چکیده انگلیسی
This investigation of leached caps in Meiduk and Parkam porphyry copper deposits (PCD) in Kerman Cenozoic magmatic arc (KCMA) of SW Iran indicated that the fertility of supergene enrichment zones may be inferred from the mineralogical and geochemical characteristics of their associated leached caps. That is, the indigenous mature leached caps characterized by strong leaching of Cu, large ion lithophile elements (LILEs), and high field strength elements (HFSEs), commonly form above intrusions where supergene enrichment is strongly developed. Mineralogically, these leached caps (e.g., SE Meiduk) are characterized by abundant hematite and minor goethite (Hem:Gtâ¯ââ¯5.48), whereas immature leached caps (e.g., NW Meiduk and Parkam) are associated with poorly developed supergene enrichment zones characterized by abundant goethite (Hem:Gtâ¯ââ¯0.56 for NW Meiduk and 0.38 for Parkam), boxwork textures, secondary copper minerals and remnant pyrite. Calculated rock quality designation (RQD) from drilling cores in Meiduk deposit also revealed the relation between joint density and the extent of supergene enrichment. Moreover, increasing the rare earth elements (REEs) content in the immature and fewer REEs concentration in the mature leached caps also reflects the fertility of supergene enrichment zone in PCDs.
