Because of its great density and because of its weak magnetic attraction, it is often mistaken for meteoritic material (see the photos above and at the bottom of the page). Crystal habit or shape: The outward appearance of single crystals is directly related to the internal arrangement of the atoms that compose a mineral. However, the common shapes you will likely encounter among common minerals in the upstate are cubic (see pyrite crystals on left below), hexagonal (see quartz crystals on right below), trigonal, pyramidal, dodecahedral, prismatic, accicular, and botryoidal. To learn how to break open and examine a geode, scroll down! Chihuahua, Mexico, where coconut geodes are mined. Almandine crystals are typically dodecahedral or trapezohedral and are red in color.

This article was co-authored by Lois Wade, a trusted member of wikiHow's volunteer community. Geodes are often formed in stratified sedimentary carbonate deposits such as limestones and dolomites.

that comes in a variety of colors (milky, clear, smoky, amethyst, rose) with crystals that are typically hexagonal in shape (often inside geodes or in veins). All images are from creative commons or are BCGM specimens. You will need to investigate streak color and crystal shape to determine what iron mineral you have found. Its crystal shape is hexagonal (6-sided) and its hardness is a 7 (out of 10 onthe Moh's scale, see below).

Geologists use a variety of characteristics to classify and identify minerals. Crystals are hexagonal and can be very large (some weighing as much as 25 tons!). Fossils are any evidence of past life including body parts such as bones, feathers, scales and leaves, or other preserved traces of behavior such as footprints, burrows and excrement.

Wind or rain could easily move dirt or sand to cover geodes. Rocks are naturally occurring combinations of two or more minerals. Hardness = 2-2.5; cleavage = perfect basal; luster = vitreous; effervescence = no; streak = usually white. For example, quartz typically does not cleave along clean planes of weakness, but fractures in what is called a conchoidal pattern (scalloped pattern in obsidian shown below).
