Alignment between seafloor spreading directions and absolute plate motions through time
Williams, Simon E; Flament, Nicolas; Muller, R. DietmarPublished 2016-02-28The history of seafloor spreading in the ocean basins provides a detailed record of relative motions between Earth's tectonic plates since Pangea breakup. Determining how tectonic plates have moved relative to the Earth's ...Open AccessArticle -
Australian-Antarctic breakup and seafloor spreading: Balancing geological and geophysical constraints
Williams, Simon E; Whittaker, Joanne M; Halpin, Jacqueline A; Muller, R. DietmarPublished 2019-01-01The motion of diverging tectonic plates is typically constrained by geophysical data from preserved ocean crust. However, constraining plate motions during continental rifting and the breakup process relies on balancing ...Open AccessArticle -
Dynamic topography of passive continental margins and their hinterlands since the Cretaceous
Muller, R. Dietmar; Hassan, Rakib; Gurnis, Michael; Flament, Nicolas; Williams, Simon EPublished 2018-01-01Even though it is well accepted that the Earth's surface topography has been affected by mantle-convection induced dynamic topography, its magnitude and time-dependence remain controversial. The dynamic influence to ...Open AccessArticle -
Formation of Australian continental margin highlands driven by plate-mantle interaction
Muller, R. Dietmar; Flament, Nicolas; Matthews, Kara J; Williams, Simon E; Gurnis, MichaelPublished 2016-05-01Passive margin highlands occur on most continents on Earth and play a critical role in the cycle of weathering, erosion, and atmospheric circulation. Yet, in contrast to the well-developed understanding of collisional ...Article -
Global kinematics of tectonic plates and subduction zones since the late Paleozoic Era
Young, Alexander; Flament, Nicolas; Maloney, Kayla T.; Williams, Simon E; Matthews, Kara J; Zahirovic, Sabin; Muller, R. DietmarPublished 2019-08-15Detailed global plate motion models that provide a continuous description of plate boundaries through time are an effective tool for exploring processes both at and below the Earth's surface. A new generation of numerical ...Open AccessArticle -
Global patterns in Earth's dynamic topography since the Jurassic: The role of subducted slabs
Rubey, Michael; Brune, Sascha; Heine, Christian J; Davies, Rhodri D; Williams, Simon E; Muller, R. DietmarPublished 2017-09-11We evaluate the spatial and temporal evolution of Earth's long-wavelength surface dynamic topography since the Jurassic using a series of high-resolution global mantle convection models. These models are Earth-like in terms ...Open AccessArticle -
Global plate boundary evolution and kinematics since the late Paleozoic
Matthews, Kara J; Maloney, Kayla T; Zahirovic, Sabin; Williams, Simon E; Seton, Maria; Muller, R. DietmarPublished 2016-11-01Many aspects of deep-time Earth System models, including mantle convection, paleoclimatology, paleobiogeography and the deep Earth carbon cycle, require high-resolution plate motion models that include the evolution of the ...Open AccessArticle -
Global tectonic reconstructions with continuously deforming and evolving rigid plates
Gurnis, Michael; Yang, Ting; Cannon, John S; Turner, Mark; Williams, Simon E; Flament, Nicolas; Muller, R. DietmarPublished 2018-07-01Traditional plate reconstruction methodologies do not allow for plate deformation to be considered. Here we present software to construct and visualize global tectonic reconstructions with deforming plates within the context ...Open AccessArticle -
The GPlates Portal: Cloud-Based Interactive 3D Visualization of Global Geophysical and Geological Data in a Web Browser
Muller, R. Dietmar; Qin, Xiaodong; Sandwell, David T; Dutkiewicz, Adriana; Williams, Simon E; Flament, Nicolas; Maus, Stefan; Seton, MariaPublished 2016-03-03The pace of scientific discovery is being transformed by the availability of 'big data' and open access, open source software tools. These innovations open up new avenues for how scientists communicate and share data and ...Open AccessArticle -
Improving global paleogeography since the late Paleozoic using paleobiology
Cao, Wenchao; Zahirovic, Sabin; Flament, Nicolas; Williams, Simon E; Golonka, Jan; Muller, R. DietmarPublished 2017-12-04Paleogeographic reconstructions are important to understand Earth's tectonic evolution, past eustatic and regional sea level change, paleoclimate and ocean circulation, deep Earth resources and to constrain and interpret ...Open AccessArticle -
The interplay of dynamic topography and eustasy on continental flooding in the late Paleozoic
Cao, Wenchao; Flament, Nicolas; Zahirovic, Sabin; Williams, Simon E; Muller, R. DietmarPublished 2019-06-20Global sea level change can be inferred from sequence stratigraphic and continental flooding data. These methods reconstruct sea level from peri-cratonic and cratonic basins that are assumed to be tectonically stable and ...Open AccessArticle -
Kinematic constraints on the Rodinia to Gondwana transition
Merdith, Andrew S; Williams, Simon E; Muller, R. Dietmar; Collins, Alan SPublished 2017-09-01Earth's plate tectonic history during the breakup of the supercontinent Pangea is well constrained from the seafloor spreading record, but evolving plate configurations during older supercontinent cycles are much less well ...Open AccessArticle -
The Late Cretaceous to recent tectonic history of the Pacific Ocean basin
Wright, Nicky M; Seton, Maria; Williams, Simon E; Muller, R. DietmarPublished 2016-03-01A vast ocean basin has spanned the region between the Americas, Asia and Australasia for well over 100 Myr, represented today by the Pacific Ocean. Its evolution includes a number of plate fragmentation and plate capture ...Open AccessArticle -
Oblique rifting: The rule, not the exception
Brune, Sascha; Williams, Simon E; Muller, R. DietmarPublished 2018-10-26Movements of tectonic plates often induce oblique deformation at divergent plate boundaries. This is in striking contrast with traditional conceptual models of rifting and rifted margin formation, which often assume 2-D ...Open AccessArticle
