound with magnetic properties.

Fluorite belongs to the isometric crystal system, has a cleavage of cleave, a hardness of 4, and a metallic luster.

Selenite has a cleave hardness range of 1.5 - 2, which indicates its relatively soft nature compared to the incorrect options mentioned.
