A generalization is that minerals with metallic or adamantine lustre tend to have higher specific gravities than those having a non-metallic to dull lustre. For example, hematite, Fe 2 O 3, has a specific gravity of 5.26 while galena, PbS, has a specific gravity of 7.2-7.6, which is a result of their high iron and lead content, respectively.

How to Measure Specific Gravity of Minerals & Is It Important in Geology?

The most common equation for the specific gravity (SG) of a mineral is this: It's pretty simple to work out: 1. Weigh the mineral in air (literally put in on the scales like normal) 2. Suspend the mineral in water for the second weighing. Legend has it that is was Archimedes who discovered that the weight of the mineral in air minus its weight ...

How to Identify Minerals? - Geology Page

Specific gravity is the relative weight of the mineral to an equal volume of water. For example, gold has a specific gravity of 15-19.3 and is thus 15 to 19.3 times as heavy as water. It is possible to make a fairly good estimate of specific gravity by checking the mineral's weight in your hand. Recommended For You What is the Black Stone of Mecca?

Pure sphalerite samples can be distinguished from galena because they are harder (3.5 to 4) and have a lower specific gravity (3.9-4.1). The color of their streak provides an even simpler way to distinguish the two. A sample of galena rubbed across a rough, hard surface leaves a lead gray streak, while sphalerite's streak is white to cream colored.
