PHYSICAL PROPERTIES OF MINERALS

PHYSICAL PROPERTIES OF MINERALS: Influenced largely by chemical composition and atomic structure of the mineral. I. Color and Some Related Properties of Minerals Minerals are colored because certain wavelengths of light are absorbed, and the mineral color

Chemical and physical properties of minerals

Of the many optical properties of minerals, their luster, their ability to transmit light, their color, and their streak are most frequently used for mineral identification. LUSTER. The appearance or quality of light reflected from the surface of a mineral is known as luster.

Color: Mineral Properties The Mineral and Gemstone

Certain minerals exhibit a color change when exposed to light, heat, radiation, or when atomic anominalies are present. Red Realgar transforms into yellow Paraealgar upon repeated exposure to light. Some minerals, such as Proustite and Vivianite, darken upon prolonged exposure to light, whereas other minerals, such as Kunzite fade. Some minerals undergo color changes

Properties of Minerals Earth Science Visionlearning

There are many physical properties of minerals that are testable with varying degrees of ease, including color, crystal form , hardness, luster , density, and cleavage or fracture . In addition, many minerals have unique properties, such as radioactivity, fluorescence under black light, or reaction to acid.
