    Many coastal and estuarine environments are dominated by mixtures of non-cohesive sand and cohesive mud. The migration rate of bedforms, such as ripples and dunes, in these environments is important in determining bed ...
  • Biomass recycling and Earth's early phosphorus cycle 

    Kipp, Michael; Stueeken, Eva Elisabeth (2017-11-22) - Journal article

  • Boron isotopes in foraminifera : systematics, biomineralisation, and CO2 reconstruction 

    Rae, James W. B. (Springer, 2018) - Book item
    The boron isotope composition of foraminifera provides a powerful tracer for CO2 change over geological time. This proxy is based on the equilibrium of boron and its isotopes in seawater, which is a function of pH. However ...

  • Chemical controls on incipient Mg-silicate crystallisation at 25oC : implications for early and late diagenesis 

    Tosca, Nick; Masterson, Andrew (2014-04) - Journal article
    Mg-silicate minerals (e.g., stevensite, kerolite, talc, sepiolite) play an important role in the construction of facies models in lacustrine and peri-marine environments because they are sensitive to changes in solution ...

    Swindles, Graeme T.; Watson, Elizabeth J.; Savov, Ivan P.; Lawson, Ian T.; Schmidt, Anja; Hooper, Andrew; Cooper, Claire L.; Connor, Charles B.; Gloor, Manuel; Carrivick, Jonathan L. (2018-01) - Journal article
    Human-induced climate change is causing rapid melting of ice in many volcanically active regions. Over glacial-interglacial time scales changes in surface loading exerted by large variations in glacier size affect the rates ...
  • Continental growth seen through the sedimentary record 

    Dhuime, Bruno; Hawkesworth, Chris J.; Delavault, Hélène; Cawood, Peter A. (2017-07-15) - Journal article
    Sedimentary rocks and detrital minerals sample large areas of the continental crust, and they are increasingly seen as a reliable archive for its global evolution. This study presents two approaches to model the growth of ...
  • The continental record and the generation of continental crust 

    Cawood, Peter Anthony; Hawkesworth, Chris; Dhuime, Bruno Philippe Marcel (2013-01) - Journal article
    Continental crust is the archive of Earth history. The spatial and temporal distribution of Earth's record of rock units and events is heterogeneous; for example, ages of igneous crystallization, metamorphism, continental ...
  • Cosmogenic exposure age constraints on deglaciation and flow behaviour of a marine-based ice stream in western Scotland, 21–16 ka 

    Small, David; Benetti, Sara; Dove, Dayton; Ballantyne, Colin K.; Fabel, Derek; Clark, Chris D.; Gheorghiu, Delia M.; Newall, Jennifer; Xu, Sheng (2017-07-01) - Journal article
    Understanding how marine-based ice streams operated during episodes of deglaciation requires geochronological data that constrain both timing of deglaciation and changes in their flow behaviour, such as that from unconstrained ...
  • Counter-intuitive influence of Himalayan river morphodynamics on Indus Civilisation urban settlements 

    Singh, Ajit; Thomsen, Kristina J.; Sinha, Rajiv; Buylaert, Jan-Pieter; Carter, Andrew; Mark, Darren F.; Mason, Philippa J.; Densmore, Alexander L.; Murray, Andrew S.; Jain, Mayank; Paul, Debajyoti; Gupta, Sanjeev (2017-11-28) - Journal article
