Walcot Gibson was born at Bromsgrove, Worcestershire, on 24 August 1864. His father was a bank manager from the north country and his mother was Cornish, and they had three sons and one daughter. Gibson was educated at the Bromsgrove School and about 1882 went to Mason College, Birmingham, now the University of Birmingham. Charles Lapworth who had distinguished himself by his great researches in the south of Scotland had just been appointed to the chair of Geology at Mason College and thirty-one years later (1913) he records that Gibson was his first geological pupil. His interest in geology and geological mapping was developed by intimate contact with Lapworth and was sustained by a coterie of ardent amateur geologists, among them Joseph Landon, Fred Cullis and C. J. Gilbert. This period clearly determined Gibson’s choice of a career. After a course at the Royal College of Science he set out in 1889 on Lapworth’s advice for South Africa where he was engaged for two years on mineral surveys in the Rand goldfields and elsewhere. From there he moved to East Africa where he was engaged for another two years on mineral surveys for the East Africa Company. He returned to this country an experienced geologist and surveyor and in 1893 he joined H.M. Geological Survey in which service he remained for thirty-two years until his retirement in 1925. This was an important period in the history of the Geological Survey for owing to strong representations that the old Survey had become obsolete both in topography and geology, the House of Commons in 1891 sanctioned a resurvey of the great South Wales Coalfield on the scale of six inches to the mile. The first mapping of that field initiated by Logan and de la Beche was on the one-inch scale and was completed about 1845, the year in which the Geological Survey was transferred from the Board of Ordnance. The enormous developments which had taken place since the original survey had far outstripped the knowledge of the geological structure of the field and new information had become urgently necessary.

The object of the Geological Survey is to ascertain in detail the geological structure of the United Kingdom, and to publish the results in maps, sections, and descriptive memoirs. The Ordnance maps form the groundwork on which these geological investigations proceed; and as no district is examined until these maps are ready, the progress of the Geological Survey is guided in no small degree by that of the Ordnance engineers. In Scotland, the geological mapping has hitherto been conducted wholly upon the county maps on the scale of six inches to a mile, and the advantages of so large a scale are such, that although the work is finally reduced and published on the scale of one inch to a mile, no county is surveyed until its six-inch maps are ready for use.

The island of Crete is situated near the front of an active plate margin. Therefore, it is of great interest in the framework of the International Continental Drilling Project (I.C.D.P.). A short review of the digital modelling methods, their applications in the geosciences and the associated advantages is also presented. The digital 3-dimensional geometric model of the geological structure of the Samaria Gorge region is based on the study of the stratigraphy and the tectonic evolution of the metamorphic rocks of the Plattenkalk group in SW Crete. Data from the geological map of Greece (Vatolakkos sheet, 1:50.000) and from the literature have been supplemented by geological mapping and structural analyses. In our study we applied interactive 3D CAD methods implemented in the integrated software package SURPAC2000. The surface geology has been draped over a digital elevation model of the topography in order to model the geometry of the subsurface structures. Two hypotheses about the geological structure of the region are examined: a) the one given by the existing geological map, which proposes a syncline structure and b) the one resulting from the combination of existing data, corrections carried out through repeated 3D simulations and new field observations. After distinguishing in the S of the study area the Trypali union, overthrusted on the Plattenkalk group, we propose an anticline structure with a NNE/SSW striking axis dipping to the NE.

<p>Gravity Satellite has been widely used in tectonic studies and regional of geological mapping. The Satellite Gravity data are provided free by Scripps Institution of Oceanography, University of California San Diego. The data are acquired by GEOSAT and ERS-1 satellites with a 1.5 km resolution for one pixel. For a further application, the tilt derivative analytic technique was used in order to enhance linear trends of the geological structure revealed by the Bouguer anomalies. The method is represented by the value of an angle between the total horizontal and vertical derivative from the gravity data. The results show that the tilt derivative calculation has been able to map clearly some geological structures on the north of Sumatra i.e., the Aceh and the Seulimeuem segments, as well as some local faults around them. On the other hand, Banda Aceh as the capital city of Aceh Province and Pidie District is dominated by positive values of the tilt derivative anomalies. The data coincide with geological maps of both areas where they are covered by alluvial deposits. Based on the result, it can be concluded that the tilt derivative method is potentially used for quick interpretation of the satellite gravity data.</p>

The study area represents a small part of the Lesser Himalaya in western Nepal and lies about 346 km west from Kathmandu. It covers 250 km area representing some parts of Gulmi and Baglung districts. The area was selected for the present study on the impression from the previous geological map that has showed some metallic mineral resources like iron, copper and lead in the region. Similarly, studies reveal that there is very complicated geological structure which raised the interest for the study. Main objective of the study was to prepare a geological map of the area in a scale of 1:25,000 and study the possible mineral deposits. An extensive geological mapping was carried out in the field covering at one data within one centimetre of the map scale and large number of samples was collected for the petrographic as well as ore genesis studies. The rocks of the region were mapped under two geological units as the Nourpul Formation (older) and the Dhading Dolomite (younger).  There are a series of folds in the area. From regional to micro-scale all folds are trending towards east-west. The Badi Gad Fault and the Harewa Khola Thrust are the regional scale thrust mapped in the area. The Badi Gad is considered as a strike-slip in nature. The Harewa Khola Thrust is probably an imbricate fault. It has propagated to the north which is out of sequence in nature. Some metallic minerals like copper and iron along with old working mines were observed during the study. Occurrences of copper and iron mineralization has been mapped and described. Present study revealed that copper mineralization is limited within the veins and boudinage forms as hydrothermal deposit while the iron is tabular and syngenetic in nature.

The career of Jean-Baptiste-Julien d'Omalius d'Halloy (1783-1875), commencing with brilliant scientific activities and proceeding to his attainment of the highest administrative and political positions, in itself demonstrates that he was an exceptional individual. His scientific career started with a long voyage through the French Empire and adjacent regions, during which he gained an understanding of the geological structure of most of Europe. The geological map he compiled based on his travel notes formed the basis of all future geological maps in the areas that he covered. After the independence of Belgium in 1830, André Dumont was made responsible for the mapping of the whole country, resulting in the publication of a 9-sheet map of Belgium in 1853 on a scale of 1:160.000. In 1878, Belgium decided to produce a more detailed map on the scale of 1:20.000, entrusting the work to Edouard Dupont., but as this appointment was controversial and the mapping at this scale was abandoned and than, the newly created Geological Survey of Belgium published a new 226-sheet map on a scale of 1:40.000. Starting from 1993, after the federalisation of the country, new geological maps of the regional states are mapped and produced.

Drawing on the fieldwork undertaken on behalf of the Austrian Geological Survey in the 19th century, I should like to analyse those practices that may be understood as ‘administration procedures’. Using a variety of selected handwritten materials that were produced during fieldwork in the context of the geological mapping project (1848-1867) of the Habsburg Monarchy, commissioned by the Royal Imperial Geological Survey in Vienna, I should like to examine the route from subjective observation to written documentation, the conceptualization of experience and the strategies of writing, and also the procedures for standardization. Through this perspective, fieldwork becomes a procedure that is materialized on paper. Every piece of fieldwork involves, in principle, countless administrative acts and procedures. These are preceded by the instructions which, in functional terms, occur at two different levels. One level provides a methodology for the acquisition of knowledge; the other level concerns the bureaucracy, or the organizational framework, within which the fieldwork takes place. On the one hand the investigator is seeking to optimize the acquisition of knowledge, whilst on the other hand the checking of both the subject and the object of the investigation is a concomitant feature of both levels.

The radio installations at Culgoora Observatory evolved from the work carried out at Dapto field station between 1952 and 1965—which in turn was based on earlier observations. The basic instrument at Dapto was a radiospectrograph which produced two solar spectra per second over a frequency range originally of 40-210 MHz and finally of 5-2000 MHz. Until 1957 the Dapto radio spectrograph was the only one operating in the world and it fell upon this instrument to reveal many of the spectral phenomena which are now well known. The spectrograph observations referred to the total flux from the Sun observations with high directivity began at Dapto in 1958 with the introduction of a swept-frequency interferometer which measured the one-dimensional (east-west) positions of bursts and their approximate angular size over a continuous range of frequencies between 40 and 70 MHz. The results obtained from this combination of spectrograph and interferometer indicated that great advances would be made in our knowledge and understanding of the phenomena if two-dimensional metre-wavelength pictures of the Sun could somehow be recorded at short time intervals of about Is—again in combination with spectrographic observations. This requirement led to the start of the radioheliograph project. One requirement for this instrument was a site with linear dimensions of the order of 3x3 km. This was far too large for the Dapto site and a new site was selected at Culgoora in the north-west plains of New South Wales. The virtues of this site are its size, flatness, freedom from flooding, low radio noise level and accessibility from Sydney by air transport. Its sunshine and optical-seeing properties also made it a highly desirable site for optical observations, and developments assumed a new significance when Dr. Giovanelli and his optical colleagues decided to join us at the same observatory.

The world practice of distance learning has updated the educational technologies that are adequate to the challenges of today and can effectively solve the problems of training competitive specialists in the new information society. Among them, visualization is singled out, which improves the quality of perception, understanding and assimilation of educational material and serves as a powerful motivator of the students’ cognitive activity. The study is aimed at characterizing the potential of visualization as a technology for teaching Pedagogy students, which allows using the tools of the digital environment effectively to achieve educational goals. The main research method is the survey of 96 second-year bachelor-degree students of the subject area “Pedagogical Education” of the Faculty of Philology of the North-Eastern Federal University. A quantitative and qualitative analysis of the results of the research on visualization as educational technology has revealed the interest of future teachers in using visual teaching methods and understanding the role of visualization in enhancing the cognitive activity of students. The respondents have demonstrated, on the one hand, knowledge of the basic means of information visualization (88%). Yet, on the other hand, not all of the respondents (55%) can clearly and consciously differentiate the concepts of “online platform”, “social network” and “visual means of transmitting information” (“visual communication”).

The Magnesian Limestone of England forms a comparatively narrow outcrop stretching southwards for about 150 miles from South Shields to Nottingham. At either end the formation is fairly well known from the many quarries and sections opened up in the industrial areas of East Durham on the one hand and South Yorkshire and Nottinghamshire on the other. Away from these regions, however, our knowledge is scanty, and particularly so in the North Riding of Yorkshire, in the tract of country between the rivers Tees and Swale. Information is lacking mainly because the district is so thickly covered with Glacial and Recent deposits that, except at the extreme ends of this Tees-Swale stretch, rock is nowhere exposed. All the way from the Darlington country down to Catterick and beyond, for sheer lack of evidence the Trias—Magnesian Limestone boundary was assumed to be of normal, unfaulted character, but all was so uncertain that any borings in the area were likely to prove invaluable. How invaluable will be gathered from the following account of two recent bores, which throws an entirely new light, not only on the geological structure but also on the stratigraphy of this obscure region.

The “Tarskavaig-Moine” schists occupy a small area in the Sleat district of Skye, extending southwards from Tarskavaig to the Point of Sleat, a distance of about seven miles, with a maximum width of outcrop of two and a half miles between the coast on the west and structurally overlying formations on the east. Their tectonic relationships and petrographic characters were first described in detail by C. T. Clough in the Geological Survey Memoir on the North-West Highlands of Scotland (1, pp. 589–594, and pp. 618–621). The northern part of the outcrop falls in Sheet 71 of the one-inch geological maps, and is described in the accompanying memoir (2); the southern part falls in the unpublished Sheet 61. Later publications summarize these earlier discussions (3, p. 171; 4, p. 309; 5, p. 23); the last named includes a map of the whole outcrop, on a scale of two miles to an inch, simplified from manuscript maps by Clough. A summary of the tectonics and metamorphism has recently been published by Dr. E. B. Bailey (6).
