DSDP Major-Element Chemical Analyses 12/86 ================================================= = DEEP SEA DRILLING PROJECT = = MAJOR-ELEMENT CHEMICAL ANALYSES = = IGNEOUS AND METAMORPHIC ROCKS DATA FILE = ================================================= I. INTRODUCTION A. BACKGROUND The file contains major-element analyses of igneous and metamorphic rocks and of a few sedimentary rocks composed of volcanic material. A separate file contains minor and trace-element analyses. Data were encoded primarily from the "Initial Reports", although authors' manuscripts or the shipboard "Hole Summary Book" also were sources. The file contains both shipboard analyses and analyses from onshore laboratories. Shipboard analyses, using x-ray fluorescence methods, were made during DSDP Legs 37, 45, 46, 51-55, 61, 65, 68, 69, 82 and 83. B. METHODS Data for the elements Si, Al, Fe, Mg, Ca, Na, K, Ti, Mn, P, S, the volatiles, and the magnesium number are stored in a fixed field format. The element concentrations are given in oxide weight percent, except for sulfur which may be listed either as an element weight percent or as the oxide SO3 Major element concentrations given in the source in ppm were converted to oxide weight percent by the DSDP encoders for this data file. All records are in the same format. Each record is 292 characters long and represents a single chemical analysis of a sample. The analyses are not necessarily complete for each sample. Each record includes an identifying code for the analyst's or the first author's name. See Table 1 for the index to analysts' codes. Each record has a code indicating whether the rock is igneous, sedimentary or metamorphic. Up to three analytical methods used in the determinations may be identified, e.g., x-ray fluorescence (XF), atomic absorption (AA). Lithological information about the rock sample, including the rock name and a visual estimate of the degree of alteration, is taken from the Visual Core Descriptions for Igneous Rocks forms, which are completed by the shipboard scientists soon after core recovery. The sample number assigned to the rock is included when available. Fifteen columns are reserved for analytical information codes, such as whether the Fe oxide partitioning has been done by analysis or by calculation for a given Fe+++/Fe++ or whether or not the analysis was done onboard ship, or if the total water is directly determined. Blank fields mean not determined. 0.00 means not detected. A "-" preceding a concentration means "less than". However, a "-" preceding the LOI (Loss on Ignition) means weight was taken up during the heating of the sample. C. LEGS IN DATA SET The data set contains data from Legs 12-19, 22-30, 32-39, 41-43, 45-46, 49, 51-55, 57-70, 72-76, 78-84, 86, 89, 91-92. D.

FIELD DESCRIPTIONS AND CODES 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 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. SAMPLE MIDPOINT DEPTH: The subbottom depth in meters to the level at which the core was sampled.

ALTERATION: TABLE 3 - ALTERATION CODES F = Fresh S = Slightly altered M = Moderately altered E = Extensively altered T = Almost totally altered This information is obtained from the alteration column on the Visual Core Description - Igneous Rocks form. If alteration information is not given in the alteration column, the text of the Visual Core Description is scanned for information on alteration. Frequently there is no reliable alteration information. ROCK TYPE: TABLE 4 - ROCK TYPE CODES I = Igneous S = Sedimentary M = Metamorphic ROCK NAME: Lithological information about the rock sample, including the rock name and a visual estimate of the degree of alteration is taken from the Visual Core Description for Igneous Rocks forms, which are completed by the shipboard scientists soon after core recovery. The rock names are based on the mineralogy of the visible minerals in hand specimens and on texture. Occasionally the rock was described as grading from one type rock to another. In this case, the rock name is a range, for example, "aphyric to plag sparsely phyric basalt". FE2O3(TOTAL), FEO(TOTAL), FE2O3, FEO: In any sample the iron (Fe) exists in combination with oxygen both as Fe2O3 and FeO. When the total amount of iron in the sample is determined, it is a convention often to express it either as Fe2O3 (total) or FeO (total). Fe2O3 (total) is stored in columns 109-114. FeO (total) is stored in columns 115-120. All shipboard analyses for Fe are expressed as Fe2O3. The analyzed for Fe oxide values Fe2O3 and FeO are stored in columns 121-126 and 127-132 respectively. When the partitioning has been done by calculation, i.e., when the analyst assumes a given percentage of the total Fe oxide in the sample is Fe2O3 with the remainder FeO, column 9 in the analytical information codes is set to true(1). LOSS ON IGNITION (LOI): LOI's given in the source as "LOI at 110o and 1050o were encoded in the H2O- and H2O+ fields respectively. The analytical information code 5 was set to true(1). A "-" preceding the LOI means weight was taken up during the heating of the sample. H2O+: H2O+ is the bound water driven off when the sample is heated in an oven at 1050o C. If only "total water" was given in the source, it was entered in the H2O+ field. Analytical information code 3 was set to false(2) and analytical information code 4 was set to true (1). H2O-: H2O- is the amount of water on the grains of the sample driven off when the sample is heated in an oven overnight at 110o C. MAGNESIUM NUMBER: The magnesium number is the atomic ratio Mg/(Mg + Fe), where Fe is total iron. For some analyses the analyst has either measured or calculated Fe++. The magnesium number for these analyses is derived from Mg/(Mg + Fe++). Analytical information code 15 is set to true(1) for the Mg++ number and set to false(2) for the Mg number where Fe is total iron. ANALYTICAL INFORMATION: TABLE 5 - ANALYTICAL INFORMATION CODES Col 223: Analysis normalized to 100% in source. Col 224: Analyses in table are on a volatile-free basis (e.g., samples analyzed after ignition or analyses recalculated to 100% without the volatiles.) Col 225: Total water not directly determined.
