Definition
Arkose is a sedimentary rock, specifically a type of sandstone containing at least 25% feldspar
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

Formation
Arkose rock forms from the weathering of feldspar-rich igneous or metamorphic rock, most commonly granitic rocks, which are primarily composed of quartz and feldspar.
Marble is a metamorphic rock produced from limestone in the earth crust. It is formed by the metamorphism of limestone.
