Comparisons of large igneous provinces(UPs)and black shales from different cratons can provide important constraints on Precambrian paleogeographic reconstructions and a better understanding of the environmental effects of large-scale volcanic events.A comparison of intraplate mafic events mostly interpreted as LIPs or portions of LIPs(LIP fragments/remnants due to continental breakup or erosion)from the North China Craton(NCC)and North Australian Craton(NAC)shows good correlation in the age range from 1800 Ma to 1300 Ma,and four robust age matches at ca.1790-1770 Ma,ca.1730 Ma,ca.1680-1670 Ma and ca.1320 Ma have been *** notably,the coeval ca.1320 Ma Yanliao LIP in the eastern-northern NCC and the Derim Derim-Galiwinku LIP in the NAC are also characterized by similar field occurences and dominantly subalkaline tholeiitic basalts and intraplate geochemical compositions,and are interpreted as portions of the same LIP,separated by continental *** to 1300 Ma,the NCC and NAC exhibit very different magmatic histories,indicating that separation of these two cratons occurred,likely subsequent to the ca.1320 Ma LIP event.A comparison of Paleo-Mesoproterozoic black shales from the NCC and NAC provides further evidence for close connections between these regions during this *** shales of the Chuanlianggou Formation in the northern NCC and the Cuizhuang Formation in the southern NCC were deposited in the age range ca.1650-1635 Ma and can be correlated with ca.1640-1635 Ma black shales in the Barney Creek Formation of the *** of black shales within the Xiamaling Formation in the NCC and the Velkerri and Kyalla formations of the McArthur Basin in the NAC occurred synchronously at ca.1380-1360 *** results from matching of LIP ages and black shales combined with paleomagnetic data show that the northern-northeastern margin of the NCC was connected to the northern margin of the NAC from ca.1800 Ma to 1300 *** long-lived late Pal

作者： Simon M.JOWITT richard e.ernst School of earth Atmosphere and Environment Monash University Department of Geoscience University of Nevada Las Vegas Department of earth Sciences Carleton University Faculty of Geology and Geography Tomsk State University

Giant mafic dyke swarms are a key component of the feeder system of Large Igneous Provinces（LIPs）,large volume（>0.1 Mkm;;frequently above>1 M km;）,mainly mafic（-ultramafic）magmatic events of intraplate affinity.

The 1.78 Ga Xiong’er Volcanic Province(XVP) and coeval North China giant mafic Dyke Swarm(NCDS) are the most important magmatic events occurring after the amalgamation of the North China craton(NCC).The XVP consists of 3-7 km of extrusive volcanics and some feeder dykes/sills located along the southern margin of the NCC and extending over an area>0.06 M km .Compositions vary from basalt to rhyolite,but are predominantly intermediate in tenns of silica *** are also minor sedimentary intercalations and pyroclastic *** sedimentary interlayers indicate an environment changing from continental-facies to oceanic-facies *** XVP is characterized by fractional crystallization from an eM I type mantle source,and both continental arc(Andean-type) and rift environments have been *** NCDS is widespread in the central NCC with an outcrop area>0.1 M km,and are exposed at variable depths up to 20 km(deepest in the north).Dyke compositions vary from basalt to andesite and dacite,but are dominantly mafic,and comprise two series of *** studies revealed that the NCDS recorded assimilation and fractional crystallization of an eM I type magma source,with a minor DM contribution in the younger *** syn-collisional and infra-continental anorogenic environments have been *** and petrogenic correlations suggest a cogenetic relationship between the NCDS and XVP,and considered together,they define a Large Igneous Province(LIP) of>0.1 M km in area and>0.1 M km in volume,which is also notable for its continuous compositional range from mafic to felsic(with no gap at intermediate compositions).The petrology is explained by a common magma source that undergoes a silica-poor and iron-enriched fractionation trend at depth followed by a silica-rich and iron-poor fractionation trend in shallow-level magma conduits(dykes) and surface lavas.A mantle plume is favored as the cause of this～1.78 Ga North China LIP.
