F. Rogers’s system, published in 1935, is commonly used in the United States (Box 10-3). Consider a crystal shaped like a shoe box (Figure 10.29). It contains three pairs of identical faces (opposite sides of the crystal). So, the crystal contains three forms.

Recognizing the habit can aid in mineral identification and description, as the crystal habit is an external representation of the internal ordered atomic arrangement. Most natural crystals, however, do not display ideal habits and are commonly malformed. Hence, it is also important to describe the quality of the shape of a mineral specimen: • Euhedral: a crystal that is completely bounded by its characteristic faces, well-formed. Synony… WebThe crystal habit represents the geometric appearance of the crystal, which could be acicular, tabular, or striated, which is determined by length, width, and numbers of crystal faces. Various combinations of numbers of crystal faces are defined by morphology. Thus, crystals with identical morphology can have different habits. eastern shore center for independent living https://louecrawford.com
