“…Upward growth is restricted by sub-aerial exposure (Burne and Moore, 1993). The oldest 101 parts of the thrombolite reef have been dated at 1950 years BP (Moore and Burne 1994), and 102 Lake Clifton is underlain by sediments of marine origin, the youngest of which are dated at 103 4,670-3,890 years BP (Coshell and Rosen, 1994). 104…”

“…Radiocarbon dating indicates that the age of the thrombolites in Lake Clifton is 37 approximately 1950 years BP to modern (Moore and Burne 1994). They were probably 38 formed after the isolation of the lake from the sea, which occurred between 4,670 and 3,890 39 years BP (Coshell and Rosen 1994), by precipitation of aragonite by microbial activity 40 .…”

“…이는 신생대의 해수에 포함된 탄산칼슘의 농 도가 너무 낮아 시아노박테리아의 표면이 석회화되기 는 어려운 반면, 규조류 등의 굵은 입자를 잘 붙잡는 미생물들이 미생물암을 만드는데 기여하기 시작했기 때문으로 생각된다 (Riding, 2011b). 육성 환경에서 미 생물암은 캐나다의 파빌리온 호수(Pavilion Lake), 켈 리 호수(Kelly Lake), 오스트레일리아의 클리프턴 호 수(Lake Clifton) 등 염도가 높은 호수에서도 발견된 다(e.g., Moore and Burne, 1994;Ferris et al, 1997;Laval et al, 2000). 현생 미생물암에 대한 연 구 결과 다양한 종류의 미생물이 기존 예상보다 훨씬 더 복잡한 기작을 거쳐 미생물암을 생성하며, 이들이 기후 등 다양한 환경 변화를 기록하고 있음이 밝혀졌 다(e.g., Last et al, 2010;Omelon et al, 2013;Burne et al, 2014;Russell et al, 2014).…”

“…미생물암 에 대한 연구는 Kalkowsky(1908)가 트라이아스기 퇴 적층에서 얇은 엽층으로 이루어지고 위로 볼록한 퇴 적체를 인지하고, 이에 대해 스트로마톨라이트 (stromatolite)라는 용어를 제안하면서 이러한 구조가 미생물에 의해 만들어졌을 것이라고 제시한 데에서 시작되었다 (Paul and Peryt, 2000). 이후 오스트레일 리아의 샤크만(Shark Bay)과 바하마 등에서 현생 미 생물암이 발견되어 이에 대한 연구가 오늘날까지 지 속적으로 이루어지고 있다 (Dravis, 1983;Dill et al, 1986;Moore and Burne, 1994;Reid et al, 1995Reid et al, , 2003Ferris et al, 1997;Feldmann and McKenzie, 1998;Laval et al, 2000;Andres and Reid, 2006;Jahnert and Collins, 2011). 미생물암을 형성하는 미 생물들은 선캄브리아 시대에는 광합성을 통해 다량의 산소를 생성하여 오늘날과 같은 대기를 조성하는 데 크게 기여했으며, 또한 현생 산호초와 유사한 대규모 생물초(biogenic reef)를 형성하는 등 탄산염암의 퇴적 작용에도 깊이 관여하였다 (Riding, 2000;James and Wood, 2010).…”

Microbialites are defined as rocks formed by microbial organisms. After their first appearance around 3.5 billion years ago, microbialites occur in various depositional environments throughout geological periods. Microbial organisms form microbialites by trapping and binding detrital sediments and/ or precipitating carbonate cements, resulting in formation of various microstructures and mesostructures. Four major types of microbialites are distinguished based on their mesostructures: stromatolite, thrombolite, dendrolite, and leiolite. In the geological records, occurrences of microbialites are influenced by calcium carbonate saturation of seawater and interaction of microbialites with metazoans. Stromatolites mainly flourished during the Precambrian, and diminished as level of atmospheric carbon dioxide declined. On the other hand, thrombolites, mainly formed by calcified microbes, began to flourish from the Neoproterozoic. As metazoans diversified in the Phanerozoic, proportion of the microbialites within sedimentary record declined. Since then, microbialites only occasionally flourished during the Phanerozoic, such as shortly after mass-extinction events. In the Korean Peninsula, microbialites occur in the Neoproterozoic Sangwon System, the Early Paleozoic Joseon Supergroup, and the Cretaceous Gyeongsang Supergroup, which form different shapes according to their age and depositional environments. By performing detailed studies on these Korean microbialites, it is possible to understand how microbes affected geological records and sedimentary environments, as well as their interaction with other organisms.

“…The translation of this phenomenon is a shift in microbial communities from a phototrophic-dominated (filamentous cyanobacteria Scytonema) to a more dheterotrophicT-dominated community (in this case, coccoid communities). It is important to point out that thrombolite can also be formed by filamentous bacteria (e.g., Moore and Burne, 1994). In the simulation, stromatolitic parts of the build-up are represented by a stable community (high stability distance), with a tendency to grow laterally (horizontal CA), and especially a light-driven community (high motion index, ballistic motion).…”

Stromatolites are examples of an iterative system involving radiate accretive growth of microbial mats, biofilm and/or minerals that result from interaction between intrinsic and extrinsic factors, which progressively shape the final morphology. These interactions can neither be easily described by simple mathematical equations, nor by simple physical laws or chemical reactions. Therefore, a holistic approach that will reduce the system to a set of variables (which are combinations of natural variables) is proposed in order to create virtual morphologies which will be compared with their natural counterparts. The combination of both Diffusion Limited Aggregation (DLA) and cellular automata (CA) allows the exploration of the stromatolite morphological space and a representation of the intrinsic and extrinsic factors responsible for natural stromatolite morphogenesis. The holistic approach provides a translation in simple parameters of (1) the way that energy, nutrients and sedimentary particles reach the active surface of a future build-up, (2) how these elements are distributed and used in order to create morphology, and (3) how simple environmental parameters, such as sedimentation, can disturb morphogenesis. In addition, most Precambrian stromatolite morphologies that are impossible to produce with numerical modeling such as the Kardar-Parisi-Zhang (KPZ) equation can be simulated with the DLA-CA model and this, with a minimum set of variables.
