辽东和辽北的黄土状沉积物称为棕黄土,以区别于典型黄土,分布于高出现代河床20～30米的岗台地上。根据产状、颗粒组成和矿物成分。它们可能是风成的。昌图县的棕黄土可能来自内蒙沙地,大连附近的黄土可能来自北面的海域,其中含有有孔虫,宽甸盆地中的棕黄土则以大气尘降落的形式形成的。各地棕黄土中的矿物组成也不同,缓效钾的含量与粘粒含量成正相关,表明伊利石是其中的主要组成成分。
The loess-like sediments in Liaodong and northern Liaoning are called brown loess and are distinguished from typical loess and are distributed in the Kongtai land 20 to 30 meters above the modern riverbed. Depending on the shape, particle composition and mineral composition. They may be successful. The brown loess in Changtu County may come from the Inner Mongolia sandy land. The loess near Dalian may come from the north sea, which contains foraminifera. The brown loess in the Kuandian Basin is formed in the form of atmospheric dustfall. The mineral composition of brown loess varies from place to place. The content of slow-acting potassium is positively correlated with the clay content, indicating that illite is the major component.
