Abstract

The present study has been undertaken to determine the nature and the factors controlling the distribution of carbonate content in Kuwait Bay sediments. The carbonate content that may be deposited with Kuwait Bay sediments is attributed to the interplay of the deposits fallout from the dust storms over Kuwaiti territory, the deposits carried in suspension by the currents from Shatt Al-Arab area and to the skeletal parts of microorganisms that may be originated in the sediments. The carbonate content increases in the coarse sediments rather than in the fine sediments. The mineral components of the carbonate present are in the form of calcite, aragonite and some dolomite. Therefore, the texture of the sediments, the rate of deposition in addition to the biological interference may exert a considerable control over carbonate distribution.

Zusammenfassung

Die Faktoren, die die Verteilung des Karbonates in den Sedimenten der Kuwait Bay bestimmen, sind
  1. 1.

    die Sedimentzufuhr über windgetragenen Staub

     
  2. 2.

    die Suspensionsfracht der Strömungen aus dem Schatt Al-Arab

     
  3. 3.

    die biogene Produktion durch Mikroorganismen.

     

Der Karbonatgehalt nimmt in den grobkörnigen Sedimenten zu. Es läßt sich Kalzit, Aragonit und etwas Dolomit nachweisen. Die Karbonatverteilung wird von der Sedimentationsrate und den biogenen Prozessen bestimmt.

Résumé

Cette note présente les résultats des études dont le but est de déterminer les facteurs affectant une répartition du carbonate dans les sédiments de la Baie de Koweit. Il y a trois sources de carbonate: la poussière éolienne, des matériaux en suspension apportés par le Shatt-Al-Arab et le carbonate biogénique déposé en forme de squelettes organiques. Il y a une corrélation positive entre la granulométrie et la teneur en carbonate des dépôts. Le carbonate contient les minéraux suivants: calcite, aragonite et des traces de dolomite.

La teneur en carbonate et sa répartition sont affectées par la granulométrie, la vitesse de sédimentation et la production organique.

Краткое содержание

Настоящее исследова ние посвящено устано влению происхождения извес тняковых осадочных пород Кува йтского залива и проц ессам, управляющим их распр еделением в заливе. Карбонаты, отлегающи еся в осадочных пород ах Кувайтского залива, с тоят в тесной связи со взвесями, вып адающими из мути речн ых потоковна территори и Кувайта, впадающих с залив, с осадками, при носимыми в виде суспе нзий потоками рек из район а Шат аль-Араб и остатками с келета микроорганиз мов, живущих в осадочных породах. С одержание карбонатов выше в гру боосколочных осадка х: Известняковые пород ы состоят из кальцита, арагонита и, порой, доломита. Поэто му текстура осадков и ск орость их отложения могут в значительной степени влиять на рас пределение карбонатов, наряду с б иологическими факторами.
