The number of fonts is indefinitely large and continues to grow. The difficulties of ordering them are associated with a wide variety of possible approaches to their descriptions, and the lack of a single basis for classification is also associated with this. Thus, fonts are grouped according to qualitative features: historical, plastic, purpose, t...

На базе информационного языка RHA, разработанного для разных типов объек- тов, предлагается систематизировать каркасы начертаний знакотипов "Н" раз- ных шрифтов, с назначением каркасу его кода, посредством помещения знакотипа "Н" в стандартизированное окно (ФонтОкно), и последующим расчётом количест- венных характеристик (характеризаций). Совокупно...

The authors propose to systematize the font frameworks of the ''H'' sign types of different fonts on the base of the RHA information language, which has been developed for different types of objects, by assigning a code to the framework by placing the H font in the standardized window (FontWindow), with the subsequent calculation of quantity charac...

Coding and ordering of fonts based on RHA information language – method. We propose a method for coding and ordering of Roman-type fonts after the distinguished "characteristic" letter H as satisfying the requirements of graphic expression for the ratio of face and proportions of different fonts. The following defining characteristics are highligh...
Article
The Jinping–Song Da rift structure in the Emeishan Large Igneous Province is composed of Permian high- and low-Ti volcanic and volcanoplutonic ultramafic-mafic associations of different compositions and genesis. High-Ti picrites, picrobasalts, basalts, and dolerites are enriched in LREE and depleted in HREE and show low Al2O3/TiO2 ratios (~4), comm...
Article
Late Permian PGE-Cu-Ni-bearing Iherzolite-gabbronorite-dolerite and dolerite-kongadiabase-granophyre intrusions of the Song Hiem rift structure in northeastern Vietnam (Cao Bang complex) formed synchronously with the Emeishan traps of the Yangtze Platform. Massifs of this complex are made up of rocks of two series: lherzolite-picrite-picrodolerite-...
Article
Compositions of parental magmas for some well-explored troctolite- anorthosite massifs of North America were estimated and numerically modeled using the COMAGMAT-3.3 software. The objects of study were the Kiglapait, Michikamau, and Harp Lake massifs of the Nain plutonic suite of the Labrador Peninsula (Canada), the Adirondack massif of the Grenvil...
Article
The Permian-Triassic komatiite-basalt complex in the Song Da rift, northwestern Vietnam, occurs in the axial part of this structure and includes komatiites, komatiitic basalts, olivine basalts, and subvolcanic bodies of dunite and plagioclase-bearin g wehrlite hosting Ni-Cu-PGE sulfide ores. Volcanic rocks contain olivine- and pyroxene-spinifex tex...
Article
Based on the classification of magmatic associations according to geochemical composition, komatiite-basalt, picrite-basalt, and picrite-dolerite complexes of different ages have been petrologically typified, and their typomorphic features have been studied. To estimate the compositions of mantle substrata of these complexes and the depths of forma...
Article
The Permo-Triassic ultramafic-mafic complexes in North Vietnam were mineralogically and geochemically specialized in the epoch of wide development of mantle magmatism on the territory of Central and Southeastern Asia. This paper describes sulfide Cu-Ni deposits related to high-Mg volcanoplutonic complex of komatiite-basalt composition (P2-T1) of th...
