Polymorphic Mineral - No Man's Sky Wiki

Polymorphic Minerals can be further categorized by the specific number of forms each can be found in. Dimorphic Minerals [] To date, all polymorphic minerals have been found having two forms making them Dimorphic Minerals. Theoretically, should a mineral be found with three forms it would be Trimorphic, four would be Tetramorphic.

Dimorphism. Dimorphism. 1. Certain minerals and chemical substances possess the property of crystallising in two or more distinct forms. When two forms occur the substance is said to be dimorphous, and the phenomenon is known as dinwrphism; in the case of three forms, it is trimorphous, or the general term, pleomorphous, may be applied.

THE DISSOLUTION OF A COMPLEX GENETIC POLYMORPHISM:

The mid (M) morph predominated in dimorphic populations and was the only morph in monomorphic populations. Stamen modifications promoting selfing, associated with semihomostyle evolution, were largely confined to the M morph. They were rare in trimorphic populations, common in dimorphic populations, and often fixed in monomorphic populations.
