对位于犹他州大盐湖海岸的典型蓝绿色定殖隐杆藻Aphanothece Packardii沿着的生物层进行了详细的调查，结果表明该藻生长具有明显的形态分带性。后者由四个区域组成，从湖到陆地：近平行的花彩山脊;舌状花彩山脊;复合环和平顶土丘;小孤立的土丘。通过生物层的详细横截面表明，形态带只是再现并经常夸大了在坚硬的泥质和鲕粒砂中侵蚀的底层地形。得出的结论是，这些群体藻类没有自己的特征性生长模式，但已开发的几种类型的积极领域分开的侵蚀渠道系统的走向，在直角的海岸线。
The detailed investigation of a typical biostrome of the blue-green colonial alga Aphanothece Packardii along the shore of the Great Salt Lake, at Promontory Point, Utah, has shown a distinct morphological zona-tion of the algal growth. The latter consists of four zones from the lake to the land: subparallel festooned ridges; tonguelike festooned ridges; composite rings and flat-topped mounds; small isolated mounds. Detailed cross sections through the biostrome have shown that the morphological zones merely reproduce and frequently exaggerate an underlying topography eroded in firm argillaceous and oolitic sands. The conclusion is reached that these colonial algae have no characteristic growth pattern of their own but have developed on several types of positive areas separating a system of erosional channels trending at right angles to the shore line.
