文摘
- •
We studied 43 soils developed on volcanic material in Isla Santa Cruz (Galápagos, Ecuador)
- •
Several chemical indices are applied to determine the weathering intensity
- •
Weathering seems to be influenced by climate conditions controlled by altitude and orientation
- •
Soil elemental composition is also related to weathering and horizonation
- •
This research is an addition to the limited scientific knowledge of soils of the Galápagos Islands
