Summary
| Description |
Русский: Для изучения горных пород используют специальные препараты — шлифы. Это тонкие (0,03 мм) пластинки горных пород, наклеенные на предметное стекло и закрытые покровным. На фото можно увидеть шлиф базальта в скрещенных николях. Базальтами называют изверженные горные породы основного состава, что отражается в минеральном составе породы и её микроструктуре. Как можно видеть на фото, порода почти полностью сложена мельчайшими кристаллами полевого шпата (светло-серые) и пироксена (цветные), образовавшимися при застывании лавы. Однако можно наблюдать и крупные кристаллы пироксена (внизу справа, цветной) и плагиоклазов (округлые в центре и сверху), которые образовались в магме ещё задолго до её извержения. Панорамное изображение получено склейкой 45 отдельных изображений, ширина поля зрения 25 мм English: To study rocks using special preparations - thin sections. These are thin (0.03 mm) rock plates glued to a glass slide and covered with a coverslip. On the photo you can see the basalt thin section in crossed nicols. Basalts are calledmafic extrusive igneous rock with specific mineral composition and microstructure. As can be seen in the photo, the rock is almost completely composed of plagioclase microlites (light gray) and clynopyroxene (colored) formed during solidification of the lava. However, one can observe large crystals of clynopyroxene (bottom right, colored) and plagioclases (rounded grains in the center and top), which formed in magma long before its eruption. This panoramic image was obtained by gluing together 45 images, FOV 25 mm. |
