Mapping calcretes in Inhambane province, Mozambique, for use in roadn construction

摘要

Calcretes have been used extensively in southern Africa, and elsewhere, for low-volume road construction. In Inhambane province of Mozambique, naturally occurring gravels are rare and calcrete is used wherever it is known to occur in reasonable proximity to the road network. While considerable research and development has been undertaken in Botswana, Namibia, and South Africa on the prospecting and engineering usage of calcrete, little work has been undertaken in Mozambique.
