General comments

Subject category Comment text
Deposit ORE DEPOSITION PROBABLY OCCURRED IN MORE THAN TWO STAGES. THOSE DEPOSITS WITH EXTENSIVE TOURMALINE PROBABLY FORMED AT HIGH TEMPERATURES.
Deposit THE VEINS IN THE QUARTZ MONZONITE STRIKE N65-20E AND DIP STEEPLY SOUTH. WHEREVER THE VEINS CROSSED FROM THE QUARTZ MONZONITE INTO THE VOLCANIC ROCKS THEY CONSTRICTED INTO NARROW VEINLETS. VEINS IN THE CRETACEOUS ROCKS ARE VERY SIMILAR TO THOSE IN THE QUARTZ MONZONITE.
