Palaeoenvironmental variabilities: A multi-proxy study of lacustrine sediments from salt lakes in the Antequera region (Andalusia), Southern Spain

Within the framework of the work of the Collaborative Research Centre 806 which investigates the history of the humankind, a multi-proxy analysis was applied on lacustrine sediments of Andalusia, Southern Spain. In this study different methods were applied on the sediments of the Laguna Dulce, Laguna Salada, Laguna de la Ratosa and the Laguna del Gosque to gain valuable information about past climate and environment, like the magnetic susceptibility, the X-ray fluorescence method and pollen analysis. Salt...

Lakustrine Sedimente der Laguna de Fuente de Piedra: Ein Vergleich von zwei RFA-Messgeräten mittels statistischer Parameter

The geochemical element analysis is an important part of the examination of lacustrine sediments for paleoclimatic reconstructions. X-ray fluorescence analysis is thereby one of the most important methods. Generally, stationary measuring devices are used, but nowadays cost-effective, portable instruments are used more and more. Subject of this work is the comparison of the high-resolution stationary ITRAX core scanner with the portable, allterrain Niton XLt 700 series environmental analyzer. Lake sediments...

Laguna Hondilla und Laguna de la Paja (Südspanien): Eine Paläoklimatische Betrachtung mittels multi-proxy Untersuchung

The Collaborative Research Centre 806 established by the universities of Cologne, Bonn and Aachen reconstructs climatic conditions on the Iberian Peninsula in the quaternary. Lake sediments are especially useful for these reconstructions because of their high-resolution, interruption-free record of the palaeoenvironment. This thesis therefore examines the lithological and geochemical composition of lake sediments from Laguna Hondilla and Laguna de la Paja, including sedimentological analysis as well as...

Endorheische Becken in SW-Spanien: eine GIS-Vorerkundung zu weiterführenden Paläoumwelt-Studien Spatial

To understand paleoenvironment and its evolution, paleoenvironmental reconstruction is indispensable. Various climate archives containing data of several thousands of years allow conclusions about environmental conditions in prehistoric times. On the Iberian Peninsula such significant data can be found in lacustrine depositions in endorheic salt lakes. The Collaborative Research Centre 806 (CRC 806) established by the universities of Cologne, Bonn and Aachen examines the history and migration of humanity...

Sedimentologische und geochemische Studie an Ablagerungen im Einzugsgebiet der „Laguna de Medina“; Südspanien

The Laguna de Medina is a semi-permanent shallow inland lake in Andalucía, South Spain. It is an ideal climate record so it is under paleolimnical investigation by the Collaborative Research Centre 806, which is investigating the way of mankind from Africa to Europe. Therefore, it was necessary to check the official geological map of the region in order to adjust it if it is necessary. Therefor were taken soil samples around the lake. Following that, the samples were examined in view of sedimentological und...

Umweltgeschichte der Laguna de Medina, Südspanien – ein geochemischer Ansatz

Diese Arbeit behandelt einen 26 m langen Sedimentkern aus der Laguna de Medina, ein See in Cádiz, der südlichsten Provinz Spaniens. Die Bohrkampagne fand im Rahmen des SFB 806 „Our way to Europe“ im März 2015 statt. Zielsetzung der Arbeit ist die Identifikation und Interpretation von Veränderungen in der Umweltgeschichte des Sees mit Hilfe geochemischer Methoden. So wurden Kohlenstoff-, Stickstoff- und Schwefel-Gehalte (C, N, S) mit dem „vario microtube“ der Firma Elementar bestimmt, während der „Dimatoc...

Korngrößenverteilung in der Sedimentabfolge der Laguna de Medina, Südspanien

Bei der Untersuchung von Proben des Sedimentbohrkerns CO1313 (N 36°37’04,380; W 06°03’12,720) aus der Laguna de Medina im Südwesten Spaniens wurde die Korngrößenverteilung ermittelt, um Aussagen über den klimatisch gesteuerten Eintrag der Sedimente zu treffen. Die Sedimentsequenz liefert eine kontinuierliche Abfolge von siltigen Tonen. Die enthaltenen feinen Sande wurden vermutlich durch äolische Einträge aus der Sahara geliefert und traten während kalter und arider Bedingungen mit verstärkten Winden aus...

Mikropaläontologische Untersuchung an den Sedimenten der Laguna Salada (Spanien)

Nowadays it is taken as demonstrated, that Modern Man developed in Africa and then spread throughout western Eurasia. But what induced the humans to leave their homeland and which routes they used to get to Eurasia is nowhere near to be sufficiently investigated. There is a good case to believe that the humans were forced to resettle by extraneous circumstances, such as drastic climatic changes. To answer the question of their motives and their migratory route in a satisfactory manner, "climatic archives"...
