通过对青岛近海1561km的高分辨率浅地层测量剖面解译,在多条剖面中发现研究区存在多期发育的古河道,虽然保存较完整的地层不多,但大部分河流亚相地层被保存。测年资料表明,这些河流多形成在37000～11000a之间,河流床底最大埋深(海底起算)约-32m,一般在-20～-28m,最大单个河面宽约1500m。根据现在所见河道的轮廓形态,可分为六种类型:即发育有滩心洲的河道、平底河道、不对称河道、连续多期发育的河道、窄陡型河道和对称型河道。并对河流的形成机理和古地理特征作了初步分析。
Through the interpretation of the high-resolution shallow stratigraphic cross section of 1561km offshore Qingdao, the ancient rivers with multiple developmental stages in the study area are found in many sections, and most of the river subfacies are preserved although less well-preserved strata . The dating data show that these rivers are mostly formed between 37000 and 11000a. The maximum bed depth of the river bed (about seabed) is about -32m, generally between -20 and -28m, and the largest single river is about 1500m wide. According to the contour shapes of the rivers we can see now, there are six types of rivers, namely, the river bank with flattened heart, flat river, asymmetrical river, continuous multi-period river, narrow steep river and symmetrical river. The formation mechanism and palaeogeographical features of rivers were also analyzed.
