The secondary laminae contain basal cells which attach via hemidesmosomes to the basement membrane.
次生薄片包含基底细胞，这些基底细胞通过半脂质体附着在基底膜上。

Lacustrine laminae are mainly deposited in lake water with obvious layering. Such factors as temperature, salinity and depth control the water layering.
湖泊纹泥和湖相页岩主要沉积于湖水明显分层的条件下，湖水的分层受气候、盐度、水体深度等多方面的控制。
