佛曇层在福建省境內仅分布于閩南漳浦沿海一带,它复盖在花崗岩之上。其岩相頗为复杂,最清晰的剖面见于前湖村的海滨和东吳村的赤湖溪边。在前湖村的剖面中(图1),一共可分为五层:第一层由棕黄色细砂、中砂組成,厚約2米,砂粒多为石英,磨圆度中等,其上为現代风砂层(厚約20厘米)所复盖。风砂层也多由細小的石英粒所組成,并夹有少量的細小黑云母片,石英粒暗淡无光,全层呈淡黄色,可与第一层截然分开。第二层由乳白色细砂、中砂組成,厚約2.5米,貭很純,全为石英貭,含有较多黑色矿物,井有交錯层存在。第三层为黄紅色粉砂、细砂层,厚約14厘米。第四层为灰黑色粘土层,夹有30—35％左右的細砂,厚約40—110厘米,細砂有
Buddha Tan in Fujian Province only distributed in the southern Fujian Zhangpu coastal area, which covered in granite above. Its lithofacies are quite complex, with the sharpest sections seen at the waterfront of the former Lake Village and at the Chek Lakeside in Soochow Village. In the former Lake Village profile (Figure 1), a total of five layers can be divided into: the first layer of sand and sand by the fine sand, composed of sand, about 2 meters thick, mostly sand quartz, roundness on the medium, which is modern Wind sand layer (about 20 cm thick) covered. The sand layer is also composed of fine quartz grains, with a small amount of tiny black mica. The quartz grains are dull and yellow, and can be completely separated from the first layer. The second layer of milky white sand, composed of sand, about 2.5 meters thick, 貭 very pure, all quartz 貭, containing more black minerals, well there is staggered layer exists. The third layer is yellow-red silt, fine sand layer, about 14 cm thick. The fourth layer of gray-black clay layer, sandwiched between about 30-35% of fine sand, about 40-110 cm thick, fine sand there
