Subject category Comment text
Deposit DIATOMITE IS INTERBEDDED WITH TUFF AND WAS DEPOSITED DIRECTLY ON JURASSIC SANDSTONE. PREVIOUS PRODUCTION WAS FROM A 1 M THICK "PURE" DIATOMITE LAYER. THE DEPOSIT INCLUDES A 2.4 M THICK DIATOMITE BRECCIA (FRAGMENTS OF DIATOMITE, BASALT, AND LAVA BOMBS CEMENTED BY TUFFACEOUS CLAY). THIS HAS LED TO POSTULATION THAT DIATOMITE WAS DEPOSITED IN A DORMANT CRATER AND SUBSEQUENTLY FRAGMENTED BY RENEWED EXPLOSIVE VOLCANIC ACTIVITY.
