Palimpsests are large, circular, low-relief impact scars on Ganymede and Callisto. These structures were poorly understood based on Voyager-era analysis, but high-resolution Galileo images allow more detailed inspection. We analyze images of four Ganymedean palimpsests targeted by Galileo: Memphis and Buto Faculae, Epigeus, and Zakar. Ganymedean craters and Europan ring structures are used as t...

In order to clarify the sedimentary development law under Cambrian Ordovician regional stratigraphic framework in Tadong area, and lay a theoretical foundation for further oil gas exploration study area. The distribution, characteristics evolution of main facies belts are studied by means drilling core observation, cast thin section identification, logging curve feature analysis, seismic profil...

Abstract The Middle Jurassic syn-rift sediments of the Khatatba Formation contain not only principle source rock organofacies in north Western Desert (NWD), but also several potential sandstone reservoir targets. However, controls on quality facies and spatiotemporal evolution types (RRTs) are still blurred. This study integrates seismic, wireline logs, conventional core data from some wells Me...

Combined with the characteristics of well pattern high density and abundant dynamic static data, application well-seismic technology in tapping potential remaining oil can improve exploitation level oil. Through fine structural interpretation hierarchical method, practical combination is discussed. Well-seismic depicts sedimentary facies, analyzes sand body characteristics, uses digital reservo...

PROLOGUE This resubmission has benefited from constructive input by 8 mail reviewers, a panel summary, and NSF feedback (fall 2011). In response, we amplify three issues: 1) 3D imaging will detect nearshore features (e.g., meandering rivers, estuary complexes, lagoons/barrier islands, incised shelf valleys, etc.) that can be tied to IODP Exp313 sites M27-M29; mapping these features and associat...

The granulite facies assemblages of the anorthositic rocks of the Bergen Arcs (stable at 800 -900°C and 10 kbar) have been transformed to eclogite facies assemblages (stable at 700 -750°C and 16-19 kbar) in the vicinity of Caledonian shear zones. This section of the root zone of the Caledonian mountain chain reveals a deep polymetamorphic crust where Precambrian granulites (mean density 3.02 g ...

Principal results: Site 1073 constitutes one of four second-priority sites approved for drilling that were to be undertaken in the event that either time allowed or that operations had to be curtailed at both primary shelf sites. With 5 days remaining on Leg 174A, the decision was made to move to the slope, because it seemed unlikely that at Sites 1071 and 1072 it would be possible to reach obj...
