| ore: | Cinnabar, Metacinnabar |
| gangue: | Calcite |
| orebody_fm: | POCKETS AND STRINGERS |
| work_type: | Unknown |
| alteration: | Conspicuously Lacking, Except For Supergene Oxidation Resulting In Universal Hg Minerals And Native Hg. |
| conc_proc: | Not Hydrothermal! Lessening Of T And P In The Breccia And Presence Of Carbonaceous Precipitant Encourage Deposition Fron A Pure Mercury Salt Gas. Hg Was Probably Originally Deposited With The Usual Gangue Elsewhere, Then Remobilized By Some Dynamic Action And Segregated Because Of Mercur* Low Critical T. |
| ore_ctrl: | Ns Trending Nappe-Like And Z-Shaped Folds Verge On Thrust Faults At Depth, With Gouge And Slickensides. Ore Is Localized In The Downward Opening Acute Angles Of These Folds In The Associated Breccia. An Impervious Gouge Cap Envelopes The Breccia. |
