一、前言泻湖沉积是海陆过渡带中分布广泛的一种沉积类型,正确识别地层中的泻湖相沉积不仅对于古地貌、古岸线和海面升降等古地理研究具有重要意义,而且在油气、岩盐等矿产的勘探上亦具实际价值。为探讨泻湖沉积物的微体古生物标志,我们对山东省荣成地区若干泻湖底质表层中活介形虫进行了调查,以期找出其分布规律,为“将今论古”用介
I. Introduction Lagoon sedimentation is a widely distributed sedimentary type in the transitional zone of the sea and land. The correct identification of the lacustrine sediments in the strata is of great significance not only for palaeogeography, ancient coastline and sea surface lift, but also for petroleum, rock salt Other mineral exploration is also of practical value. In order to investigate the micro-organism paleontological signs of lagoon sediments, we investigated the surface ostracods of several lagoon sediments in Rongcheng area of Shandong Province in order to find out the distribution rules of them.
