Astronomically tuned chronostratigraphy of an Upper Triassic–Middle Jurassic lacustrine succession in Southwest China

Key Points

• Chronostratigraphy defines sediment layers, uncovering geological timelines linked to environmental changes.
• Key evidence includes detailed analyses of lacustrine sediments spanning the Upper Triassic and Middle Jurassic periods.
• This observational analysis highlights stratigraphic patterns across multiple sediment cores in Southwest China.
• Findings support the understanding of ancient aquatic environments, vital for reconstructing Earth's climatic history.
