The structure and dynamics of the lithosphere beneath Tibet from seismic surface-wave analysis
(Trinity College (Dublin, Ireland). Department of Geology, 2013)Despite the numerous studies undertaken to investigate the underlying structures beneath the Tibetan Plateau, fundamental questions about the mechanism of lithospheric convergence between India and Asia (establishing if ... -
Nitrogen isotopes in the palynomorph Tasmanites, as an indicator of climate change
(Trinity College (Dublin, Ireland). Department of Geology, 2014)The stable nitrogen isotope signature (δ15N) of plants and animals preserved in sedimentary rocks retain a record of past oceanic and atmospheric chemical changes. The majority of modem nitrogen isotope studies focus ... -
Thermal modelling of planetesimals heated by 26 A1 : implications for chondrule formation
(Trinity College (Dublin, Ireland). Department of Geology, 2002)Chondrules are enigmatic components of chondritic meteorites. After decades of research a consensus as to how chondrules formed has not been found. In general it has been assumed that chondrules formed in the solar nebula ... -
Phosphorus exports from agricultural grassland in overland flow and subsurface drainage water
(Trinity College (Dublin, Ireland). Department of Geology, 2003)On the background of increasing phosphorus (P) concentrations in Irish rivers and lakes, this project set out to investigate several aspects of the potential of agricultural grassland to lose P to water. All study sites ... -
The genesis of exceptionally thick shallow marine sequences exposed within the South Munster Basin of southern Ireland
(Trinity College (Dublin, Ireland). Department of Geology, 2002)The South Munster Basin (southern Ireland) is an E-W trending fossil rift system that was active during the Late Devonian and Early Carboniferous. Subsidence during this period was rapid and led, despite a high sediment ...
