The roles of sea level and tectonics in controlling sedimentation and facies architecture are recurrent themes. Only the facies lateralis, with the protuberances on the margo dorsolateralis of the os dentale, is visible. It was not possible to study lateral facies differentiation at this site. There is little vertical facies differentiation through these clinobeds which have formed from a continuous amalgamation of deposits. Proximal/shallow clinoforms display round-edged exponential profiles, and changes in sediment fabrics and sedimentary structures along the clinoform, whereas vertical facies differentiation is limited. Most of the island consists of pervasively overprinted, greenschist-facies sequences. Temperatures of granulite-facies metamorphism: constraints from experimental phase equilibria and thermobarometry corrected for retrograde exchange. Most of the facies buccalis is obscured by matrix. The local hardening and stabilization of these grainsupported facies by the microbial crusts, allowed the growth of coral-microbial reef and coral-bearing thrombolites of variable size. This facies occurs as beds of coarse or medium to fine, normally graded sandstone between 0.3 and 1.0 m thick. The transitional lake facies association is characterized by its position between central and marginal lake facies associations. This boundary fault also induced fining-upwards vertical patterns and synsedimentary deformation in the marginal facies. Highly non-cylindrical folds and sheath folds with amphibolite-facies axial planar fabrics are locally developed. The albitized facies is enriched in secondary albite, arfvedsonite, annite and accessory zircon. Many contain coronitic and symplectitic textures indicative of partial eclogitization and retrogression from eclogite facies, respectively. But it goes beyond that; by introducing new concepts, particularly that of tectonic facies, this book will have wide applicability to other mountain belts. In all rock types, partial or complete retrogression to amphibolite-facies assemblages is evident. Therefore, granulite-facies assemblages would indicate metastability at high pressures if they pre-dated eclogite-facies metamorphism. The quartzofeldspathic orthogneisses contain metre-scale mafic pods with variably preserved eclogite facies assemblages. Facies assemblages are diachronous and their boundaries are parallel to the suballuvial bench. Here, the igneous and corona textures are obliterated by the growth of amphibolite-facies assemblages with hornblende, plagioclase, biotite, garnet and zoisite. The remaining 30 % of metabasites with amphibolite facies assemblages, many of which are sheared, contain no granulite relics. These chiefly represent major channel, floodbasin and extensive lacustrine and lake-delta facies within typical alluvial plain facies assemblages. These data were obtained for a single stratigraphic section by binning into four facies groups all beds that contained fossils. The book is far more than a mere description of sedimentary indicators of facies and of fossils as tracers of environment. These examples are from corpora and from sources on the web.
