潍河-弥河三角洲是一个由多条河流共同塑造的三角洲。前三角洲黏土质粉砂是各河流共同贡献的结果;每条河口之外形成各自的三角洲前缘,主要由极细砂组成;河口间湾沉积物是两条相邻河流共同塑造的,主要为黏土质粉砂。由于河口位置的侧向摆动,三角洲前缘极细砂和河口间湾黏土质粉砂会交替出现。7000 aB.P.以来向海进积20~55 km,在海岸附近三角州沉积物厚度超过20 m。 Wei River - Mi River Delta is a delta shaped by multiple rivers together. The former delta clay silt is the result of the common contribution of rivers. Each delta forms the front of the delta, which is composed of extremely fine sand. The estuary bay sediments are co-shaped by two adjacent rivers, mainly Clay silt. Due to the lateral swinging of the estuary, very fine sand in the delta front and inter-estuary clay clay will alternately appear. 7000 aB.P. has been deposited 20 to 55 km above sea level, and sediments in the delta state near the coast have exceeded 20 m in thickness.
