Type of structure Local
Structure description Folding

Controls for ore emplacement

  • The Sandstone Is Interbedded Within The Tuff; Their Contacts Form The Loci Of The Mn Deposit. Due To Folding Of Sandstone, The Ore Body Contains Abundent Fissures, Where It Pinches And Swells. This Is Particularly True In The Saddle Portion Of The Fold. Cinnabar Has Formed As A Film Within These Fissures.
