With more than 192 full-color illustrations, this atlas permits virtually first-hand observations through a petrographic microscope of the most important and representative classes of sedimentary rock. Nine major sedimentary rock groups, such as sandstones, rudaceous rock, argillaceous rock, volcaniclastic rock, dolomites, siliceous rock, phosphorites, ironstones, and evaporites. An indispensable reference for professional geologists and undergraduate and graduate students enrolled in sedimentary petrology or petrography courses.
