29. CHEMICAL ANALYSES OF RED SEA SEDIMENTS
Frank T. Manheim, U. S. Geological Survey, Woods Hole, MassachusettsDavid E. Siems, U. S. Geological Survey, Denver, Colorado
One of the prime motives for exploring the deepersubsurface sediments of the Red Sea floor was to gaininformation on the geochemical systems controlling the hotbrine-metalliferous deposits. Accordingly, a strong effortwas made to provide both shipboard and laboratory meansof analysis of the recovered phases. Shipboard spectro-graphic analyses (semiquantitative) provided both detailedsurveys of chemical properties of the cores and the abilityto analyze small subsamples and separated particles such aspyrite, sphalerite, organisms, and similar minute objects.Over 5000 such analyses are provided in Tables 1 to 5.Some supplementary data provided by subsequent analysesfor K, Zn, and Ag in the Denver field laboratories of theU. S. Geological Survey have been added to the tables.
A second body of data is provided in Table 6, whichgives quantitative data on major and minor constituents,performed by the Washington analytical laboratories of theU. S. Geological Survey. A third group of analyses arepartial analyses on evaporitic rocks (anhydrite and rocksalt) (Table 18, in Manheim Chapter 38, this volume).
In addition to the above, a number of the collaboratinglaboratories are providing more specific chemical data onspecial phases and constituents of the Red Sea materials.Most of these data are included in chapters in theGeochemical section of this volume.The significance of the data is discussed in Manheim (Chap-ter 38, this volume) and in the respective reports of ship-board workers and cooperating share laboratories.
