An open ocean record of the Toarcian oceanic anoxic event
Abstract. Oceanic anoxic events were time intervals in the Mesozoic characterized by widespread distribution of marine organic matter-rich sediments (black shales) and significant perturbations in
Marine osmium isotope record across the Triassic-Jurassic boundary from a Pacific pelagic site
The Triassic-Jurassic (T-J) boundary ca. 200 Ma represents one of the major mass extinction events of the Phanerozoic; however, the cause of this event remains controversial because of a paucity of
Global correlation of the radiolarian faunal change across the Triassic–Jurassic boundary
Precise comparison of the change in radiolarian faunas 3.5 m above a U-Pb zircon dated 199.6 ± 0.3 Ma tuff and approximately coincident with a negative δ 13 C anomaly in the Queen Charlotte Islands,
Origin of cyclicity in Triassic‐Jurassic radiolarian bedded cherts of the Mino accretionary complex from Japan
Abstract The abundance of magnetic microspherules in a Triassic-Jurassic continuous sequence of alternating chert and shale beds in the Mino accretionary complex, central Japan, was measured
