The Andean Batholith and the Southeast Asian Tin-Belt Granites Comparedhe primary level is that of the pluton which may be internally zoned by pulses and surges of related magma. Chains of plutons of identical lithology, which have consistent intrusive relationships to other members of the batholith, are referred to as super-units. The batholithic segment consists of a
