Some 75% of the rocks at the Earth’s surface are sedimentary in origin, and these include the familiar sandstones, limestones and shales, and the less common but equally well-known salt deposits, ironstones, coal and chert. Sedimentary rocks of the geological record were deposited in the whole range of natural environments that exist today. The study of these modern environments and their sediments and processes contributes much to the understanding of their ancient equivalents. There are some sedimentary rock types; however, for which there are no known modern analogues, or their inferred depositional environments are only poorly represented at the present time.
During the past two to three decades, the scanning electron microscope (SEM) has become established as an essential tool in the study of sedimentary rocks, sediments, and soils. It provides a useful complement to the traditional role of the petrographic microscope, which became popular after the pioneering work of Henry Clifton Sorby in the second half of the nineteenth century (Sorby, 1877a,b, 1878).
Our modern society has a constant need for raw materials and energy. An on-going effort in exploration and research is necessary, therefore, to discover and develop them. And, in this effort, it is better to appeal to geology than to rely on chance.
Clays are one of the most important groups of minerals that destroy permeability in sandstones, but they also react with drilling and completion fluids and induce fine-particle migrationduring hydrocarbon production. They are a very complex family of minerals that commonly are mutually intergrown and contain a wide range of solid solutions and form by a wide range of processes. They form under a wide diversity of pressure and temperature conditions, as well as rock and fluid compositional conditions.

In recognition of the increasing interest in the subject of deformation of sediments and sedimentary rocks shown by Earth scientists in recent years, a major international conference with this theme was held at University College London in April 1985. This volume contains the texts of those contributions to the Conference that were submitted for publication.
Research on base metal sulfide deposits is among the oldest and best-documented subjects of economic geologists worldwide, considering that copper was first mined about 3000 years ago on the island of Cyprus.
During the past 10 years, after the exciting discovery of active sulfide formation on the modem ocean floor, a considerable flow of new ideas has stimulated and influenced the discussion of oreforming processes for copper-zinc-Iead sulfides in sedimentary and volcanic environments. The development of new genetic concept sconsequently led to reinterpretation of some apparently well-established formation models. <...>

The Guaritas sequence is the uppermost stratigraphical level of the Camaqua Basin (southern Brazil) and comprises an alluvial, deltaic and aeolian continental facies association up to 800 m thick. Facies mapping of this unit has revealed a lateral association of tributary fans and trunk braided rivers developed under semi-arid conditions.
