3 Minerals – An Introduction to Geology

3.2 Formation of Minerals Minerals form when atoms bond together in a crystalline arrangement. Three main ways this occurs in nature are: 1) precipitation directly from an aqueous (water) solution with a temperature change, 2) crystallization from a magma with a temperature change, and 3) biological precipitation by the action of organisms.

Hematite

2018/4/26Hematite is dense and hard, it is the most important ore of iron because of its high iron content and its abundance. The mineral occurs in various habits: steel-gray crystals and coarse-grained varieties with a brilliant metallic luster are known as specular hematite; thin, scaly forms make up micaceous hematite; and crystals in petal-like arrangements are called iron roses.

10 Minerals That Have Metallic Luster

2019/9/2The 10 minerals that have metallic luster are a rarity among minerals, and that's why some are considered to be so valuable. Luster, the way a mineral reflects light, is the first thing to observe in a mineral. Luster can be bright or dull, but the most basic division among the various types of luster is this: Does it look like a metal or not? Get price
