Sect:  1    Top of Section Depth(m):   141.14

LITHOLOGY: BASALT;

  Piece No.  : PCE NO PCE NUMBERS ASSIGNED;

  Texture    : VERY FINE-GRAINED (APHANITIC), WITH GLASSY BASALT,
               GLASS HAS RED OBSIDIAN (CONTAMINATED BY HEMATITE);

  Structure  : CALCITE VEIN (APPEARS TO BE MARBLE BUT RECOGNIZABLE
               AS VEIN FILLING BECAUSE OF ITS NEARLY VERTICAL
               ORIENTATION);

               WITH CHIPS OF WHITE CHALK, FRIABLE;

  Vesicles   : SOME VESICLES AND AMYGDULES;

  Replacement: CALCITE
               CALCITE VEIN, APPEARS TO BE MARBLE;

               HEMATITE
               CONTAMINATING OBSIDIAN;
