千層石，也稱積層巖，屬于海相沉積的結晶白云巖，石質堅硬致密，外表有很薄的風化層，比較軟；石上紋理清晰，多呈凹凸、平直狀，具有一定的韻律，線條流暢時有波折、起伏，偶成圖案；顏色呈灰黑、灰白、灰、棕相間，其棕色稍顯突，色澤與紋理比較協調，顯得自然、光潔；造型奇特，變化多端，多有山形、臺洞形等自然景觀，亦有寶塔形、立柱形及人物、動物等，既有具象又有抽象，神韻秀麗靜美、淡雅端莊。小者2～3厘米，大者高1米以上。千層石可用于點綴園林、庭院，或作廳堂供石，也可制作盆景，具有較高的觀賞價值。
    千層石形成于距今12～13億年的晚元古代薊縣紀，當時的砂巖、硅質巖、白云巖、鐵、錳等物質海相沉積后，經地質構造運動，滄桑變遷，而成為如今的千層石。
