Important ore deposits of the chemical element, lithium, occur west of Charlotte, NC. Consider the geologic environments in which these and other ore deposits have formed. The environment for the lithium deposits has been granitic plutons in continental crust. Within this granitic rock, most of the lithium occurs within a type of
