Minerals are not equivalent to rocks. A rock is an aggregate of one or more minerals or mineraloids. Some rocks, such as limestone or quartzite, are composed primarily of one mineral – calcite or aragonite in the case of limestone, and quartz in the latter case. Other rocks can be defined by relative abundances of key (essential) minerals; a granite is defined by proportions of quartz ...

In 1936, Harold Lattimore Alling defined cleavelandite as a triclinic mineral, suggesting a difference from true albite as well as "analbite". Fisher (1968) studied cleavelandite from Chesterfield, Massachusetts, USA, the type locality ...
