- ‘A series of new findings are now available, which permit the general Jurassic stratigraphy of Jabal Akhdar to be significantly refined.’
- ‘Tertiary stratigraphy throws considerable light on landform and river development.’
- ‘This initial stratigraphy is used as the platform to investigate the lava flow faciès distribution in more detail and from there to construct a 3D geological model of the lava field heterogeneity.’
- ‘The geological mapping allowed a detailed revision of the regional stratigraphy.’
- ‘The relative chronology derived from the radar stratigraphy clearly shows that the dune has migrated from east to west.’
- ‘But unless you have already mastered vertebrate anatomy, Mesozoic stratigraphy, and phylogenetic analysis, it's probably not the place to begin.’
- ‘Although Lower Cambrian stratigraphy remains in a state of some uncertainty, therefore, it is possible at present to present a provisional view of the sequence of events in at least some areas of the world.’
- ‘Lysons did not fully understand stratigraphy, and he mistook the date of the villa.’
- ‘Inspiration is gained from the actions of the archaeologist, using stratigraphy as a recording practice, that records spacio-temporal paradigms.’
- ‘In the final section Bosence and Wilson discuss the complexities of sequence stratigraphy in carbonate settings and introduce the use of numeric stratigraphic modeling for facies prediction.’
- 1.2 The structure of a particular set of strata:‘you can find materials at the surface which are samples from the deeper stratigraphy’
- ‘The late Mesozoic and Cenozoic stratigraphy of northern Chile is shown in Figure 3.’
- ‘Completing the exhibitions is a diorama of the geology of the area north of Johannesburg, the Magaliesburg area, that shows details of the region's topography, geology, and stratigraphy.’
- ‘Several other interruptions within the Cenozoic stratigraphy of the Zagros region have long been attributed to epirogeny.’
- ‘The ophiolite contains a complete igneous stratigraphy of serpentinized ultramafics, gabbro, sheeted dykes and pillow lavas, as described by Moores.’
- ‘These rocks are generally divided into two major types in view of their lithology, internal stratigraphy and contact relationships with surrounding rocks.’
- ‘For details of reflection characteristics, especially in the Mesozoic stratigraphy, the reader is referred to the literature cited above.’
- ‘Recent work on Upper Cretaceous sequence stratigraphy in European basins has demonstrated that chalks provide valuable information on short- and long-term sea-level change.’
- ‘Oscillating reactions are thought to play key roles in biological morphogenesis and geologic stratigraphy.’
- ‘The geologic setting and stratigraphy of the Cape Phillips Formation were noted by MacDonald.’
- ‘In this study we concentrate on the field relations and stratigraphy of the pyroclastic deposits within the lower volcanics.’
- ‘At the museum, Cooper worked in contact with U.S. Geological Survey paleontologists whose concerns were brachiopods and Lower Paleozoic stratigraphy.’
- ‘The overlying Pliocene reflections display a regular layer-cake stratigraphy of downwarped reflections defining a U-shaped depression.’
- ‘The accepted stratigraphy of the Dalradian block is presented in Figure 1.’
- ‘Despite the relatively coherent chronological stratigraphy demonstrated at the ice patches, temporal gaps are evident.’
- ‘The volcanic stratigraphy, consisting dominantly of flood basalts with interbedded pyroclastic deposits, is well-exposed in East Greenland.’
- ‘Conversely, there is during this time interval a general scarcity of erupted igneous rocks that can be reliably tied into relative stratigraphy.’
- ‘Due to the cave's deep, complex stratigraphy, the geological context of associated material culture has been particularly challenging to interpret.’
- ‘A second constraint on the timescale of canyon filling relates to the cyclic stratigraphy documented at the Umberatana syncline example.’
- ‘The sills are structurally disrupted by the same tectonic features that imbricate other elements of the Bainang terrane stratigraphy.’
- ‘The recognition of an orogenic unconformity at the base of the Easdale Subgroup allows for a more realistic overall interpretation of Dalradian stratigraphy.’
