BMC Aggregates
Waterloo, Iowa
and Iowa Limestone Producers Association

Calcite with its many crystalline forms is a commonly collected mineral throughout much of Iowa. However, in its microcrystalline rock form (limestone), calcite is much less ornamental but is of critical importance as a building and construction material. More


Quartz and Calcite: Nature's Magical Minerals are Iowa’s Treasures


Sat. at 2:00 and Sun. at 2:30

Department of Earth and Atmospheric Sciences
The University of Iowa
Iowa City

Quartz is the second most abundant mineral in Earth's continental crust (after feldspar), and it occurs in two major forms, macro-crystalline quartz (including several semi-precious gemstones) and a dense, compact form called micro-crystalline quartz. More


Calcite in Caves


Sat. at 3:30
by Dr. Jeffery Dorale
Department of Earth and Atmospheric Sciences

Iowa City

Stalactites, stalagmites, and flowstones are some of the most recognizable and beautiful components of many cave systems around the world. More


Cave Formations as Climate Records


Sun. at 11:30
by Dr. Rhawn Dennison
Department of Geology
Cornell College
