Polarised LM of a thin section of gabbro rock
Gabbro. Polarised light micrograph of a thin section of gabbro, an igneous rock. Gabbro is coarse-grained, containing the minerals olivine and plagioclase feldspar. Olivine is recognised here by its irregular shaped crystals, with randomly oriented fractures. Plagioclase feldspar forms lath- shaped crystals. Specimen of rock obtained from the Bushveld range in the Transvaal, South Africa. Magnification: x8 at 6x7cm size

EDITORS COMMENTS
This print showcases a polarised light micrograph of a thin section of gabbro rock, an intriguing igneous rock. Gabbro is known for its coarse-grained texture and within this sample, we can observe the presence of two prominent minerals - olivine and plagioclase feldspar. The irregularly shaped crystals with randomly oriented fractures represent the mineral olivine. Its unique characteristics make it easily recognizable in this image. On the other hand, plagioclase feldspar forms lath-shaped crystals, adding another layer of complexity to this fascinating rock specimen. Obtained from the Bushveld range in Transvaal, South Africa, this particular gabbro sample offers valuable insights into Earth's geological history. The magnification level used for capturing this image was x8 at 6x7cm size, allowing us to appreciate even the finest details present within the thin section. As we delve into geology and earth science through images like these, we gain a deeper understanding of our planet's composition and evolution over time. Science Photo Library has once again provided us with an awe-inspiring glimpse into nature's wonders through their exceptional photography skills.
