ABSTRACT. Neoproterozoic mafic dyke swarms are an important probe for reconstructing the evolutionary history of the Rodinia supercontinent. Here, we present detailed geochronological, geochemical, and Sr-Nd-Hf isotopic data to constrain the petrogenesis and geodynamic setting of Neoproterozoic mafic dyke swarms in the western Yangtze Block, South China.The trace fossil assemblage present is assigned to the Zoophycos ichnofacies and is of low/moderate diversity and comprises common Planolites, Chondrites and Thalassinoides, with occasional Scolicia and Zoophycos.

Hundreds of these fossils, very similar to the type ichnospecies, have been observed in Devonian to Cretaceous deposits.Zoophycos Massalongo, 1855 DESCRIPTION: Spreiten structures consisting of numerous distinct U-shaped, protrusive lobes of variable length, bordered by a marginal tunnel (i.e., causative burrow). Lobes coil spirally around a central axis, which may be a spreiten whorl structure. BEHAVIOR(S): Fodinichina; feeding burrows of deposit feeders.
