University of Minnesota's Mineral Pages: Olivine

No crystal masses of olivine occur in the Minnesota region, but olivine minerals are important components of the basalt and gabbro rock units that make up the North Shore of Lake Superior. Outcrops of these rocks also extend along the St. Croix River Valley, from the Lake Superior area down to Interstate Park on the Minnesota-Wisconsin border.

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).

OLIVINE (Magnesium Iron Silicate)

Olivine is actually a name for a series between two end members, fayalite and forsterite. Fayalite is the iron rich member with a pure formula of Fe 2 SiO 4. Forsterite is the magnesium rich member with a pure formula of Mg 2 SiO 4. The two minerals form a series where the iron and magnesium are substituted for each other without much effect on the crystal structure.
