The objective of this review is to summarise the characteristics, significance and evolution of heavy minerals and their accumulations, and to identify the key controls on the development and distribution of heavy mineral concentrations in alluvial systems. These controls can be broadly classified as tectonic setting, geomorphic setting and grain-scale concentrating processes, each of which is discussed. Based on this review, exploration models are developed which are designed to indicate favourable localities for the accumulation of heavy minerals, and trends likely to be exhibited within these accumulations. The models are structured from the broadest scale of target selection, down to the local scale of sample site selection. The major conclusion of this work is that an understanding of process geomorphology is required to develop genetic models of placer development, including a detailed evaluation of climatic fluctuations throughout the Caenozoic. Palaeoplacers such as the Witwatersrand goldfield, are inferred to have formed under similar circumstances of tectonic setting as genetically comparable Caenozoic placers such as those of Otago, New Zealand. The means of preservation of such major basins is however poorly understood.

The parallel development of archaeology and Quaternary geology in several regions of the world is reviewed, and common problems in dating and correlating alluvial sequences are discussed. Buried archaeological remains and radiometric dates provide a chronological framework for the sequence of Late Quaternary alluvial deposits in the central Jordan Rift. While previous studies emphasized a simple, two-stage model of Late Quaternary alluvial deposition, regional comparisons of the geomorphological contexts of archaeological sites of different ages indicate complex, multiple depositional and erosional cycles. These cycles were influenced by tectonism, climatic changes, human land use, and natural geomorphic thresholds, sometimes in combination. The stratigraphy and chronology of early agricultural settlements in the valley are summarized, and investigations at a protohistoric agricultural town are described. Major regional shifts in prehistoric and protohistoric patterns of agriculture and settlement are interpreted in terms of the impacts of changes in alluvial regimes. These correlations have implications for models of agricultural origins, and the stability and resilience of sedentary settlements in dry lands.
