  1. 1. Stratigraphy and palaeoenvironment of the early Jurassic volcaniclastic strata at Djupadalsmölla, central Skåne, Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Per Wahlquist; [2023]
    Keywords : volcaniclastic; Djupadalsmölla; CSVP; palynomorphs; early Jurassic; late Pliensbachian; Earth and Environmental Sciences;

    Abstract : From the almost 200 volcanic outcrops in the Central Skåne Volcanic Province (CSVP), only three are of volcaniclastic material. These volcanoclastics, and the transition to the underlying crystalline basement, have been investigated for the first time in a drill core (KBH2) from Djupadalsmölla in order to understand the stra-tigraphy, depositional process, age of deposition, and depositional environment.

  3. 2. Archaeological dental calculus reveals patterns of dietary shifts related to the farming transition in Africa

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Ivany Jocelyne Argueta Mejia; [2023]
    Keywords : dental calculus; ancient DNA; oral microbiome; shotgun sequencing; biofilm; metagenomics;

    Abstract : Archaeological dental calculus represents a depositional environment that entraps oral microbes, and debris of dietary, environmental, and cultural material that entered the mouth throughout the host’s life. Hence, they represent valuable archives of information about the host’s lifestyle, health, and environment. READ MORE

  4. 3. Reconstructing Mid-Late Holocene Arctic Climate Using Loess Deposits From Kangerlussuaq, Greenland

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : William Mörtsjö Zung; [2023]
    Keywords : ;

    Abstract : The current geological epoch, the Holocene, began 11,700 years ago. During this time, a thermal maximum in temperature was reached somewhere during the early-middle stage at 8-5 kyrs ago which was followed by a period of neoglacial cooling, culminating in the little ice age (LIA).

  5. 4. Grain Size Analysis of Late Pleistocene Loess Deposits, Jersey

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Joakim Edlund; [2022]
    Keywords : Jersey; loess; grain size; ice age; past climate; Jersey; löss; kornstorlek; istid; forntida klimat;

    Abstract : As the world faces the effects of rapid climate change it is essential that we understand how the Earth’s climate has evolved in recent geological history. The island of Jersey harbours loess deposits which hold clues to recent climate change which have not been extensively studied. READ MORE

  6. 5. Late Quaternary Climate Reconstruction Using Rock - Magnetism in Loess on Portelet, Jersey

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Elias Hero; [2022]
    Keywords : ;

    Abstract : Loess is a very fine aeolian sediment that can be used as a proxy for stadial and interstadial glacialperiods. To understand how Earth’s climate have changed and what effects that change have had on theplanet and life on it we can use climate archives. READ MORE
