“…The geometrical requirement to thin and extend the roll-over makes such compressional structures unlikely in simple cases and they probably only occur where flats are present in the footwall fault and where rotational strains are locally dominant. Such compressional structures are certainly seen in experimental systems and in small-scale growth faults and landslides (Crans et al 1980;Kirk 1982). At larger scales in areas such as the Viking Graben it is probable that their presence can be used to infer footwall ramps at depth although this remains to be demonstrated.…”

A new model for the structural development of extensional basins is outlined. The model suggests a close similarity in geometry between faults in high extension basins such as the North Sea and those in contractional zones. The geometric analogues are discussed and where necessary new terms are introduced to describe the structural style in the context of basin formation. Parallels are noted between contractional and extensional systems in deep crustal control on ramp and flat deformation zones which are now being interpreted from deep reflection work, e.g. MOIST and COCORP. The model is based on interpretation of industry seismic records particularly in the North Sea, and on field analogues of extensional faulting in the Basin and Range province of Nevada.

“…Contrasting with examples indicating movement on the regional tectonic faults, Kirk (1982) described Westphalian A gravity sliding near Kirkconnel (Sanquhar outlier, Fig. 1) that was stratigraphically restricted to one sedimentary cycle, and interpreted it as reflecting a local slope on a lake margin, with no regional significance.…”

The identification of syn-depositionally-active structures in the coal-bearing Upper Carboniferous of Great Britain

The Upper Carboniferous coalfields of Great Britain occupy various tectonic settings. Excellent data sets allow detailed analysis of any relationship between structure and the depositional patterns. Syn-depositional movement can be identified on a basin scale, and also at the scale of individual faults. However, with the exception of the Scottish Midland Valley, definitive evidence for syn-depositional movement on specific structures is relatively rare, and especially so in the English Pennine Basin. In particular, there is a general scarcity of detailed structural control on coal-depositional patterns. The environments in which coals formed would have been much more sensitive to subtle ground movements than the higher energy environments of the major channel belts. The precursor peats were widespread and commonly diachronous, and probably spanned around half the available time and space during Westphalian deposition across the Pennine Basin. The rarity of localized structural controls on coal patterns is therefore firm evidence of rarity of specific syn-depositional faulting throughout the sedimentary volume. Using mining data mainly from the Pennine Basin and the Midland Valley, this account discusses examples of likely, and less likely syn-depositional features, and proposes structural and sedimentological critieria for systematic assessment.Much of the British Silesian (Upper Carboniferous) is coalbearing, particularly the strata of mid-A to mid-C Westphalian age. Significant earlier coals are present in Dinantian and Namurian successions in northern Britain, while Westphalian D coals are widespread within the coalfields of southern England and South Wales (Fig. 1). The main sequences have been extensively explored and mined, and many publications describe the regional geology, structural setting, and sedimentology. However, there is little published on syn-depositional movements and associated structures, and the existing literature does not assess the prevalence, or rarity, of movement and its effects on deposition; naturally, authors have reported examples of likely movement, rather than its absence.

“…Specifics regarding dimensions and material compositions of the components can be found in Table 1. [4][5][6][7] [2]- [5] Each component comprising the Inline Pulse Tube Cryocoolers (IPTC) exhibits a cylindrical configuration, with all elements arranged in series to from an axis-symmetric system. Consequently, the IPTC is represented in a 2-dimensional, axis-symmetrical coordinate framework.…”

Inline Pulse tube cryocoolers (PTC) is very compact and achieved cryogenics temperature without moving part. In view of design, a cold heat exchanger where is provide surface cooling is placed between regenerator and pule tube. Due to that it become necessary to use secondary heat exchange. Coaxial pulse tube cryocoolers (CPTC)is design remove secondary heat exchanger. Helium is taken as working fluid. The required phase lag between mass flow rate and temperature, temperature and density contour are observed. Some Frequency results for different size of regenerator and pule tube are discussed.
