And Neoarchean Tectonic Evolution of the Northwestern Meso – and Neoarchean tectonic evolution of the northwestern Superior Province: Insights from a U-Pb geochronology, Nd isotope, and geochemistry study of the Island Lake greenstone belt, Northeastern Manitoba by Jennifer E. Parks A thesis presented to the University of Waterloo in fulfillment of the thesis requirement for the degree of Doctor of Philosophy in Earth Sciences Waterloo, Ontario, Canada, 2011 ©Jennifer E. Parks 2011 Author’s Declaration I hereby declare that I am the sole author of this thesis. This is a true copy of the thesis, including any required final revisions, as accepted by my examiners. I understand that my thesis may be made electronically available to the public. ii Abstract What tectonic processes were operating in the Archean, and whether they were similar to the “modern-style” plate tectonics seen operating today, is a fundamental question about Archean geology. The Superior Province is the largest piece of preserved Archean crust on Earth. As such it provides an excellent opportunity to study Archean tectonic processes. Much work has been completed in the southern part of the Superior Province. A well-documented series of discrete, southward younging orogenies related to a series of northward dipping subduction zones, has been proposed for amalgamating this part of the Superior Province. The tectonic evolution in the northwestern Superior Province is much less constrained, and it is unclear if it is related to the series of subduction zones in the southern part of the Superior Province, or if it is related to an entirely different process. Such ideas need to be tested in order to develop a concise model for the Meso – and Neoarchean tectonic evolution of the northwestern Superior Province. To this end, a field mapping, U-Pb geochronology, Nd isotope, and lithogeochemistry study was undertaken in the Island Lake greenstone belt. This granite-greenstone belt is part of the northern margin of the North Caribou terrane, a larger reworked Mesoarchean crustal block located in the northwestern Superior Province. U-Pb TIMS zircon geochronology data shows that the Island Lake greenstone belt experienced a long and complex geological history that included the deposition of three distinct volcanic assemblages at ca. 2897 Ma, 2852 Ma, and 2744 Ma, as well as a younger clastic sedimentary group, the Island Lake group. All of these volcanic assemblages include felsic and mafic volcanic rocks, as well as a suite of contemporaneous plutonic rocks. The U-Pb data set shows that the Savage Island shear zone, a regional fault structure that transects the Island Lake greenstone belt, is not a terrane-bounding feature as correlative supracrustal assemblages are observed on both sides of it. The Nd isotope data shows that the volcanic assemblages and contemporaneous plutons iii have been variably contaminated by an older ca. 3.0 Ga crustal source. The mafic volcanic rocks in the assemblages have two distinct geochemical signatures, and show a pattern of decreasing crustal contamination with decreasing age. Together these data suggests that the Meso – and Neoarchean volcanic assemblages are part of an intact primary volcanic stratigraphy that were built on the same ca. 3.0 Ga basement and have autochthonous relationships with each other. This basement is the North Caribou terrane. The youngest sedimentary group in the belt, the Island Lake group, was deposited between 2712 Ma and 2699 Ma. It consists of “Timiskaming-type” sedimentary rocks, and is the youngest clastic sedimentary package in the belt. A detailed study of detrital zircons in units from the stratigraphic bottom to the top of the sedimentary group indicates an age pattern of detrital zircons that is most consistent with a scenario in which sediments were deposited in inter-diapiric basins created by diapirism and sagduction (i.e., vertical tectonic) processes. During the diapiric ascent of the felsic material, inter-diapiric basins were formed in the synclines between adjacent domes, into which sediments were deposited. U-Pb zircon TIMS geochronology identified two ages of deformation in the Island Lake greenstone belt. Two dykes that crosscut an older, D1 foliation place a minimum age of ca. 2723 Ma on the D1 deformation, and two syn-kinematic dykes date movement along two transpressional shear zones to 2700 Ma. Together all these data indicate that the tectonic evolution in the Island Lake greenstone belt and in the northwestern Superior Province took place in three main stages. The first two stages involved the generation of Meso – and Neoarchean volcanic assemblages and contemporaneous plutonic rocks due to southward dipping subduction under the North Caribou micro-continent. The third stage involved the deposition of late “Timiskaming-type” sediments during vertical tectonic processes in iv conjunction with horizontal tectonic movement along late transpressional shear zones at ca. 2.70 Ga. At the end of this process the North Superior superterrane was terminally docked to the North Caribou terrane along the North Kenyon fault. This study shows that while a version of horizontal or “modern” style plate tectonics were operating in the Archean, vertical tectonic processes were also occurring and that these processes operated synchronously in the Neoarchean. v Acknowledgements I would like to thank the following organizations for financial support for this project: LITHOPROBE, NSERC and NSERC discovery grants to Shoufa Lin and Larry Heman, the Northern Scientific Training Program, the University of Waterloo, the Ontario Graduate Scholarships, and the Ontario Graduate Scholarships Science and Technology program.

This paper aims to discuss (1) when landmark events in early animal evolution occurred, and (2) the environmental context of these evolutionary milestones, and how such factors may have affected ecosystems and body plans. With respect to timing, molecular clock studies—utilizing a diversity of methodologies—agree that animal multicellularity had arisen by 800 million years ago (Ma) (Tonian period), the bilaterian body plan by 650 Ma (Cryogenian), and divergences between sister phyla occurred 560–540 Ma (late Ediacaran). Most purported Tonian and Cryogenian animal body fossils are unlikely to be correctly identified, but independent support for the presence of pre-Ediacaran animals is recorded by organic geochemical biomarkers produced by demosponges.

Juli 2010 Erscheinungsjahr: 2010 Automatic Organization of Digital Music Documents – Sheet Music and Audio Christian Fremerey Abstract This thesis presents work towards automatic organization and synchronization of scanned sheet music and digitized audio recordings in the scenario of a digital music library. The organization targeted in the project of this thesis includes the segmentation of sheet music books and audio CD collections into individual songs or movements, mapping the resulting segments to corresponding records in a database of metadata, and temporally synchronizing the sheet music documents and audio recordings that belong to the same piece of music on a bar-wise level. Building up a digital music library with a large collection of digitized sheet music and audio recordings requires automated methods for organizing the data, because a manual organization is too expensive and time-consuming. In this thesis, a complete work- flow addressing the practical issues that arise in building up and maintaining a digital music library for synchronized sheet music and audio recordings is presented. Algorithms and ap- proaches for the automatic organization of music documents are proposed and evaluated. We introduce a software application to be used by library employees for the import of new data and editing of existing records that integrates the proposed automatic methods.

  • Numbers in India's Periphery Ankush Agrawal , Vikas Kumar Frontmatter More Information
    Cambridge University Press 978-1-108-48672-9 — Numbers in India's Periphery Ankush Agrawal , Vikas Kumar Frontmatter More Information Numbers in India’s Periphery Over the past two centuries, the deep and multifaceted relation between statistics and statecraft has emerged as a defining feature of modern states across the world. Governments increasingly depend upon statistics for planning and evaluation of interventions as well as self-representation. Numbers in India’s Periphery examines systematic and deliberate errors in government statistics. Using field interviews, archival sources and secondary data, the book explores the shifting relations between various kinds of government statistics and charts their political career in Nagaland, a state located in India’s landlocked ethno-geographic periphery stretching from Mizoram to Jammu and Kashmir. This book examines the area (1951–2018), population (1951–2011) and National Sample Survey statistics (1973–2014) of Nagaland, treating them as part of a larger family of mutually constitutive statistics embedded in a shared context. It shows that Nagaland’s government statistics suffer from sustained and large errors and examines the impact of inadequacies in the data generating processes on statistics of interest to policymakers. It argues that statistics are shaped by a combination of factors, including discontent with colonial borders, competition over resource-rich territories, political unrest, competition for government spending and contests over the delimitation of administrative units and electoral constituencies in the context of weak institutions and dominance of the state in the economy. It also engages with the shared experience of other states of India, including Assam, Jammu and Kashmir and Manipur, and other countries in Africa and Asia and non-governmental statistics such as church membership data.
