Среди обширного материала из северо-двинских раскопок, оставшегося после смерти проф. Б. П. Амалицкого, имеется ряд скелетных остатков, которые могут быть отнесены к Формам из гр. Gorgonopsia Lyd. Из них два почти полных скелета в свое время были монтированы покойным профессором и выставлены в С.-Петербурге, один в 1900 г.5 (гр. Д»1 29), другой несколькими годами позже (IT>. Дя 97). Оба экземпляра были обозначены одним наименованием — Inostrancevia Alexandri Amal. Осталась также незаконченная рукопись покойного профессора с черновым наброском описания обоих скелетов, а равно еще одного черепа (гр. Д!> 70) и нескольких разрозненных костей, отнесенных Амалидким к тому же виду Inostrancevia. Им же были заготовлены несколько соответствующих Фотографий и три. прилагаемые нами, Фототипические таблицы (табл. I, I I и III). <...>

Grade control and ore/waste delineation in open pit mining operations was traditionally based on the comparison of estimated grades with an economic cutoff. In the 1990s, an alternative approach to ore selection was applied and established, taking into account financial indicators through the so-called economic classification functions in combination with grade uncertainty assessment.

Rocks that form the outer part of the Earth, the crust, provide a record of constant change in the Earth’s environment with time in relation to the movement and/or reaction of rock material during their formation. Thus, understanding the genesis of rocks is the foundation of the geological knowledge system. The nature, size, shape, properties and arrangement of constituent minerals gives rise to the diversity of rocks and their origin so that the challenge of geology is in determining their material source and mechanism of formation. Among the three kinds of rocks, igneous, sedimentary and metamorphic, the material source of metamorphic rocks need not be considered because its predecessor is also rock. Igneous rocks derived by crystallisation of liquids can be divided into mafic and felsic end members represented by gabbro/basalt and granite/rhyolite, respectively, with different sources <...>

This volume brings together a collection of papers that summarize current ideas and recent progress in the study of granite-related mineralization systems. They provide a combination of field, experimental and theoretical studies. Papers are grouped according to the main granite-related ore systems: granite-pegmatite, skarn and greisen-veins, porphyry, orogenic gold, intrusion-related, epithermal and porphyry-related gold and base metal, iron oxide–copper–gold (IOCG), and special case studies. The studies provide a broad spread in terms of both space and time, highlighting granite-related ore deposits from Europe (Russia, Sweden, Croatia and Turkey), the Middle East (Iran), Asia (Japan and China) and South America (Brazil and Argentina) and spanning rocks from Palaeoproterozoic to Miocene in age.
