Aggregates Boxed Set – 20 Specimens
Minerals do not often occur as perfectly formed Crystals. This collection aims to provide examples to illustrate terms used in describing the appearance of Crystals and their strcutures or Mineral grains.
In mineralogy and petrology, an ' aggregate ' is the term used to describe a mass of mineral crystals. The set contains 20 distinctive specimens which exhibit popular crystal forms such as acicular, bladed, dendritic, globular, tabular and much more to aid in the study of mineral forms. The set comes with a colour photo sheet on the inside of the lid detailing each of the aggregate habbits.
