a The age versus composite-depth plot for mid-depths of all palaeomagnetic samples, based on the correlation model: version 06 Apr. 2020. The error bars show ±1σ errors. The blue bars represent the intervals of the Laschamp (lower) and the post-Laschamp (upper) excursions. b The time variation of a basic resolution for each sample (a minimum time estimate for field-averaging) is calculated by dividing the thickness of a sample (2 cm) by a s.r. between adjacent sample levels. The low basic-resolution values are from core segments from parallel boreholes (3189 cm) and event (flood) layers (3350, 3358–3360 and 3384 cm). c Cross-section photographs of dry cubic samples after progressive THDs within Swing C of the Laschamp (i) and just below the Laschamp Excursion (ii). The original wet thickness of the sample is 2 cm (dry thickness is ca. 1.8 cm).
