Definition
Marble is a non-foliated metamorphic rock which is composed of recrystallized carbonate which is formed when limestone is exposed to high temperatures and pressures over a long time
Amphibolite can be defined as a granular metamorphic rock which mainly consist of hornblende and plagioclase

Formation
Marble is a metamorphic rock produced from limestone in the earth crust. It is formed by the metamorphism of limestone.
Amphibolite is a coarse-grained metamorphic rock which forms by metamorphism of mafic igneous rocks like basalt and gabbro or from the metamorphism of clay-rich sedimentary rocks like marl or graywacke.
