LITHOLOGY: BASALT AND BASALTIC PILLOW BRECCIA AND SEDIMENTS;
           INTERVALS (0-25) AND (55-98) IS BASALT, INTERVALS
           (25-55) AND (98-150) IS BASALTIC PILLOW BRECCIA;

  Piece No.  : PCE NO PCE NUMBERS ASSIGNED;

  Texture    : BASALT IS APHANITIC, DARK GRAY GLASSY BASALT AT
               LOWER CONTACT OF INTERVAL (55-98);

  Structure  : INTERVAL (55-98) PROBABLY A PILLOW;

  Alteration : WEATHERED GRAY BROWN (2.5Y 5/2);

  Comments   : INTERVAL (0-25) HAS LOCAL PATCHES OF HARDENED
               SEDIMENT AND LOCALLY SOFT SEDIMENTS ATACHED TO
               IRREGULAR WEATHERED SURFACE, INTERVAL (25-55) IS
               BRECCIA WITH ANGULAR FRAGMENTS UP TO 5MM LONG,
               WEATHERED GRAY BROWN AND BROWN, MARBLE PRESENT
               BETWEEN BRECCIA FRAGMENTS, WITH CALCITE XTLS GROWING
               ON THE WALLS OF DRUSES, THE LOWER CONTACT IS A VERY
               DARK GRAY GLASSY BASALT, INTERVAL (55-98) IS
               BORDERED BY CONTACTS INCLINED STEEPLY TO HORIZONTAL
               (60 AND 35 DEGREES), INTERVAL (98-150) IS BROKEN
               (43-120 AND 130-134 AND 140-155CM INTERVALS),
               UNBROKEN PARTS SHOW THAT THE INTERVAL CONSISTS OF
               PILLOW BRECCIA WITH ANGULAR FRAGMENTS UP TO >10CM
               LONG WITH INTERSTICES FILLED WITH XTLN CALCITE
               WHICH MAY REPRESENT METAMORPHOSED SEDIMENTS, BLACK
               GLASSY BASALT CHIPS ABOUT 1CM LONG ARE PRESENT, FOR
               MORE INFORMATION REFER TO THE SITE 19 CHAPTER OF
               THE INITIAL REPORTS;

  Vesicles   : VESICLES ARE FILLED, AMYGDULES WEATHERED BROWN;

  Replacement: CALCITE

  Comments   : PCE 1 IS BASALT PILLOW BRECCIA, NEARLY VERTICAL
               CONTACT BETWEEN PCES 1 AND 2, PCE IS IS PILLOW
               BASALT WITH PILLOW PILLOW BRECCIA IN CALCITIC
               MATRIX, WITH FRAGMENTS UP TO 5CM OF BASALT AND OF
               BLACK GLASS, BETWEEN PCES 2+3 CONTACT WITH BLACK
               GLASS CHILLED MARGIN, PCE 3 IS A WORK SAMPLE-MAINLY
               PILLOW BASALT, WITH PILLOW BRECCIA, PCES 4+5 ARE
               MAINLY PILLOW BRECCIA, FOR MORE INFORMATION
