Platin Group Elements (PGE) Contents and Interpretation Geochemistry of Chromite Deposits with Host Rocks in Guleman (Elazığ) Region
Öz
Guleman ophiolite made up of tectonites which comprises dunite and chromite bearing harzburgites and cumulates which contain dunites, wehrlite, clinopyroxenite, gabbros, diabase dykes, sheeted dyke complex and basic volcanites are other constituents of the ophiolite. rocks samples and chromite ore sampleswere analyzed for Pt, Pd, Rh and Au using ICP-MS and for Ir and trace elements using Neutron Activation Methods. The analytical data are normalized for primitive mantle and used in spider
diagrams. These diagrams illustrate that the rocks have negative anomalies for Rh, Pt is close to mantle
values, Pd close or show enrichment and Au is enriched in comparison to the mantle. The PGE contents of
ore samples vary. Ir shows positive anomaly, Rh negative, Pt and Pd are close to or richer, and Au is
richer than the mantle values. Samples are determined as Irarsite, according to Ir ratio 45-550 wt% - Rh
ratio of 0,05-5,56 wt%- Pt ratio also 0,1-23 wt% and Chromites have the asthenospheric composition with
reference to PGE data.
