The first edition appeared fourteen years ago. Since then there have been significant advances in our science that warrant an updating and revision of Sand and Sandstone. The main framework of the first edition has been retained so that the reader can begin with the mineralogy and textural properties of sands and sandstones, progress through their organization and classification and their study as a body of rock, to consideration of their origin-prove nance, transportation, deposition, and lithification-and finally to their place in the stratigraphic column and the basin. The last decade has seen the rise of facies analysis based on a closer look at the stratigraphic record and the recognition of characteristic bed ding sequences that are the signatures of some geologic process-such as a prograding shallow-water delta or the migration of a point bar on an alluvial floodplain. The environment of sand deposition is more closely determined by its place in such depositional systems than by criteria based on textural characteristics-the "fingerprint" approach. Our revi sion reflects this change in thinking. As in the geological sciences as a whole, the concept of plate tectonics has required a rethinking of our older ideas about the origin and accumu lation of sediments-especially the nature of the sedimentary basins.

Excerpt from Pennsylvanian of the Northern Mid-Continent Region The aggregate thickness of the Pennsylvanian in the northern part of the mid-continent region is to feet (610 to 914 meters). Southward there is a gradual increase in thickness to about feet meters) in eastern Oklahoma and west-central Arkansas. The total thickness of the Pennsylvanian in north-central Texas is approximately feet 24 meters). The general nature of these rocks in the northern and southern parts of the mid-continent region is essentially the same. The outstanding characters are the relative abundance of marine sediments, the extreme persistence and lateral uniformity of most of the stratigraphic units, and the occurrence of many comparatively thin formations of alternating shale, limestone, sandstone, and a few coal beds.
