9.1: Specific Gravity - Geosciences LibreTexts

Since specific gravity is relative to the weight of an object in air and its weight in water, it is a ratio and isn't expressed in units (such as kg/m³). For instance, the SG of Diamond = 3.52 (whereas the density of Diamond = 3.52 g/cm³). In gemology, specific gravity is, usually, determined through an apparatus based on Archimedes' Principle.

feldspar | Properties, Uses, Types, & Facts | Britannica

Feldspar, any of a group of aluminosilicate minerals that contain calcium, sodium, or potassium.Feldspars make up more than half of Earth's crust, and professional literature about them constitutes a large percentage of the literature of mineralogy.. Of the more than 3,000 known mineral species, less than 0.1 percent make up the bulk of Earth's crust and mantle.

Plagioclase - Wikipedia

Plagioclase is a series of tectosilicate (framework silicate) minerals within the feldspar group. Rather than referring to a particular mineral with a specific chemical composition, plagioclase is a continuous solid solution series, more properly known as the plagioclase feldspar series (from the Ancient Greek for "oblique fracture", in reference to its two cleavage angles).

The Density of Common Rocks and Minerals

Jan 23, 2020· The densities of rocks and minerals are normally expressed as specific gravity, which is the density of the rock relative to the density of water. This isn't as complex as you may think because water's density is 1 gram per cubic centimeter or 1 g/cm 3. Therefore, these numbers translate directly to g/cm 3, or tonnes per cubic meter (t/m 3).

Feldspar - Identification of specific feldspars | Britannica

Feldspar - Feldspar - Identification of specific feldspars: Alkali feldspars can often be distinguished from plagioclase feldspars because most grains of the latter exhibit albite twinning (see above Crystal structure), which is manifested by parallel lines on certain cleavage surfaces, whereas grains of alkali feldspars do not. This criterion is not, however, absolute; some plagioclase ...

THE ROLE OF PARTICLE SIZE AND SOLID CONTENTS OF FEED …

When there is a marked difference in particle shape, the concentration criterion, which is the density of the heavy species minus the density of suspending fluid, divided the density of light species minus density of suspending fluid, approaches 1.0. Typical of this is the separation of mica from quartz and feldspar (Browning, 1973).

Mineral Identification | Earth Science

Gold has a density of about 19 g/cm 3; pyrite has a density of about 5 g/cm 3 – that's another way to tell pyrite from gold. Quartz is even less dense than pyrite and has a density of 2.7 g/cm 3. The specific gravity of a substance compares its density to that of water. Substances that are more dense have higher specific gravity. Hardness

Gemstone Specific Gravity (density)

Density, or specific gravity, is a bulk property of a mate­ rial that is independent of direction and is uniform within a mass of material under ideal circumstances. In actuality, the density of a mineral varies widely, even within a single crystal, due to the presence of impu­ rities, cracks, and bubbles. Density is a useful parameter in gem identification, so the problems in its determina ...
