Recognition Of Invertebrate Fossil Fragments In Rocks And Thin Sections

This unparelleled reference synthesizes the methods used in microfacies analysis and details the potential of microfacies in evaluating depositional environments and diagenetic history, and, in particular, the application of microfacies data in the study of carbonate hydrocarbon reservoirs and the provenance of archaeological materials. Nearly 230 instructive plates (30 in color) showing thin-section photographs with detailed explanations form a central part of the content. Helpful teaching-learning aids include detailed captions for hundreds of microphotographs, boxed summaries of technical terms, many case studies, guidelines for the determination and evaluation of microfacies criteria, for enclosed CD with 14000 references, self-testing exercises for recognition and characterization skills, and more

This is a book for beginners. Not geological beginners, because an introductory course in paleontology and some knowledge of the petrographic microscope is assumed, but for beginners in the study of the petrography of fossil constituents in sedimentary rocks. Fossils are studied for various reasons: 1) to provide chron ologic (time) frameworks, 2) to delineate rock units and ancient environments, or 3) to understand the past development (evolu tion) of living plants and animals. All of these uses may be at tained through petrographic studies of thin sections of fossils embedded in sedimentary rocks. Some knowledge of the appear ance of fossils in thin section is also fundamental for general stratigraphic studies, biofacies analyses, and is even useful in studying some metamorphic rocks. Commonly, fossils are essen tial for the delineation of carbonate rock types (facies or bio facies). We have written this book for sedimentary petrologists and stratigraphers, who routinely encounter fossils as part of their studies but who are not specialists in paleontology, and for students who are seeking a brief review and an introduction to the literature of the petrography of fossiliferous sedimentary rocks. Although experienced paleontologists may be appalled by the many generalized statements on size, shape, and principal fossil characters recited herein, we counter that we have had some success in introducing non-paleontologically oriented geologists to the use and identification of fossil constituents without using excessive paleontological terminology and detailed systematics.

More than half of the world's petroleum is to be found in carbonate rocks, for example in the Middle East, the former USSR and in North America. These rocks show a bewildering diversity of grains and textures, due in part to the wealth of different fossil organisms which have contributed to carbonate sedimentation, and in part to a wide variety of
