对现代砂泥质潮坪研究,不仅有益于弄清潮汐沉积作用,而且为探讨古潮坪沉积,寻找有关矿产提供依据。近年来我们对弶港潮坪调查研究表明,该潮坪是以古长江和旧黄河组成的三角洲为基础,并在两股强潮流以弶港为顶点辐聚辐散控制下所形成的滩面宽阔,潮沟发育,向海开敞的潮坪。本文着重探讨潮坪不同地貌单元沉积物的特点和相标志。不妥之处,望祈指正。
The research on modern sand-muddy tidal flat not only helps to find out the tidal sedimentation, but also provides a basis for exploring the deposition of ancient tidal flat and finding relevant minerals. In recent years, we have investigated and studied the tidal flat in Langfang, which shows that the tidal flat is based on the delta formed by the ancient Yangtze River and the old Yellow River and is formed under the convergence and divergence control of two strong tidal currents Broad, tidal ditch development, open to the sea tidal flat. This article focuses on the characteristics and phase markers of sediments of different landforms in tidal flat. Improper, hope pray.
