Metamorphic evolution of ultrahigh-temperature granulite facies and upper amphibolite facies rocks of the Epupa Complex, NW Namibia
… by ductile shear zones: (1) Upper amphibolite facies rocks (Orue Unit) and (2) ultrahigh-temperature (UHT) granulite facies rocks (Epembe Unit). The rocks of the EC are transsected by a large anorthosite massif, the Kunene Intrusive Complex (KIC). The Orue Unit and the Epembe Unit were affected …

Hydrochemical facies study of ground water in the Tucson Basin
The concept of hydrochemical facies is used to study the distribution and, indirectly, to identify the origin of the chemical character of ground water in the basin-fill aquifer of the Tucson Basin in relationship to the hydrogeologic framework. Hydrochemical fades of ground water is defined …

MISSISSIPPIAN MUD MOUNDS OF DERBYSHIRE (ENGLAND, UK): FACIES ARCHITECTURE AND BIOTIC EVOLUTION
… Comparative investigation of mud mound lithofacies architecture, texture, and composition and brachiopod fauna in various depositional set-tings on the platform (north-eastern outer platform, intraplatform ramp, southern outer plat-form) allows investigating the factors influencing the growth …

Facies and provenance analysis of the Midcontinent Rift System (MRS) in Kansas
… in Kansas, relating variations in sedimentary facies to the different stages of rift development. Detailed facies and provenance analyses were carried out in discontinuous cores retrieved from the lower and upper successions (5395-11300 ft deep). Sixteen lithofacies were identified, grouped …

Petrophysical facies mapping of the Pennsylvanian Cline Shale, Midland Basin, West Texas.
… as determined from core-calibrated petrophysical facies across the study area. Nine depositional facies were observed and described from the cored Gunn36 #1 well located in Howard County. Five petrophysical facies were derived from the statistical comparison of core observed depositional facies …

Facies, Sequence Framework, and Evolution of Rudist Buildups, Shu'aiba Formation, Saudi Arabia
… lagoonal fine skeletal peloidal packstone; slope facies are fine skeletal fragmented packstone. Aggradational sequences 3 to 5 make up the composite sequence early highstand. Progradational sequences 6 and 7 are the composite sequence late highstand marking the deterioration of the Offneria rudist …

The effects of high temperature metamorphic and melting processes on granulite-facies rocks
… in petrological modelling of granulite facies rocks is reintegration of melt generated and lost during metamorphism. The aim of melt reintegration is to create bulk compositions suitable for modelling prograde subsolidus evolution. Melt reintegration methodology was applied to a …

Reconstructing climate from the Dead Sea sediment record using high-resolution micro-facies analyses
… Sea basin and (2) to apply high-resolution micro-facies analyses for reconstructing and better understanding climate variability from the Dead Sea sediments. Addressing the first aim, the sedimentary facies of the ~455 m long deep-basin core 5017-1 were described in great detail and characterised …

Stratigraphy and depositional setting of the Carrington shale facies (Mississippian) of the Williston Basin
<p>The Carrington shale facies is a radioactive illitic lagoonal shale, apparently deposited behind lime mudstone banks (Waulsortian bioherms), along the eastern margin of the Williston basin during Early Mississippian time.</p> <p>The Scallion subinterval, which is the basal subunit of the …

Cyclic peritidal facies of a Cambrian aggraded shelf: elbrook and conococheague formations, Virginia Appalachians
… were low (less than 3 cm/km); thus, subtidal facies developed in a mosaic pattern of lagoons and shoals, rather than in shore-parallel belts. When low areas filled, tidal flat laminites prograded seaward over subtidal units. Cyclicity may reflect spasmodic subsidence of the shelf, or uniform …
