Magnified 400x, grains of sand from a beach in Maui, Hawaii, reveal a stunning diversity of shapes, colors, and textures. Unlike the uniform appearance seen with the naked eye, each grain is unique, reflecting the complex geological history of the island. Some grains are clear or translucent, likely composed of quartz, while others may be pink, red, or black, indicating the presence of coral fragments, volcanic basalt, or minerals like garnet. The sand grains are often irregular in shape, with smooth, rounded edges from continuous weathering by waves and wind. Some may appear more angular, particularly those formed from recently broken coral or volcanic rock. At this magnification, you can also see tiny inclusions, striations, and surface pitting on the grains, all of which contribute to the rich, detailed mosaic of colors and textures that characterize Maui's beaches. This microscopic view highlights the beauty and complexity of sand, turning each grain into a miniature geological specimen.
