ABSTRACT



This paper presents some data regarding controls of ore deposition in several Southeast Asian Laterites that have been studied from a standpoint of economic feasibility. Topographic control, lithological control, alteration and structural control are reviewed from several observations that have been obtained during the course of exploration. The presence of serpentine in the ultrama/ic rocks may be produced from weathering, deuteric alteration or hydrothermal alteration from later intrusive effects.
