Crystals. Growth, morphology, and perfection / Кристаллы. Рост, морфология и совершенство

Crystals are solid materials having regular atomic arrangements characterized by periodicity and anisotropy. These properties are universally present, irrespective of whether the crystal is inorganic or organic, in living systems or in the inanimate world. Crystals exhibit various external forms, as represented by the elaborately varied dendritic forms of snow crystals or the hexagonal prismatic forms of rock-crystal. This variety of shape has stimulated scientific curiosity since the seventeenth century, since when intensive efforts have been made to understand the reasons why and how crystals can take a variety of forms <...>

CSA staff notice 43-302 - FAQs - NI 43-101 Standart of disclosure for mineral projects / Уведомление сотрудников CSA 43-302 - Часто задаваемые вопросы - NI 43-101 Стандарт раскрытия информации для проектов по добыче полезных ископаемых

NI 43-101 is a rule that governs how issuers disclose scientific and technical information about their mineral projects to the public. To assist mining industry participants and their advisors in understanding and applying NI 43-101, we compiled a summary of questions and CSA staff responses (Frequently Asked Questions or FAQs) that was first published on October 19, 2001 and was revised on February 8, 2002. Attached to this notice is an update to the FAQs.

We update the summary of FAQs from time to time to assist in the interpretation and application of NI 43-101 as new issues arise. We continuously update this summary of FAQs rather than create supplemental summaries in order to retain one repository of interpretative guidance for the rule. We intend to publish another comprehensive update later this year.

Cumulative Factors in the Generation of Giant Calc-Alkaline Porphyry Cu Deposits

The formation of porphyry Cu deposits in calc-alkaline magmatic arcs is considered to be the cumulative product of a wide range of processes beginning with dehydration of the subducting oceanic slab. No single process is key to the formation of large deposits, but the absence or inefficient operation of any contributory process, or the action of a deleterious process, can stunt or prevent deposit formation.

Current topics in structural geology / Актуальные темы в структурной геологии

This Special Issue marks the tenth anniversary of the very first issue of the Journal of Structural Geology. The idea of a specialist journal in structural geology was first conceived at a meeting in September 1977 between Paul Hancock of Bristol University and Peter Henn of Pergamon Press. In June 1978 Paul Hancock formally became Editor-in-Chief, joined soon after by Tony Barber as Associate Editor. They then recruited an Editorial Advisory Board and called for papers for the first volume. Those who responded by submitting papers to a then-unknown new journal are still remembered with gratitude, because by showing their faith they started the ball rolling <...>

Cut-off grades and optimising the strategic mine plan / Бортовые содержания и оптимизация стратегического плана добычи полезных ископаемых

Cut-off grade is perhaps the least understood driver of value for a mining operation. Many believe that it is determined relatively easily by knowing the mining and extraction costs, metallurgical recovery and an estimate of the price for the metal/s under consideration.

Das mammut. Mammuthus primigenius (Blumenbach) / Мамонт

Das Mammut, dessen fossiJe Beste m weiten Gebieten der Erde gefunden wurden, gehört zu den bekanntesten ausgestorbenen Tieren. Seit Jahrhunderten wurde Mammut-Elfenbein gehandelt und verwendet. Doch die in Schnee, Eis und Dauerfrostboden gefundenen Knochen erfuhren anfangs die verschiedensten Deutungen und waren Anlaß zur Entstehung zahlreicher Sagen und Märchen.

Data analytics applied to the mining industry / Аналитические данные в горнодобывающей промышленности

Adapting the mining industry with the technological changes is an exciting research subject [1,2]. Studied research about sociotechnical theory in an Australian mine site shows one of the first experiences to transition from hand-got mining to longwall methods. As a practical experience, this study illustrates a successful transition from a traditional mining method to an advanced process when socio-psychological and production influences grew over this technology transition [1].

Data Assimilation for the Geosciences From Theory to Application / Сбор данных для наук о земле. От теории к применению

Data assimilation plays a vital role in how forecasts are made for different geophysical disciplines. While the numerical model of the geophysical systems are critical, so are the observations of the same system, be they direct or indirect. Neither the model nor the observations are perfect, and both are required for an improved forecast than can be achieved through solely using the numerical model without guidance of how accurate the current state is, or through producing a persistence, or advection, forecast from observations. <...>
