Description

Limonite is an ore consisting of a mixture of hydrated Iron Oxide-Hydroxide of varying composition of minerals such as Goethite, Lepidocrocite, or Jarosite. It has been mined with Hematite as an Ore for the production of Iron. Limonite is heavy and has a yellow-brown color. It is often used as the pigment ochre in many paints.

Dendrites are branched or tree like inclusions, usually manganese or iron oxides that are caused by irreversible aggregation of small particles forming large cluster. Dendritic crystal growth is common and resembles a snowflake formation or frost patterns on a window. Dendritic crystallization forms a natural fractal pattern. The term “dendrite” comes from the Greek word dendron, which means “tree”. It has only been in recent years that researchers have begun to understand how dendrites form and these ideas were developed by chemists and mathematicians working in disciplines called chaos and fractal geometry. Colloidal-sized particles move in random paths in a phenomenon called Brownian motion.
