#composition
- Adamellite — A coarse-grained plutonic igneous rock, considered a specific variety of granite or quartz monzonite, in which potassium feldspar and plagioclase feldspar (especially oligoclase or andesine) are present in approximately equal amounts. This crystalline rock also contains abundant quartz and ferromagnesian minerals such as biotite or hornblende, commonly found in ancient mountain massifs.
- Aerolite — A meteorite composed mostly of silicate mineral substances (stony), sometimes exhibiting small metallic inclusions of iron and nickel. This category of celestial bodies that have fallen onto the Earth's surface is structurally divided into chondrites and achondrites, offering fundamental scientific data regarding the early composition of the solar system.
- Agiato — A technical musical term of manner or execution indication from Italian, meaning easily, comfortably, quietly, or at ease; it prescribes the performance of a composition or musical fragment in a moderate, relaxed tempo, free of structural haste.
- Agrogeologist — A female specialist in agrogeology; a researcher or specialist who studies the geological structure of soils, the mineralogical composition of parent rocks, and their influence on land fertility and plant development. She applies knowledge of geophysics and geochemistry to identify natural mineral resources useful for the structural improvement of degraded soils.
- Agrogeologist — A specialist in agrogeology; a researcher or engineer who studies the geological structure of soils, their genesis from parent rocks, and the influence of mineral composition on land fertility. This professional analyzes the geochemical and mineralogical properties of the terrestrial substratum to recommend natural amendments and optimal conservation methods for arable soils.
- Structure — A rare derived form or regional variant of the noun 'alcătuire'; the manner of organizing, structuring, or composing a whole from its constituent elements. The term is found in isolation within archaic literary texts or local dialects, retaining the abstract meaning of conformation or structural arrangement.
- Composition — The act of composing or forming and its result; the manner in which an object, a living organism, a text, or a theoretical system is structured, organized, or composed; composition, conformation, or internal structure. In a literary or philosophical register, the term refers to the cosmic or structural order of the world and nature's elements.
- Aleuritic — Pertaining to aleurite, regarding aleurite, or containing fine detrital elements with sizes intermediate between sand and clay. In structural geology, the term describes the texture or structure of sedimentary rocks where microscopic mineral particles (dust or silt) predominate, giving the rock a mealy feel and specific mechanical properties regarding permeability and cohesion.
- Moderately fast — A tempo and dynamic instruction originating from Italian, used in musical scores to dictate a fairly quick, lively, and light movement, but less rapid than that indicated by 'allegro'. As a noun, the term designates a musical piece or a movement of a larger composition (such as a symphony or a sonata) written in this graceful and animated pace.
- Fast — A tempo and dynamic instruction originating from Italian, used in musical scores to dictate a fast, cheerful, quick, and lively movement. As a noun, the term designates an independent musical piece or the first movement of a larger classical composition, such as a symphony, a concerto, or a sonata, performed at this brisk pace.
- Very fast — A composite tempo and dynamic instruction originating from Italian, used in musical scores to request a very fast and quick movement. The term combines the brisk 'allegro' base with the intensive modifier 'assai' (very / significantly), placing the execution pace just below 'presto' and giving the piece an impetuous, highly energetic character.
- Fast, but not too much — A composite tempo and dynamic instruction originating from Italian, used in musical scores to request a fast and lively movement but tempered, literally translated as 'fast, but not too much'. This compositional caveat instructs performers to maintain the bright, alert character of the 'allegro' pace while avoiding excessive speed that could jeopardize the clarity of melodic details, expressiveness, or technical precision of the passages.
- In the Hungarian style — A term of Italian origin (all'ungherese) used in musical scores to instruct performers to execute a passage in the Hungarian style, characterized by jerky rhythms, sudden accents, syncopations, and a passionate dynamic typical of traditional folk music or czardas dances. In international culinary arts, the phrase describes a way of preparing meat or sauces using a generous amount of paprika and sour cream.
- Allemande — A simplified phonetic variant or rare spelling sometimes used in old Romanian texts for 'allemande'; a traditional German dance with a moderate movement, in binary or quaternary meter, appearing in the 16th century, which became a fixed instrumental piece opening the classical Baroque suite.
- Allophane — An amorphous or poorly crystalline hydrated aluminum silicate mineral, often associated with the weathering of volcanic rocks and ash deposits in humid environments. This structural compound exhibits a variable chemical composition and a gelatinous or vitreous texture, holding significant importance in soil science due to its high cation exchange capacity and phosphate-fixing ability in andosols.
- Alteration — The act of altering or becoming altered and its result; a process of degradation, spoiling, decomposition, or distortion of the physical, chemical, or biological properties of a body or substance. In an abstract sense, it represents a falsification of the truth or a deep deterioration of relationships or emotional states.
- Aluminous — Containing aluminum or alumina in a considerable proportion; a characteristic attributed to soils, clays, rocks, or chemical compounds that present a high concentration of this metal.
- Alunite — A natural mineral from the class of hydrated sulfates, structurally composed of a basic aluminum and potassium sulfate, having the chemical formula KAl3(SO4)2(OH)6. Historically called alumstone, it occurs as granular, fibrous masses or white, grayish, or reddish rhombohedral crystals, used on an industrial scale for extracting alum and aluminum.
- Alunite — A formal variant or structural feminine adaptation of the term 'alunit', sometimes used in older technical literature or mining jargon to denote alumstone; a sedimentary or hydrothermal rock composed predominantly of this mineral. This compound represents an important natural source of hydrated aluminum and potassium sulfates, processed industrially for its astringent qualities.
- Alvanite — A rare natural mineral from the hydrated vanadate class, structurally composed of a hydrated aluminum and zinc vanadate, having the chemical formula Al3(VO4)(OH)6·2H2O or related. It occurs as microcrystalline aggregates, crusts, or rosettes of a pinkish-yellow, white, or grayish color, found in the oxidation zones of uranium and vanadium deposits.
