Received: 27 May 2018; Accepted: 30 July 2018; Published: 3 August 2018 Abstract: Zircon U–Pb dating and Hf isotopic analyses are performed on clastic rocks, sedimentary tuff of the Dongchuan Group (DCG), and a diabase, which is an intrusive body from the base of DCG in the SW Yangtze Block. The results provide new constraints on the Precambrian basement and the Late Paleoproterozoic to Mesoproterozoic tectonic evolution of the SW Yangtze Block, South China. DCG has been divided into four formations from the bottom to the top: Yinmin, Luoxue, Heishan, and Qinglongshan. The Yinmin Formation, which represents the oldest rock unit of DCG, was intruded by a diabase dyke. The oldest zircon age of the clastic rocks from the Yinmin Formation is 3654 Ma, with "Hf(t) of −3.1 and a two-stage modeled age of 4081 Ma. Another zircon exhibits an age of 2406 Ma, with "Hf(t) of −20.1 and a two-stage modeled age of 4152 Ma.

  • Plate Tectonics on Early Earth? Weighing the Paleomagnetic Evidence
    spe440-12 3rd pages The Geological Society of America Special Paper 440 2008 Plate tectonics on early Earth? Weighing the paleomagnetic evidence David A.D. Evans* Department of Geology & Geophysics, Yale University, New Haven, Connecticut 06520-8109, USA Sergei A. Pisarevsky* School of GeoSciences, University of Edinburgh, Edinburgh EH9 3JW, Scotland, UK ABSTRACT Paleomagnetism is the only quantitative method available to test for lateral motions by tectonic plates across the surface of ancient Earth. Here, we present several analyses of such motions using strict quality criteria from the global paleomagnetic database of pre–800 Ma rocks. Extensive surface motion of cratons can be documented confi dently to older than ca. 2775 Ma, but considering only the most reliable Archean data, we cannot discern differential motion from true polar wander (which can also generate surface motions relative to the geomagnetic reference frame). In order to fi nd evidence for differential motions between pairs of Precambrian cratons, we compared distances between paleomagnetic poles through precisely isochronous intervals for pairs of cra- tons. The existing database yields several such comparisons with ages ranging from ca. 1110 to ca. 2775 Ma. Only one pair of these ages, 1110–1880 Ma, brackets signifi cantly different apparent polar wander path lengths between the same two cratons and thus demonstrates differential surface motions. If slightly less reliable paleomagnetic results are considered, however, the number of comparisons increases dramatically, and an example is illustrated for which a single additional pole could constrain differential cratonic motion into the earliest Paleoproterozoic and late Neoarchean (in the interval 2445–2680 Ma).

  • 125 Paleomagnetic Study of the Mesoproterozoic
    PALEOMAGNETIC STUDY OF THE MESOPROTEROZOIC SATAKUNTA DYKE SWARM, FINLAND, WITH IMPLICATIONS FOR A NORTHERN EUROPE – NORTH AMERICA (NENA) CONNECTION WITHIN NUNA SUPERCONTINENT Johanna Salminen1, Satu Mertanen2 and David Evans3 1. Department of Physics, Division of Geophysics and Astronomy, University of Helsinki, Finland 2. Geological Survey of Finland, South Finland Unit, Espoo, Finland 3. Department of Geology and Geophysics, Yale University, New Haven, USA Paleoproterozoic supercontinent Nuna (Columbia, Hudsonland) has been suggested by several studies. Many recent reconstructions of this supercontinent are based on assumption that the core of Nuna was formed by the united Baltica and Laurentia cratons forming the NENA (Northern Europe – North America) configuration that lasted from 1.8 Ga to at least 1.26 Ga. However, recent 1.6 Ga data from Greenland appear to challenge this fit (Halls et al., 2011). Our new data from the Mesoproterozoic (1565 Ma) diabase dyke swarm in Satakunta, western Finland, provides new paleomagnetic evidence to test the NENA configuration. From the Satakunta dykes a dual-polarity, high-stability remanence component was obtained and it was confirmed to be primary by several baked contact tests. A suite of rock-magnetic analyses demonstrates that pseudo-single domain magnetite is the remanence carrier. The combined mean remanence direction for both polarities is D = 8.3°, I = 6.5° ( 95 = 5.9°), yielding a new key paleomagnetic pole for Baltica at 32.7°N, 188.7°E (A95 = 4.2°). This pole fulfills six out of seven van der Voo factors. Based on the reconstruction by using the new Satakunta pole and the nearly coeval (1592 Ma) Western Channel Diabase pole from Laurentia (Irving, 1972; Hamilton and Buchan, 2010), the NENA fit existed at 1.57-1.59 Ga.

D. EVANS Department of Geology & Geophysics, Yale University, New Haven, CT 06520-8109, USA (e-mail: [email protected]) Abstract: Palaeomagnetic apparent polar wander (APW) paths from the world’s cratons at 1300–700 Ma can constrain the palaeogeographic possibilities for a long-lived and all-inclusive Rodinia supercontinent. Laurentia’s APW path is the most complete and forms the basis for super- position by other cratons’ APW paths to identify possible durations of those cratons’ inclusion in Rodinia, and also to generate reconstructions that are constrained both in latitude and longitude relative to Laurentia. Baltica reconstructs adjacent to the SE margin of Greenland, in a standard and geographically ‘upright’ position, between c. 1050 and 600 Ma. Australia reconstructs adja- cent to the pre-Caspian margin of Baltica, geographically ‘inverted’ such that cratonic portions of Queensland are juxtaposed with that margin via collision at c. 1100 Ma. Arctic North America reconstructs opposite to the CONgo þ Sa˜o Francisco craton at its DAmaride–Lufilian margin (the ‘ANACONDA’ fit) throughout the interval 1235–755 Ma according to palaeomag- netic poles of those ages from both cratons, and the reconstruction was probably established during the c.

Characteristic timescales of the cycle are typically 500–700 myr. Proposed spatial patterns of cyclicity range from hemispheric (introversion) to antipodal (extroversion), to precisely between those end-members (orthoversion). Advances in our understanding can arise from theoretical or numerical modelling, primary data acquisition relevant to continental reconstructions, and spatiotemporal correlations between plate kinematics, geodynamic events and palaeoenvironmental history. The palaeogeographic record of supercontinental tectonics on Earth is still under development. The contributions in this special publication provide snap-shots in time of these investigations and indicate that Earth’s palaeogeographic record incorporates elements of all three endmember spatial patterns.

This work is licensed under the Creative Commons Attribution International License (CC BY). http://creativecommons.org/licenses/by/4.0/ Abstract The Amazonian craton major accretionary and collisional processes may be correlated to super- continent assemblies developed at several times in the Earth history. Based on geologic, structural and paleomagnetic evidence paleocontinent reconstructions have been proposed for Archean to younger times. The oldest continent (Ur) was formed probably by five Achaean cratonic areas (Kaapvaal, Western Dhawar, Bhandara, Singhhum and Pilbara cratons). Geologic evidences sug- gest the participation of the Archaean rocks of the Carajás region in the Ur landmass. Superconti- nental 2.45 Ga Kenorland amalgamation is indicated by paleomagnetic data including Laurentia, Baltica, Australia, and Kalahari and Kaapvaal cratons. There is no evidence indicating that Amazo- nian craton was part of the Kenorland supercontinent. From 1.83 Ga to 1.25 Ga Columbia and Hudsonland supercontinents including Amazonian craton were proposed based on NE portion of the Amazonian craton (Maroni/Itacaiunas province) connection with West Africa and Kalahari cratons.

In addition to qualitative 30 September 2014 correlations of orogenic belts, rift basin ages, stratigraphy and distribution of igneous provinces, paleo- Accepted 3 October 2014 magnetic data can provide key constraints on the positioning of individual cratons on the globe. In this Available online 14 October 2014 paper, we report a detailed paleomagnetic study on the coeval ∼1780 Ma mafic dyke swarm and Xiong’er volcanic province, which extended for more than one thousand kilometers in the central NCC.
