叠层石是以蓝藻为主的微生物在生长和代谢活动过程中吸收沉淀矿物质或捕获矿物颗粒,形成具有纹层的生物沉积构造。蓝藻是一种可进行光合作用的原核生物,生活在阳光充足的浅水中,具有明显趋光性。当水深超过蓝藻生活的适宜水深时,为了吸收更充足的阳光,蓝藻会迅速向上生长,此时形成的就是上凸拱形的叠层石;随后,水深逐渐向蓝藻生活适宜水深变浅时,蓝藻处在接近最佳生活环境中,就会逐渐停止向上生长,转而在这一水深向周围大量繁殖生长,此时形成的叠层石就
Stratosphere is a cyanobacteria-based microorganism that absorbs sediment minerals or traps mineral particles during growth and metabolic activity to form a biodeposited structure with laminae. Cyanobacteria are photosynthetic prokaryotes that live in sunny, shallow waters with significant phototaxis. When the depth of water more than the appropriate depth of life of blue algae, in order to absorb more sunshine, the rapid growth of cyanobacteria will be formed at this time is the convex arched stratigraphic; then gradually deepen the depth of water to the cyanobacteria water depth, Cyanobacteria near the best living environment, it will gradually stop growing up, in turn to a large number of this water around the growth and reproduction, the formation of the laminated stone on
