DSDP Minor-Element Chemical Analyses 12/86 ================================================= = DEEP SEA DRILLING PROJECT = = MINOR AND TRACE-ELEMENT CHEMICAL ANALYSES = = IGNEOUS AND METAMORPHIC ROCKS DATA FILE = ================================================= I. INTRODUCTION A. BACKGROUND The file contains minor and trace-element analyses of igneous and metamorphic rocks and of a few sedimentary rocks composed of volcanic material. 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. The shipboard minor-element determinations were for Ni, Sr, Zr, and Cr only. B. METHODS Concentrations and other information about fifty-five elements are stored in a fixed-field format. The element concentrations are given in parts per million (ppm). Minor-element concentrations given in the source in oxide weight percent were converted to parts per million by the DSDP encoders for this file. All records are in the same format. Each record is 590 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. This file does not specify whether the analysis was performed onboard ship or at a shore facility. However, the sample number and the analyst's code can be used to find additional information either in the data source or the DSDP Major-Element Chemical Analyses file. Blank fields mean not determined. 0.00 means not detected. A "-" preceding a concentration means "less than". C. LEGS IN DATA SET The data set contains data from Legs 12-19, 22-26, 28-30, 32-34, 36-39, 41-43, 45-46, 49, 51-55, 58-70, 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.

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".
