Role of basin-wide landslides in the formation of extensive alluvial gemstone deposits in Sri lanka

Description :
The aim of this GIS- and field-based study is to demonstrate a basin(s)-wide relationship between landslide mass fluxes and the resulting extensive alluvial gemstone deposits of Sri Lanka. Rainfall-driven landslide activity may be a natural geological response affecting erosional equilibrium in high-relief tectonically stable terrains. Climatically forced base level changes will, over time, control sediment storage, removal or reworking in the valleys.
