В работе рассмотрены два основных круга задач, основанных на использовании структурных моделей в инженерной геологии: исследование и описание неоднородности массивов горных пород и вопросы теории разведки и опробования. Исследование неоднородности осуществлено эмпирически на большом фактическом материале, охватывающем разнообразные свойства горных пород в различных геологических условиях.

The book lays emphasis on ore deposit set ups, structural permeability and proximity indicator minerals that have relevance in assessing mineral potential of prospective terrains. It also covers aspects of geophysical framework, data acquisition and challenges posed by the declining rate of new mineral discoveries of economic significance.

Geological maps represent the solid geology at the Earth’s surface unconcealed by vegetation, soil or buildings (figure 1a). Different rock types and formations are illustrated by different colours and/or symbols. Other features such as faults, mineral veins, coal seams, marker horizons and landslips are shown. Bedding and structural features such as cleavage and foliations are indicated by strike and dip or plunge and azimuth symbols (figure 1b).

We are very familiar with topographic contours of landforms. Since landforms are complex surfaces, topographic contours (and bathymetric contours below water level) follow contorted paths tracing out a horizontal line on the map. It is often convenient to imagine oneself “walking out contours” and so visualize the land surface and its slopes. The closer contours are spaced, the steeper the surface. Occasionally contours merge, one above the other, where a cliff is located.

Geologists have long maintained that their discipline differs strikingly from chemistry and physics in being historical. There has been almost no explicit consideration by geologists, however, of the particular methodological problems imposed by the historical dimension. Historians and philosophers, on the other hand, have considered the problems of historical method at great length, and in recent years there has been, it seems, an increased interest in the methodology and philosophy of history. It is my purpose here to consider the extent to whieh the issues raised in recent discussions of explanation in human history are pertinent to the problem of explanation in historical geology. Because paleontology presents special methodological problems that I shall later discuss in detail (see pp. 148-70), Ihave omitted at this point any consideration of geological explanations containing paleontological concepts. <...>

The Gull Rapids area, Manitoba, lies on the Superior craton margin and forms part of the Superior Boundary Zone (SBZ), a major collisional zone between the Archean Superior craton and the adjacent Paleoproterozoic Trans-Hudson Orogen. There are two main rock assemblages at Gull Rapids: orthogneisses (of possible Split Lake Block origin) and supracrustal rocks (metavolcanic and metasedimentary). Late, crosscutting felsic and mafic intrusive bodies (mostly dykes and sills) are used to constrain the relative and absolute timing of deformation and metamorphism.
