IndoorCampus Feature FNR Hardwood – Yellow Poplar Liriodendron tulipifera Summary Yellow-Poplar, or Liriodendron tulipifera L., is an abundant tree which causes the wood to be inexpensive. The wood is used for functional parts and decorative parts. The sapwood is very wide and white, and may receive a grey cast due to processing. The heartwood is light yellow to greenish color which will change to a light to dark brown color. Old growth material can have a very green color, but will lose…
Campus Feature Fountain-High Grade Gneiss Amigmalite Part of the EASP Geology Walk Information needed Department of Earth, Atmospheric, and Planetary Sciences
Campus Feature Gneiss Part of the EASP Geology Walk Gneiss is a metamorphic rock formed by changing schist, granite, or volcanic rocks through intense heat and pressure. Gneiss is foliated, which means that it has layers of lighter and darker minerals. These layers are of different densities and come about as a result of the intense pressure used to form gneiss. Gneiss is made up of coarse-grained minerals such as quartz and feldspar. Department of Earth, Atmospheric, and…
Campus Feature Granite Part of the EASP Geology Walk Granite is an intrusive igneous rock formed deep in the earth. When magma cools, minerals within it form crystalline grains. On the earth’s surface lava cools quickly to form small crystalline grains (and therefore rocks such as rhyolite), but beneath the surface of the earth, magma takes a much longer time to cool. This allows the minerals to develop into much larger grains. Rocks with these larger grains are…

Campus Feature Hornfels Part of the EASP Geology Walk Hornfels is a metamorphic rock formed by a special type of metamorphism called contact metamorphism. This means that a rock (clay rich in this case) comes into contact with an igneous intrusion so the rock heats up but no pressure is exerted. Because of this, hornfels is nonfoliated; there is no pressure to force the minerals into layers. Hornfels can vary widely in both appearance and mineral composition, which…
Campus Feature Hovde Hall – Limestone Pillars and Granite Steps Part of the EASP Geology Walk Limestone is a popular material to use in the construction of buildings. Its weight prevents it from being used in construction of extremely tall buildings, but it is easy to cut into blocks and will stand up well to exposure. Indiana is the source of most of North America’s limestone. Granite is also a popular construction material, but it is used mainly in items such as flooring tiles, kitchen…
