柱状分叉迭层石产于美国蒙大拿州国家冰河公园贝尔特超群的Altyn石灰岩(约13亿年)、Siyeh石灰岩(约11亿年)及Snowslip组(约11亿年)内。本文列举了影响该迭层石的分叉型式的四个自然因素:1.迭层体生长面上的非生物碎屑堆积,2.迭层石柱体的间距,3.迭层石生物礁的生长形态,4.环境条件的变化程度。虽然构成该迭层石的微生物群的生物组成亦对分叉型式有某种影响,但上述四个自然因素在控制该迭层石分叉型式方面起了重要作用。因此,依据柱状分叉迭层石形态对地层年代和古环境进行解释时须考虑上述因素的作用。
Columnar bifurcated laminated stone produced in the United States, Montana National Glacier Belt superb Altyn limestone (about 1.3 billion years), Siyeh limestone (about 1.1 billion years) and Snowslip group (about 1.1 billion years). This article lists four natural factors that affect the bifurcation pattern of the laminated stone: 1. Stacking of non-biological debris on the growing face of the laminate, 2. Spacing of stacked stone pillars, 3. Interlaminar reef reef Growth morphology, 4. Environmental conditions change degree. Although the biological composition of the microorganisms that make up the laminated stone also has some effect on the bifurcated pattern, the four natural factors described above play an important role in controlling the pattern of bifurcated stone bifurcation. Therefore, the role of the above factors must be considered when interpreting the age and paleoenvironment of the strata according to the shape of the columnar bifurcated stratum.
