Crystallization of Magma. CEGS Programs Publication Number 14.
Berry, R. W.
Crystallization of Magma is one of a series of single-topic problem modules intended for use in undergraduate geology and earth science courses. Through problems and observations based on two sets of experiments, this module leads to an understanding of how an igneous rock can form from molten material. Environmental factors responsible for important variations observed in magnetic rocks are stressed. Two fundamental factors affecting or controlling the mineral composition and texture of the resulting rock (initial magma composition and cooling rate) are also stressed. In addition, reasons why scientists classify materials in general and how they classify rocks in particular are explored. However, the ability to name or identify rocks is not a necessary result of attaining the module's goals. Supplemental questions included at the end of the module may prove difficult for the average non-major; they are intended to challenge the superior student. Like other modules in the series, this module is inquiry- and problem-oriented, dealing with interdisciplinary, contemporary, and pragmatic aspects of the subject matter. It is designed to be open-ended so that ideas can be incorporated into higher level classwork. (Author/JN)
