“…14.1). Unconformity-related ores reflect a unique process of enrichment as the abundant uranium in older strata deposited under oxygen-deficient conditions was exposed and rapidly dissolved in an increasingly oxygen-rich environment (Robertson et al 1978). The ores comprise uraninite and pitchblende paleoplacers that predate evolution of a highly oxygenated atmosphere.…”

They formed in response to a complex array of geologic controls, notably the genesis of the sedimentary rocks that host most commercial energy resources. It is this genetic relationship between economic resources and environment that forms the basis for this book. Our grouping of petroleum, coal, uranium, and ground water may appear to be incongruous or artificial. But our basic premise is that these ostensibly disparate resources share common genetic attributes and that the sedimentological principles governing their natural distributions and influencing their recovery are fundamentally similar. Our combined careers have focused on these four resources, and our experiences in projects worldwide reveal that certain recurring geologic factors are important in controlling the distribution of commercial accumulations and subsurface fluid flow. These critical factors include the shape and stability of the receiving basin, the major depositional elements and their internal detail, and the modifications during burial that are brought about in these sediments by pressure, circulating fluids, heating, and chemical reaction.Since the first edition of this book in 1983, there has been a quantum leap in the volume of literature devoted to genetic stratigraphy and refinement of sedimentological principles and a commensurate increase in the application of these concepts to resource exploration and development. Two wholly new chapters, 11 and 16, have been added to accommodate these advances, two chapters (7 and 8) have been completely rewritten, and Chapters 3, 6, 9, 10, and 13 have been substantially revised.We review the spectrum of terrigenous (land-derived or siliciclastic as opposed to in-place or biochemical) clastic depositional systems and their component genetic facies, with emphasis on subsurface as well as field recognition. These range from the most proximal, subaerial, and generally coarse-grained alluvial-fan systems through fluvial, deltaic, shore-zone, ...

A brief review of some major types of Proterozoic metal deposits indicates that each type is characterized by a distinctive lithologic and tectonic setting. The main types of metalliferous ores considered are: volcanic-hosted massive sulfide deposits, sediment-hosted massive sulfide deposits, stratiform copper deposits, carbonatehosted lead-zinc deposits, magmatic copper-nickel deposits, and banded iron formations. Metal deposits in sedimentary and volcanic rocks dominate Proterozoic metallogeny, and it can be demonstrated that most formed in tectonic environments characterized by rifting. This association is reinforced by the time-space relationship between specific tectonic environments and metal deposits during Proterozoic time.Although Proterozoic metal deposits are distinctly different from the dominant types of late Phanerozoic deposits, these differences are considered to be primarily a function of erosion levels, and initial deep burial of syngenetic-type deposits. Finally, there seems to be no compelling evidence that tectonic styles or ore-generating systems were markedly different in the Proterozoic versus those of the Phanerozoic.
