The article attempts to describe the geological history of the early earth through the examination of igneous zircons. According to the author, zircons are the oldest minerals on earth, dating as much as 4.4 billion years ago. Several studies have been performed in order to analyze the geochemistry of the said mineral in order to generate significant information regarding the conditions on early Earth as well as the composition of its early crust. Further information regarding the relativity of the minerals to the earth's geologic history is provided.
