Textural and chemical characteristics of zircon, monazite, and thorite, Wadi Al-Baroud area, Eastern Desert of Egypt: Implication for rare metal pegmatite genesis

•Rare-metal pegmatite related to barren parent A-type granite.•Pegmatite zircon inherits its chemical fingerprint from granitic zircon.•Monazite is magmatic in the granite, but in pegmatite is S-rich altered phase.•Thorite forms solid solution with xenotime in granite and coffinite in pegmatite.•HFSE can be mobilized to the hydrothermal fluid-dominated system.
