Can it possible through trace element data to separate out the Zircon of Continent or crustal derived or from slab sediment input. I have bulk geochemistry data of rock.
Sediments are derived from the continental crust by crustal reworking processes such as weathering, erosion, transportation, and deposition. Especially, terrigenous sediments which are derived from reworking process of continental crust. In such case, distinguishing continental crust zircon from slab sediment is difficult. Infact, there no point to distinguish since they mean the same. There are volcaniclastic sediments that are derived being from proximal volcanic zone. However, zircon in volcaniclastic /pelagic/biogenic sediments are extremely rare.
