摘　　要：为探究华北唐宋著名古瓷窑兴起的自然条件及其实质,收集了54个华北唐宋著名古瓷窑址,综合煤田地质学、地理学和考古学等展开探讨。空间分析揭示这些古瓷窑址均坐落在石炭纪—二叠纪煤系地层边缘出露区,整体呈现“东密西疏”的分布格局。煤系地层出露不仅暴露了煤而且暴露了煤的共伴生矿产——煤系高岭岩;此煤系高岭岩经历百万年级的自然暴露,在空气和水的持续作用下发生了地球化学风化作用,逐渐形成含水凝胶态的高龄泥。研究显示,煤系地层天然出露为泛华北唐宋古瓷窑兴起提供了自然条件,实质是利用天然可塑性的高龄泥直接制胎。In order to investigate the relationship between the emergence of famous ancient porcelain kiln sites and the outcropping of coal-bearing strata in North China during the Tang and Song dynasties.We collected data on 54 famous ancient porcelain kiln sites of the Tang and Song dynasties in North china,and conduct research by coal geology,geography,and archaeology.Spatial analysis shows that these ancient porcelain kiln sites are located within a certain range or even within the outcrop point at the edge of the Carboniferous-Permian coal measures.The overall distribution pattern is“dense in the east and sparse in the west”.After millions of years of natural weathering,the exposed coal-bearing kaolinite gradually depolymerized.It was dissolved and leached under the joint action of sulfuric acid,humic acid and carbonic acid,etc,and finally forms gel state kaolin clay with rich water.Weathered porcelain clay is easily accessible to the ancient people after being exposed to the surface.The research shows that the craftsmen in the famous ancient porcelain kiln sites of the Tang and Song Dynasties in North China not only used kaolinite exposed in coal seams,but also used naturally weathered kaolin clay directly.
