АКТ Наука - Geology

a site where large quantities of rock, stone, or minerals are extracted from the Earth's crust for industrial use or construction purposes

карьер

a fracture or zone of fractures between two blocks of rock, along which there has been significant displacement due to tectonic forces

разлом

solid rock beneath surface materials, forming the Earth's crust foundation

основная порода

a type of fine-grained sedimentary rock made from compacted clay or mud particles, known for its ability to split into thin layers

сланец

a type of dark, fine-grained igneous rock formed from cooled lava, characterized by its dense composition and typically dark gray to black color

базальт

a durable and visually appealing natural rock used for countertops, flooring, and other architectural applications

определяющий ископаемое

(geology) the injection of magma into existing rock formations underground

related to rocks transformed by intense heat, pressure, or chemical processes, altering their mineral composition and texture

метаморфный

relating to the movement and arrangement of the Earth's crust

тектонический

to extract metal from its ore by heating and melting it in a furnace

the byproduct of smelting ore that forms a glass-like material, often found as a residue in mining and metalworking activities

шлака

the period of time from about 252 to 66 million years ago, characterized by the dominance of dinosaurs and the gradual breakup of the supercontinent Pangaea

мезозой

a mineral with a greenish hue, commonly found in igneous rocks like basalt and peridotite, known for its high magnesium and iron content

оливин

a group of minerals found in igneous and metamorphic rocks, typically dark in color and composed of silica, magnesium, and iron

пироксен

a group of minerals that are the most abundant components in the Earth's crust, known for their hardness and varied colors, often used in ceramics and glassmaking

польевой шпат

a type of rock formed from clay minerals that have been compressed and hardened over time, creating a dense and often smooth-textured material

аргиллит

a scientist who studies the Earth's structure, composition, processes, and history, including rocks, minerals, fossils, and geological phenomena

геолог

a scientist who specializes in the study of earthquakes and seismic waves, investigating their causes, effects, and patterns

сейсмолог

the point on the surface of the earth vertically above the focus of an earthquake where its effects are felt most strongly

эпицентр

an earthquake caused by underground movement or volcanic activity

землетрясение

a small or slight earthquake

тремор

the sudden outburst of lava and steam from a volcanic mountain

эрепция

a type of broad, gently sloping volcano formed by the eruption of low-viscosity basaltic lava

щитовой вулкан

a branch of geology that focuses on the study of volcanoes, volcanic activity, and related phenomena

вулканология

liquid or semi-liquid rock that exists under the earth's surface with an extremely hot temperature

магма

a large, basin-shaped volcanic crater formed by the collapse of a volcano after a massive eruption

кальдера

a tough type of rock that starts as sandstone but changes under intense heat and pressure underground, becoming very hard and durable

кварцит

particles of rock, minerals, or organic materials that have been transported by wind, water, or ice, and deposited in layers on the Earth's surface

осадок

a visible exposure of rock or geological strata at the Earth's surface, often occurring on hillsides, cliffs, or other elevated areas, providing insight into the underlying geological structure

выступ

connected with or produced by the heat inside the earth

геотермальный

a large, bowl-shaped depression or low-lying area on the Earth's surface, typically surrounded by higher landforms and often filled with sedimentary deposits

бассейн

the thick, buoyant part of the Earth's crust that forms the continents, composed mainly of granitic rocks and less dense than oceanic crust

континентальная кора

a landmass that existed in the geological past

палеоконтинент

a geological process where one tectonic plate moves under another and sinks into the Earth's mantle

субдукция

the region of the Earth's interior, lying beneath the crust and extending to the outer core, composed of solid rock that can deform and flow over geological time scales

мантия

a hard gray or white rock that contains calcium and is used for making cement or as a building material

известняк

a soft, white clay mineral formed from the weathering of aluminum-rich rocks, used widely in ceramics, paper production, and as a filler in some medications

каолин
