Siliceous

Siliceous describes something composed primarily of, containing, or resembling silica (silicon dioxide, SiO₂), a hard, unreactive mineral commonly found in sand, quartz, and flint. This term often applies to geological formations, biological structures, or manufactured materials where silica plays a crucial role in structure, composition, or properties. siliceous materials are typically resistant to chemical weathering and high temperatures, contributing to their durability and wide range of applications, from construction to biological systems.

Siliceous meaning with examples

• The paleontologist carefully examined the siliceous skeletons of the diatoms under a microscope. These microscopic algae possess intricate, glass-like structures made of silica that provide essential protective properties and aid in their survival. This incredible silica-rich design shows the power of evolution.
• During the excavation, archaeologists found numerous siliceous artifacts, including finely crafted arrowheads and tools. Their use of siliceous materials like flint revealed their advanced understanding of stone tool technology. This finding showed the high level of craftsmanship within the ancient civilization.
• The building's exterior was composed of a siliceous concrete reinforced with silica fibers. This choice provided exceptional resistance to the region's harsh weather and contributed to the building's longevity. The durability and strength of the silica in the building are phenomenal.
• The beaches were covered in a fine, siliceous sand composed primarily of quartz grains. The children played on the soft, white sand with glee, enjoying the contrast of textures between the sand and the water. siliceous sand feels great on your feet.
• Microscopic examination of the rock revealed its siliceous composition, revealing the presence of quartz and other silica-rich minerals. Geologists analyzed these materials to identify the rock's formation and the geological history of the region. The composition showed a wide range of silica formations.
