General comments

Subject category Comment text
Deposit DIATOMITE IS FOUND INTERBEDDED BETWEEN BASALT FLOWS. THE DIATOMITE IS UP TO 5.8 M THICK AND IS TYPICALLY INTERBEDDED WITH AS MANY AS 8 DIFFERENT TUFF BANDS. THE DIATOMITE VARIES FROM CLAY-RICH POOR-QUALITY MATERIAL ( IN 2 0.3 M BANDS) THROUGH LIGHT BROWN, LAMINATED MATERIAL TO MODERATE-QUALITY, BUFF-COLORED DIATOMITE. THE WATER CONTENT OF THE DIATOMITE VARIES CONSIDERABLY DUE TO GROUNDWATER. IN PARTS OF THE DEPOSIT, THE LOWEST SECTION IS COMPOSED OF A DIATOMITE BRECCIA (SMALL ANGULAR FRAGMENTS OF BASALT, WHITE TUFF, AND DIATOMITE). THE DIATOMITE IS OVERLAIN BY AS MUCH AS 4.6 M OF GRAY TUFF. PARTS OF DEPOSIT EXHIBIT FOLDING WITH DIPS AS HIGH AS 18 DEG. IN PLACES, THE TUFF BANDS ARE ALTERED TO BLUE-GRAY CLAY.
