现代断陷湖盆沉积考察表明，并非湖盆边缘处处发育粗粒沉积相，粗粒沉积体系仪仅发育在主河口附近。

The reviews of modern half graben lakes show that coarse depositional facies do not developed everywhere along the lake margin, but only at the main river mouths.

在陆相断陷湖盆陡坡带，控盆断裂的剧烈活动导致在相对较短时期内形成盆地的快速沉降，与湖盆边缘地形形成巨大高差。

In a half-graben, the early-stage movement of the basin-controlling fault results in a great height difference along the lake margin.
