Economic information

Controls for ore emplacement

  • The Ore Deposits At Raura Were Formed By Both Fissurefilling And Replacement. In Most Cases Ore Was Deposited By Simple Fissure Filling With Little Or No Replacement. However,In Areas Of Unaltered Or Only Slightly Metamorphosed Limestone,Many Vein-Like Deposits And A Few Mantos Were Formed By Replacement Of Limestone Along The Bedding.

Comments on the geologic information

  • DETAILS OF THE GENERAL GEOLOGY OF THE AREA HAVE BEEN LARGELY OBSCURED BY SUCCESSIVE IGNEOUS INTRUSIONS AND ALTERATION OF THEIR HOST ROCKS. FOLDED LIMESTONE OF PROBABLE CRETACEOUS AGE WERE COVERED BY RHYODACITE FLOWS AND TUFFS. SUBSEQUENTLY THESE ROCKS WERE INTRUDED BY A SERIES OF GRANODIORITE AND QUARTZ MONZONITE STOCKS. ADDITIVE CONTACT METAMORPHISM OF THE INTRUDED ROCKS AND ORE DEPOSITION ARE RELATED TO THESE INTRUSIONS. THE PREDOMINANT ROCK IS A THICK-BEDDED FINE-GRAINED BLACK LIMESTONE,NONFOSSILIFEROUS.
