The Density of Common Rocks and Minerals

 · As a general rule, non-metallic minerals have low densities while metallic minerals have high densities. Most of the major rock-forming minerals in the Earth''s crust, like quartz, feldspar, and calcite, have very similar densities (around 2.6 to 3.0 g/cm 3). Some of the heaviest metallic minerals, like iridium and platinum, can have densities ...

More on identifying rocks & minerals

Limestone is composed of calcium carbonate (CaCO 3), thought to originate from the carbonate-based shells and skeletons of tiny sea creatures. Limestone can range from chalk-white all the way through dark gray to almost black. This dark limestone looks like basalt or "traprock" at first glance, but it is much softer and is easily attacked by acids.

Feldspar: The Potter''s Pet Rock

 · Feldspars are minerals of varying composition commonly used by potters. Feldspars form a glassy, white surface when fired high enough. They have a very long range, they begin melting at cone 4 and continue fusing beyond cone 10. They also tend to stiffen a glaze due to their high alumina content. In ceramics there are two basic categories of feldspars: potash feldspars, in which the …

feldspar (KAlSi 3O 8) is believed to be too slow to provide agronomic benefits. Using limestone (CaCO 3) and/or dolomite (CaMg(CO ) 2) as the additives, crystalline struc-ture breakdown of potassium feldspar is achieved by high‐temperature treatment and a K‐containing multi‐nutrient silicate fertilizer is thus produced.

The high SiO 2 contents of loess deposits reflect a dominance of quartz, but smaller amounts of feldspars and clay minerals also contribute to this value. Plots of SiO 2 versus Al 2 O 3 show that most loess has a composition that falls between that of average shale and quartz-dominated sandstone ( Muhs and Bettis, 2003 ).
