Two Contrasting Phanerozoic Orogenic Systems Revealed by Hafnium Isotope Data William J
ARTICLES PUBLISHED ONLINE: 17 APRIL 2011 | DOI: 10.1038/NGEO1127 Two contrasting Phanerozoic orogenic systems revealed by hafnium isotope data William J. Collins1*(, Elena A. Belousova2, Anthony I. S. Kemp1 and J. Brendan Murphy3 Two fundamentally different orogenic systems have existed on Earth throughout the Phanerozoic. Circum-Pacific accretionary orogens are the external orogenic system formed around the Pacific rim, where oceanic lithosphere semicontinuously subducts beneath continental lithosphere. In contrast, the internal orogenic system is found in Europe and Asia as the collage of collisional mountain belts, formed during the collision between continental crustal fragments. External orogenic systems form at the boundary of large underlying mantle convection cells, whereas internal orogens form within one supercell. Here we present a compilation of hafnium isotope data from zircon minerals collected from orogens worldwide. We find that the range of hafnium isotope signatures for the external orogenic system narrows and trends towards more radiogenic compositions since 550 Myr ago. By contrast, the range of signatures from the internal orogenic system broadens since 550 Myr ago. We suggest that for the external system, the lower crust and lithospheric mantle beneath the overriding continent is removed during subduction and replaced by newly formed crust, which generates the radiogenic hafnium signature when remelted. For the internal orogenic system, the lower crust and lithospheric mantle is instead eventually replaced by more continental lithosphere from a collided continental fragment. Our suggested model provides a simple basis for unravelling the global geodynamic evolution of the ancient Earth. resent-day orogens of contrasting character can be reduced to which probably began by the Early Ordovician12, and the Early two types on Earth, dominantly accretionary or dominantly Paleozoic accretionary orogens in the easternmost Altaids of Pcollisional, because only the latter are associated with Wilson Asia13. -

Proterozoic East Gondwana: Supercontinent Assembly and Breakup Geological Society Special Publications Society Book Editors R. J. PANKHURST (CHIEF EDITOR) P. DOYLE E J. GREGORY J. S. GRIFFITHS A. J. HARTLEY R. E. HOLDSWORTH A. C. MORTON N. S. ROBINS M. S. STOKER J. P. TURNER Special Publication reviewing procedures The Society makes every effort to ensure that the scientific and production quality of its books matches that of its journals. Since 1997, all book proposals have been refereed by specialist reviewers as well as by the Society's Books Editorial Committee. If the referees identify weaknesses in the proposal, these must be addressed before the proposal is accepted. Once the book is accepted, the Society has a team of Book Editors (listed above) who ensure that the volume editors follow strict guidelines on refereeing and quality control. We insist that individual papers can only be accepted after satis- factory review by two independent referees. The questions on the review forms are similar to those for Journal of the Geological Society. The referees' forms and comments must be available to the Society's Book Editors on request. Although many of the books result from meetings, the editors are expected to commission papers that were not pre- sented at the meeting to ensure that the book provides a balanced coverage of the subject. Being accepted for presentation at the meeting does not guarantee inclusion in the book. Geological Society Special Publications are included in the ISI Science Citation Index, but they do not have an impact factor, the latter being applicable only to journals. -
Plate Tectonics Earthquakes in Christchurch and Northern Japan in 2011 and the Haiti Earthquake in 2010 Caused Massive Destruction and Loss of Life
PROOFS 5 PAGE PLATE TECTONICS Earthquakes in Christchurch and northern Japan in 2011 and the Haiti earthquake in 2010 caused massive destruction and loss of life. What caused these and other earthquakes and volcanic eruptionsUNCORRECTED in the Earth’s history? From space, the Earth looks very peaceful, but movements of the Earth’s surface can cause huge changes. Did you know that the highest place on the Earth, Mount Everest, was once under the sea? It has been pushed up by movements of the Earth’s surface. Similar fossil specimens and rock types have been found on opposite sides of vast oceans. How can this be explained? TECTONIC PLATES 5.1 Looking at a map of the world it is easy to see why people started wondering if the continents once fitted together like a giant jigsaw puzzle. The distribution of some plants and animals and even fossil species cannot be explained unless the continents had drifted apart over time. These continents have slowly moved across the face of the planet, separating and potentially isolating populations. Whilst these organisms have adapted to their new unique environmental conditions, the rocks that were formed when the continents were joined have remained the same. Students: » •outline how the theory of plate tectonics changed ideas about the structure of and changes in the Earth’s surface » •relate continental drift to convectionPROOFS currents and gravitational forces ACTIVITY AT PLAPAGETE BOUN DARIES 5.2 As the huge tectonic plates move across the surface of the Earth, they collide, grind past one another or slowly pull away from each other. -

The map looks at how the world would be completely different if the South Atlantic and West African rift had split, instead of the rift that emerged along the Equatorial Atlantic margins. Geoscientists at the University of Sydney and the GFZ German Research Centre for Geosciences used sophisticated plate tectonic and 2D numerical modelling to create the map. The Gondwana supercontinent broke up 130 million years ago leading to the creation of South America and Africa. However, for millions of years before this, the southern continents of Why advertise with us South America, Africa, Antarctica, Australia, and India were united as Gondwana. READ MORE It is still unclear why Gondwana fragmented, but it is understood if first split along the East Africa coast in a western and eastern part, before South America separated.
