... Bay regression event, and a newly observed but more severe disruption during the early Botomian, here named the Sinsk event. During the Sinsk event, the shallow-water benthos of the so-called Tommotian fauna, together with archaeocyaths and some trilobites, underwent a rapid decline. The Sinsk event...

... Sinsk event. The rifted Siberian and Laurentian cratonic margins are defined by truncations of basement aeromagnetic anomaly patterns (cf. Ross et al., 2000 ; Smelov et al., 2001 ), and by large basement ramps beneath foreland thrust and fold belts that mark the edges of the Cordilleran, Verkoyansk...

... C are recorded from shallow-water Nemakit-Daldynian to Atdabanian carbonates, as seen elsewhere on the platform. Rapid sea-level rise during the so-called "Sinsk event" led to starved-basin conditions from the middle Botomian ( Bergeroniellus micmacciformis Zone) to late Amgan ( Tomagnostus fissus...

Siderophile element abundances in these rocks correlate well with their Mg-numbers. The low-Mg rocks of the Chara–Sinsk dike swarm have the lowest abundances (ppm...

This model features a “hybrid” rift, when tectonic and magmatic processes coincide in time ( Stein et al., 2015 ). This combined model does not yet explain what causes magmatism to occur...
