 I.  INTRODUCTION 
                                                                 

 A.  BACKGROUND 
                                                                 

     This file contains encoded megascopic descriptions of drill
     core sections of igneous and metamorphic rocks and a few
     core sections containing sedimentary rocks composed of
     volcanic material.  The vast majority of the descriptions
     were encoded from shipboard Visual Core Descriptions -
     Igneous Rocks forms.  Some descriptions were encoded from
     the "Initial Reports of the Deep Sea Drilling Project".

 B.  METHODS 


     The descriptions were encoded with a minimum of editing
     unless there were instructions to edit from the shipboard
     petrographer or the DSDP staff representative.  No summaries
     of visual core descriptions, only descriptions of individual
     core sections, were encoded.

     A 12x binocular microscope was used in the shipboard hand
     sample studies.

     An attempt was made to be consistent in terminology and in
     organization of the data.  See Table 2 for special
     abbreviations used in this file.

     A code for the describer's name, when available, was
     included with each description.  See Table 1 for the index
     to describers' codes.

     Each core section description can be organized into ten
     categories of information.  The categories are represented
     by codes.  Each data record begins in column 1 with the
     appropriate code.  The codes are:

          Rock name (L)
          Piece number (N)
          Structure (S)
          Vesicles (V)
          Texture (T)
          Phenocrysts (P)
          Groundmass (G)
          Alteration, or Replacement, minerals (R)
          Alteration, degree of (A)
          Other information (O)

     The data records are organized into both narrative and
     fixed-field formats.  Six of the codes are exclusively
     associated with narrative data.  These are Rock name (L),
     Piece number (N), Structure (S), Texture (T), Degree of
     alteration (A), and Other information (O).  Four codes have
     both narrative and fixed-field data.  They are Vesicles (V),
     Phenocryts (P), Groundmass minerals (G), and Alteration
     minerals (R).

     Each visual core description set includes a lead record
     followed by the data records.  A minimum of one data record
     is present and it must be an (L) code record containing the
     rock name.

 C.  LEGS IN DATA SET 


     The data set contains data from legs 2-9, 11-39, 41-43,
     45-46, 49, 51-55, 57-86, 88-89, 91-92, and 94.

    The definition of leg, site, hole, core and section may be
    found in the explanatory notes.  In addition, the special
    core designations, as well as the methods of sample labeling
    and calculating absolute sample depths are discussed.



  INTERVAL DEPTH: 


      Refers to the depth in centimeters within the section at
      which the rock was sampled.  Values are encoded with an
      implicit decimal point.


  TOP OF CORE DEPTH: 


      The subbottom depth in meters to the top of the core.


  TOP OF SECTION DEPTH: 


      The subbottom depth in meters to the top of the section
      being described.


  SAMPLE MIDPOINT DEPTH: 

      The subbottom depth in meters to the level at which the
      core was sampled.


  DESCRIBER CODE: 


    The following codes are common to the DSDP igneous and
    metamorphic rocks data bases.

  NUMBER OF PHYSICAL RECORDS: 


      The total number of physical records which together
      comprise a complete visual core description.  Since there
      is always a lead record and at least one data record, the
      number of records is never less than two.


  PHYSICAL RECORD NUMBER: 


      Each physical record in a visual core description set is
      numbered sequentially in column 58-60.  The physical record
      number will always be "1" for the lead record.


  VISUAL CORE DESCRIPTION DATA: 


           TABLE 3 - ABBREVIATIONS USED IN DATA RECORDS

      The following abbreviations are used in the igneous rocks
      data bases.  Other abbreviations were borrowed from the
      soft rocks data bases.  For a key to these abbreviations
      consult the documentation for the soft rocks lithological
      data bases.
