"flints"是名詞"flint"的複數形式,指一種主要由隱晶質二氧化矽構成的堅硬沉積岩。根據地質學定義,其形成過程與遠古海洋中矽質生物遺骸沉積相關,莫氏硬度可達7,斷面呈貝殼狀。在考古學領域,燧石作為舊石器時代人類制造工具的核心材料,被廣泛用于制作石刀、箭镞和取火工具,英國約克郡考古遺址中曾出土距今30萬年的燧石手斧。
現代應用中,燧石仍用于高端打火機火石制造,其與鋼鐵撞擊産生火花的特性被瑞士品牌IMCO持續沿用。在建築材料領域,英國肯特郡傳統建築中保留了大量燧石砌牆工藝,這種建築材料具有抗風化特性。地質學家特别關注燧石結核的形成機制,美國地質學會期刊最新研究指出,其球狀結構可能與矽質凝膠的周期性沉積有關。
單詞“flints”是“flint”的複數形式,其含義和用法如下:
