Submarine upwelling of magma at a constructive plate margin took place at Troodos 85 M.a. B.P. forming oceanic lithosphere which proceeded to cool both by conductive heat transfer as well as by convective mass transfer of seawater. The convection of seawater through the newly fo…

Analysis of coprolites for pollen, phytoliths, macrofossil remains (both floral and faunal), and parasites provides the basis for identifying elements of the diet. Forty-nine coprolites represent juveniles and adults from two cemeteries at Kulubnarti. The cemetery on the island …

The carbonate encrusting process and its consequent products (crusts, tufa and travertine) in the southern Morocco (Ouarzazate) are studied in this thesis. A detailed inventory of the carbonate deposits is given. The dynamic aspects of carbonate precipitation and dissolution are…

Quaternary climates of the Middle East were investigated by reevaluating previous data and by analyzing pollen in radiocarbon-dated sediments. For comparison, assemblages of modern pollen were obtained from desert regions. Chenopodiaceae and Plantago pollen is high in surface sa…

Pollen studies of archaeological sites in South Asia are still in their infancy, and palaeobotanical information for the Indus Civilization is generally poor. Despite the lack of palaeoenvironmental studies, theories concerning climatic change during the Harappan period are prev…

This dissertation reviews the Cretaceous-Cenozoic record of ferns in Africa and assesses the paleoenvironmental significance of selected taxa from Cenozoic deposits from Ethiopia. In particular, plant macrofossils, including ferns and angiosperms, and sediments from a Late Oligo…

As part of the ongoing Harvard-Cornell Archaeological Exploration of Sardis, research directed at providing information about environmental change in central Lydia was undertaken. As part of that research, a 12 meter long sediment core was obtained from Golcuk (elevation 1050 m)…

The Faraghan Formation, a thick sequence of Upper Paleozoic strata of southern Iran, was studied palynologically to establish the palynofloras and determine more precisely the geological age of the Formation, and make logical interpretations of the depositional sites in order to…
