| Deposit | THE DEPOSIT WAS PROBABLY PRECIPITATED FROM HYDROTHERMAL WATES WHICH ISSUED ALONG AN ADJACENT FAULT. THE DEPOSIT OCCURS ON THE NORTH SIDE OF THE FAULT AND IS THICKEST ADJACENT TO THE FAULT. IT IS ALSO ON OR NEAR THE INTERSECTION OF 2 RING FRACTURE ZONES. TOWARDS THE MARGINS OF THE DEPOSIT, THE HECTORITE IS MIXED WITH WHITE CALCIUM CARBONATE AND DOLOMITE, WHICH FURTHER SUGGESTS A THERMAL SPRING ORIGIN. THE BASE OF THE DEPOSIT IS IN SHARP CONTACT WITH A REDDISH, IRON-RICH AND SANDY REGOLITH DEVELOPED ON THE UNDERLYING VOLCANIC ROCKS. CARBONATES AND VOLCANICLASTIC SEDIMENTS OVERLAY THE DEPOSIT. LATERALLY, THE HECTORITE INTERFINGERS WITH CARBONATES AND HECTORITE-RICH VOLCANICLASTIC SEDIMENTS. A BED OF HIGH PURITY HECTORITE (ABOUT 1 IN THICK) OCCURS ABOUT 5 FT ABOVE THE MAIN DEPOSIT. |
