Sect: 1 Top of Section Depth(m): 886.00
LITHOLOGY: DOLERITIC BASALT;
ENTIRE CORE HAS SAME LITHOLOGY;
Piece No. : PCE NO PIECE NUMBERS ASSIGNED;
Texture : HIGH DEGREE OF CRYSTALLINITY THROUGHOUT, VISIBLE
PLAG PLATELETS 1-2MM LONG, NO OBVIOUS BREAKS INTO
DIFFERENT FLOWS ARE EVIDENT IN CORE SINCE NO
SURFACES CHILLED TO GLASS (OR FORMERLY GLASS) OCCUR,
ENTIRE CORE REPRESENTS A SINGLE THICK FLOW OR SILL;
Structure : PROMINENT CALCITE VEINS THROUGHOUT ABOUT 1CM THICK;
Alteration : SLIGHTLY MORE INTENSE WEATHERING IN UPPER PORTION
OF BASALT SECTION, MILKY-WHITE CONCENTRATIONS
SCATTERED THROUGHOUT BASALT BUT ESPECIALLY
ABUNDANT BELOW TOP 2 METERS OF CORE--GENERALLY A
FRACTION OF A MILLIMETER IN DIAMETER BUT SOMETIMES
>1MM;
Comments : LIGHT GRAY WITH SOME YELLOWISH STAIN IN UPPER PART
OF BASALT AND DARKER GRAY LOWER DOWN,
SEDIMENT/BASALT CONTACT NOT RECOVERED SO UNABLE TO
CHECK FOR SIGNS OF THERMAL METAMORPHISM OF THE
SEDIMENT CLOSE TO THE CONTACT--AS EVIDENCE OF A SILL
RATHER THAN BASEMENT FLOW, VISUAL DESCRIPTION FORMS
