A map of major Precambrian mafic dyke swarms and related units in the North China Craton
is compiled, and the features and geological implications of these swarms are …

Abstract The Iapetus Ocean opened during the fission of the supercontinent Rodinia, from
the breakup of three of its core continental constituents: Laurentia, Baltica and Amazonia …

Regional groupings of a majority, or all, of Earth's crustal blocks have occurred several times
in Earth history, but only the most recent supercontinent Paleozoic Pangea/Gondwana, is …

Zircon and baddeleyite U–Pb ages and geochemistry of the Neoproterozoic mafic dyke
swarms at the northern margin of the Tarim Block, NW China, are reported here to decipher …

We report seven high precision U–Pb age determinations for mafic dykes from a number of
major Precambrian swarms located in the Dharwar craton, south India. These new age …

The Earth experienced fundamental tectonic transformation and paleoclimatic upheavals
during the early Paleoproterozoic (2.50–2.20 Ga). However, the tectonic framework of this …

In this paper we report zircon U–Pb age, chemical compositions of rock-forming minerals,
and whole-rock elemental and Sr–Nd isotopic data for the No. II mafic-ultramafic intrusive …

Mafic dyke is a sign of regional extension, and thus has important tectonic significance. A
great amount of mafic dykes occur in the Kongling terrain of the Yangtze Craton, which have …

We present baddeleyite U–Pb ages of Neoarchaean to Palaeoproterozoic dyke swarms and
the Mashonaland sill province in Zimbabwe. The 2575.0±1.5 Ma age of the Umvimeela dyke …

The volume of U-Pb geochronological data has increased rapidly in recent years in all types
of rocks. This trend has been possible thanks to developments in instrumentation with …
