South Carolina, quarry near Cayce, United States
Soils
- Type
- Soil
Tertiary saprolite on a metadiabase dyke intruding granite, under a subtropical climate (now 1200 mm/yr and 18 C); smectite above 2 m, kaolinite below. Previously studied for Li, Mg, K, Fe and Cu. Aarons et al. (2023): uniform delta49Ti (weighted mean +0.070 ± 0.016 ‰), no measurable fractionation despite weathering.
