Map projections - a working manual / Картографические проекции - руководство по эксплуатации

After decades of using only one map projection, the Polyconic, for its mapping program, the U.S. Geological Survey (USGS) now uses several of the more common projections for its published maps. For larger scale maps, including topographic quadrangles and the State Base Map Series, conformal projections such as the Transverse Mercator and the Lambert Conformal Conic are used. Equal-area and equidistant projections appear in the National Atlas.

Geology of the Adventdalen map area (With a geological map Svalbard C9G 1: 100 000) / Геология района Адвентдален на карте (С геологической картой Шпицберген C9G 1: 100 000)

The map area, covering 2,250 km", lies in the central part of Spitsbergen, south of Isfjorden. Geological investigations were started by Swedish expeditions in the last half of the 19th century, and the work was continued in the present century mainly by Norwegian expeditions. The region is mountainous, moderately glaciated, but shows a juvenile glacial morphology. The climate is polar. The rock sequence exposed in the area is c. 3,400 m thick and consists of two Permian, six Mesozoic, and six Tertiary formations. The Permian deposits are mainly eherts , cherty limestones, limestones, and sandstones deposited under marine conditions. The Mesozoic-Tertiary sequence is composed generally of shales, siltstones, and sandstones deposited mainly in marine environments, and to a lesser extent under terrestrial conditions. Surficial deposits of Quaternary age are largely of glacial, colluvial, alluvial, and marine origin <...>

Dual random fields and their application to mineral potential mapping / Двойные случайные поля и их применение для картирования потенциала полезных ископаемых

In various geosciences branches, including mineral exploration, geometallurgical characterization on established mining operations, and remote sensing, the regionalized input variables are spatially well-sampled across the domain of interest, limiting the scope of spatial uncertainty quantification procedures. In turn, response outcomes such as the mineral potential in a given region, mining throughput, metallurgical recovery, or in-situ estimations from remote satellite imagery, are usually modeled from a much-restricted subset of testing samples, collected at certain locations due to accessibility restrictions and the high acquisition costs.

Geologically-constrained mineral potential mapping (Examples from the Philippines) / Геологически-ограниченное картирование минерально-сырьевого потенциала (примеры на Филиппинах)

Many Third World and developing countries rely mainly on the utilisation of their natural resources to sustain their economic development. In the Philippines in particular, the exploitation of mineral resources has traditionally been a significant component of the Philippine economy (Domingo, 1993).

Predictive spatial models for mineral potential mapping / Прогнозные пространственные модели для картирования потенциала полезных ископаемых

Modelling and prediction of spatially distributed data such as the secondary cassiterite mineral distributions are often affected by spatial autocorrelation (SAC); a phenomenon that violates attributes data independence in space, which leads to type1 errors in classical statistics and overfitting or underfitting in machine learning (ML) classification respectively. The concept of overfitting and underfitting of spatially distributed datasets in an ML classification has not been properly addressed by the traditional random holdout technique of model validation, and this is a challenge to the assessment of predictive spatial model performance in spatially distributed datasets.

Introduction to structural geology. Workbook 3. Geological maps / Введение в стурктурную геологию. Рабочая тетрадь 3. Геологическая карта

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).

Lithospheric architecture and precambrian  geology of the Hoggar and adjacent areas. A reference case for mapping and modeling  in geosciences / Архитектура литосферы и геология докембрия Хоггара и прилегающих районов. Справочный материал для картографиро

The Hoggar, which forms the Algerian part of the Tuareg shield, is an ideal site for geoscientific studies. As the site of successive orogenies, it offers a single example of the problems that arise on a continental scale, whether in terms of magmatism, metamorphism, structure, metallogeny or geophysics.

Geologic modeling and mapping / Геологическое моделирование и картирование

Subsurface fluid flow is critically dependent on the 3D distribution of petrophysical properties in rocks. In sequences of sedimentary rocks these properties are strongly influenced by lithology and facies distribution that stem from the geologic processes that generated them.

Mapping Mongolia. Situating Mongolia in the world from geologic time to the present / Составление карты Монголии. Положение Монголии в мире с геологических времен по настоящее время

When I first started conducting research in Mongolia, I found that I could make a room full of anthropologists jealous by telling them where I worked. To a discipline whose members pride themselves on working in exotic locations, Mongolia is a glamorous research site, for few Western and even fewer American anthropologists had worked there during the Cold War.1 Young anthropologists started to trickle in during the early 1990s: Norwegian, Danish, and French graduate students; Christopher Kaplonski, Peter Marsh, and Katherine Petrie from the United States; and, of course, the University of Cambridge research group (Mongolian and Inner Asian Studies Unit) headed by Caroline Humphrey and now David Sneath. So anthropology, my discipline, was becoming interested in Mongolia.

Weaving a national map: a review of the U.S. geological survey concept of the national map / Создание национальной карты: обзор концепции национальной карты геологической службы США

This report responds to a request by the U.S. Geological Survey (USGS) that the National Research Council (NRC) review its concept of The National Map. The National Map is envisioned by USGS as a database providing “public domain core geographic data about the United States and its territories that other agencies can extend, enhance, and reference as they concentrate on maintaining other data that are unique to their needs” (USGS, 2001).
