概要	Geochronological dating is the determination of absolute ages of rocks and minerals using the decay of radioactive isotopes. Pioneered by Rutherford and Soddy (1902), this method provides numerical anchors for geological timescales and enables quantitative understanding of geological processes. Modern techniques (K-Ar, Rb-Sr, U-Pb, 40Ar/39Ar) span from recent to ancient events and are essential for calibrating relative chronologies and assessing rates of geological change.	Basin subsidence analysis is the quantitative study of how sedimentary basins deepen over geological time, driven by tectonics, isostasy, and load. Formalized by McKenzie (1978) and Sclater and Christie (1980), this method reveals the mechanical causes of basin development, predicts subsurface temperature and pressure histories, and constrains petroleum generation. Analysis integrates well stratigraphy, seismic geometry, gravity data, and thermal models to reconstruct basin evolution.	Stratigraphic correlation is the practice of identifying equivalent rock layers or chronostratigraphic units across space by tracing physical or chemical signatures. Rooted in 19th-century work on Alpine glacial sequences, this method was formalized in the 20th century by geologists like Vail who unified global sea-level change with depositional sequences. Correlation is foundational to basin-scale understanding of sediment transport, resource distribution, and paleoenvironmental change.
