MEGACYCLITE Meaning and
Definition
-
Megacyclite is a term that encompasses two distinct meanings within different contexts. In geology, megacyclite refers to a cyclic sedimentary rock succession, typically found in older geological formations. These sedimentary rock sequences are composed of alternating layers of different rock types, such as sandstone, limestone, and shale. Megacyclites are usually characterized by their cyclical nature, where the layers repeat in a predictable pattern. This rock succession is often associated with changes in environmental conditions over long periods of time, such as variations in sea level or tectonic activity.
On the other hand, megacyclite is also used in the field of mineralogy and crystallography. In this context, megacyclite refers to a mineral with a triclinic crystal structure. Triclinic minerals possess three axes of unequal length, all intersecting at arbitrary angles. These minerals typically exhibit perfect cleavage and can appear prismatic or tabular in shape. Megacyclite minerals may also exhibit luster ranging from vitreous to pearly, and their color can vary widely, encompassing hues of white, gray, and various shades of brown.
In summary, megacyclite can refer to either a cyclic sedimentary rock succession in geology or a triclinic mineral structure in mineralogy and crystallography. The term's definition depends on the scientific discipline in which it is used.
