This paper discusses the sociocultural phenomenon of slow travel and explores and clarifies definitional issues. The 30-year-plus antecedents of slow travel are examined. A literature review shows a concentration on four key features: slowness and the value of time; locality and activities at the destination; mode of transport and travel experience; and environmental consciousness. Links to the slow food and slow city movements are discussed, and evidence that slow travel is an important emergent form of tourism in Europe, accounting for 10% of the holiday market, is provided. A grounded theory approach continues the exploration, involving 23 in-depth interviews with practitioners and academics, which revealed that their core requirements for slow travel centred on slowness, the travel experience and environmental consciousness. There was a lack of consensus about the eligibility of car travel and high-speed rail. Slow travel is seen as a group of associated ideas rather than as a watertight definition; it is a mindset about travel rather than a tangible product and concentrates on lack of speed rather than slowness per se. The conclusion shows it to be a growing part of the sustainable tourism paradigm and proposes a working definition of slow travel.

A self‐adjusting curve‐matching computer program for the interpretation of magnetic anomalies produced by dike‐like bodies is described. The method yields an optimum set of dike parameter values by selecting a best‐fit model anomaly curve for a given set of discrete observed data along a profile across a two‐dimensional anomaly. The criterion used by the computer for the selection of a best‐fit curve may be either the linear or least squares condition. Convergence to either of these conditions requires the solution of a nonlinear problem. In the present case, solution is achieved by automatic trial and error modifications of an initial model. Selection of the initial model is based upon the shape of the observed anomaly; the proper choice of an initial model assures convergence of the error of fit to an absolute rather than to a relative minimum. The repeatability of the convergence of the iterative process can be tested by changing the initial model within the allowable ranges of variation of the dike parameters. Interpretations of finite strike length anomalies are achieved through the use of a correction curve. With this method, best‐depth estimates to the top of dike‐like bodies may be determined and for cases of induced magnetization, the effective susceptibility contrast and the dip of the dike may be calculated. Two practical applications of the method are presented.

The northeast trending Kapuskasing uplift transects the east-west belts of the central Superior Province over a distance of some 500 kin. Granulite to upper amphibolite facies rocks of the uplift form three distinct geological-geophysical entities: from south to north, the Chapleau, Groundhog River, and Fraserdale-Moosonee blocks. Uplift of the granulites along a moderately northwest dipping crustal-scale thrust fault is attributed to an early Proterozoic compressional event. Maior northeast-striking faults that bound the Kapuskasing zone on the west were examined by modelling of geophysical anomalies to determine dip and by geobarometry of garnetorthopyroxene-plagioclase-quartz assemblages to determine vertical displacement. Granulites in the Kapuskasing zone have 7-to 9-kbar signatures whereas those in the Quetico belt to the west indicate metamorphic pressure of 4-6 kbar. Individual calibrations of the barometer yield consistent pressure differences of 2-3 kbar, suggesting 7-10 km of west-sidedown movement on the faults. Modelling of gravity and aeromagnetic gradients indicates westerly dips of 60ø-65 ø , with west-side-down offset of up to 14 kin. These maior normal faults probably formed as collapse structures in response to crustal thickening which occurred Copyright 1986 by the American Geophysical Union. Paper number 6T023•. 0278-7•07/86/006T-023•$10.00 during the preceding compressional uplift stage. Differences in the configuration of individual blocks of the Kapuskasing zone can be related to variable fault slip and intersection angles between normal and reverse faults. Thus

Abstract'Slow travel' and 'slow tourism' are relatively new, but contested, concepts. This paper examines the meanings ascribed to them in the academic literature and websites targeted at potential tourists. It finds concurrence on aspects of savouring time at the destination and investing time to appreciate the locality, its people, history, culture and products, but detects different emphases. The academic literature stresses the benefits to the destination and global sustainability, while the websites focus on the personal benefits and ways of becoming a 'slow tourist'. Food and drink epitomise the immersion in and absorption of the destination and the multi-dimensional tourism experience, contrasted with the superficiality of mainstream tourism. The paper discusses whether tourists practising slow tourism without using the label are slow tourists or not.Keywords: slow travel; slow tourism; discourse. ResumoSlow travel e slow tourism são conceitos relativamente recentes, embora contestados. Este artigo examina os sentidos conferidos aos conceitos na literatura académica e websites dirigidos a potenciais turistas. Encontram-se consistências em aspetos como saborear o tempo no destino e investir tempo para usufruir do local, das pessoas, da história, da cultura e dos produtos, mas detetam-se ênfases diferentes. A literatura académica realça os benefícios para os destinos e sustentatibilidade global, enquanto os websites se dedicam aos benefícios pessoais e formas de se ser um slow tourist. Comidas e bebidas representam a imersão em e a absorção do destino e da experiência turística multidimensional, contrastando com a superficialidade do turismo de massas. O artigo discute se os turistas que praticam slow tourism sem recorrer ao rótulo são ou não turistas slow.Palavras-chave: slow travel; slow tourism; discurso. J. Guiver • P. McGrath |12

Previous gravity models of the Sudbury Structure (1850 Ma) were constrained by surface geology, and by density measurements of surface and borehole rock samples. Recent high‐resolution seismic reflection data provide additional constraints for modeling new gravity observations made along the Sudbury Lithoprobe transect. Results indicate, 1) density distributions constrained by the seismic data yield calculated gravity values matching the Bouguer gravity data, 2) the main sources of gravitational disturbance are external to the Sudbury Structure, 3) the positive gravity anomaly trend south of the Sudbury Structure is associated with mafic rocks of Proterozoic age, and 4) the large, ramplike, gravity anomaly paralleling the northwest margin of the Sudbury Structure is an expression of a northward dipping boundary within the Archean basement. The presence of a hidden mafic layer beneath the Sudbury Structure is not required to model the Bouguer gravity data. An enigma is an 8 mGal, positive, gravity anomaly over the south central Sudbury Structure.
