The oriented attachment and adherence of individual crystals to form a heterogeneous crystalline edifice is termed synneusis, from the Greek syn (together) and neusis (swimming). Depending on the nature of the individuals and their relative orientation, the result can be a parallel growth, a twin, an allotwin, a plesiotwin or an epitaxy.
The term was introduced in petrology to describe the oriented attachment and adherence of minerals segregated from a magma at an early stage.
