Preliminary Results:
(More detailed minerology expected soon)
Phase 1 — Large, dark translucent crystals (primary fluorite)
-
REE-rich: Y, Nd, Gd, Er confirmed by XRF
-
Mn-bearing (MnO₂ detected)
-
Exhibits concentric luminescence zoning under LWUV (~365 nm): red-purple emitting core transitioning outward to blue-emitting mantle
-
Core-to-rim zonation interpreted as primary growth zoning reflecting evolution of fluid chemistry during crystallization — early fluid elevated in Mn²⁺ and LREE, transitioning to HREE-dominant with continued precipitation
-
Vuggy dissolution texture on surfaces records a subsequent dissolution event
Phase 2 — Small, fine-grained opaque crystals (secondary fluorite)
-
Nd-dominant, other REE absent or depleted
-
No Fe detected
-
UV luminescence character not yet fully assigned, but Nd³⁺ is consistent with red-orange emission under 365 nm excitation
Phase 3 — Infill material
-
Fe-rich
-
REE-absent
-
Non-fluorescent or weakly luminescent under LWUV
-
Fills void spaces created by dissolution of Phase 1
Paragenetic sequence:
Stage I → Zoned primary REE+Mn fluorite (Phase 1)
Stage II → Dissolution event
Stage III → Nd-bearing fine-grained fluorite precipitation (Phase 2)
Stage IV → Fe-rich void infill (Phase 3)
Note:The luminescence zoning in Phase 1 is the most direct evidence that the primary fluid was chemically evolving during crystallization, and separates that signal cleanly from the later overprinting events.
If you're like me and have no clue what any of this means- I've had Ai summarize the preliminary findings for different education levels:
