  1. 1. Reconstructing Past Climate by Grain Size and Magnetic Susceptibility Analysis of Belgium Loess From the Late Quaternary

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Susanna Åberg; [2022]
    Keywords : aeolian dust; Romont; Europe; true loess line; past climate reconstruction; vindtransporterat stoft; Romont; Europa; true loess line; rekonstruktion av tidigare klimat;

    Abstract : Aeolian dust that gets deposited builds up loess sequences that cover 10% of the Earth's continents. Such sequences can be several metres thick with material deposited over thousands of years, and therefore act like archives of past climates. READ MORE

    University essay from Luleå tekniska universitet/Geovetenskap och miljöteknik

    Author : Mpho Ndebele; [2020]
    Keywords : Kimberlites; Geology; Emplacement Processes; Botswana;

    Abstract : The Crateceous (85 Ma) MK1 pipe is part of the Tsabong kimberlite cluster located approximately550km south west of Gaborone and geologically found within the Kapvaal Craton. The Tsabongkimberlite field consists of 86 known kimberlites. The MK1 pipe is the largest of this cluster at 140ha,1. READ MORE

  4. 3. Holocene lake-level changes in the Siljan Lake District – Towards validation of von Post’s drainage scenario

    University essay from Lunds universitet/Geologiska institutionen

    Author : Savvas Paradeisis-Stathis; [2020]
    Keywords : Lake Siljan; Dalarna; basin isolation; catastrophic drainage; early Holocene; lake sediments; XRF scanning; C N ratio; magnetic susceptibility; pollen; Ancylus Lake; Earth and Environmental Sciences;

    Abstract : The Dalarna province in south-central Sweden shows a great variety of geological evidence from the Late Quaternary. A peculiar deglaciation pattern, along with unique hydrological conditions, has left a lot of space for speculations over the palaeoenvironmental conditions during the early Holocene. READ MORE

  5. 4. Impact of southern Baltic sea-level changes on landscape development in the Verkeån River valley at Haväng, southern Sweden, during the early and mid Holocene

    University essay from Lunds universitet/Geologiska institutionen

    Author : Anette Nilsson Brunlid; [2018]
    Keywords : sea-level change; Littorina Sea; Baltic Sea; Ancylus Lake; environmental reconstruction; Holocene; Earth and Environmental Sciences;

    Abstract : In the Hanö bay off the coast at Haväng in SE Scania, southern Sweden, a submerged and well-preserved Mesolithic landscape is found, including remains of trees, river and lagoon sediments, and archaeological artefacts such as an antler pick axe and stationary fishing constructions. The landscape was formed during the Yoldia Sea (11,700-10,800 cal BP) and Initial Littorina Sea (9800-8500) low-water phases of the Baltic Basin. READ MORE

  6. 5. Laboratory investigation of suffusion on dam core glacial till

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Daniel Yadetie Tuffa; [2017]
    Keywords : Internal erosion; Suffusion; Filter; Core; Glacial till; Embankment dam; Hydraulic gradients;

    Abstract : The objective of this study is to provide a better understanding of suffusion characteristics of glacial soils and to present a simple yet reliable assessment procedure for determination of suffusion in the laboratory.Internal erosion by suffusion occurs in the core of an embankment dam when the ability of the soil to resist seepage forces is exceeded and voids are large enough to allow the transport of fine particles through the pores.
