Microbial mat and film on hot-spring travertines were studied for understanding developmental processes of stromatolites that had been widely debeloped in ancient oceans. Togetherwith a post-doc reseacher, I performed continuous observation of sedimentary texture and water chemistry. Genetic analyses were also done for the specimens collected from the travertine surfaces. The results of these analyses indicated that the laminated textures were basically daily and refrected from metabolic cycle of photosynthesic bacteria including cyanobacteria. Results from study localities (e.g., Nagayu hot-sprng in Ohita Prefecture and Myoken hot-spring in Kagoshima Prefecture) were published in reseach papers including three international journal papers. Study in Nagayu hot-spring was especially important in terms with similality with the ancient stromatolites.

为了解古海洋中广泛发育的基质层的发育过程，对温泉基质上的微生物垫和膜进行了研究。我和一位博士后研究员一起，对沉积结构和水化学进行了连续观察。对采集自南极大陆表面的标本也进行了遗传分析。分析结果表明，该纹层结构基本上是日性的，是光合细菌（包括蓝藻）代谢循环的产物。研究地点的结果（例如，日本大分县长汤温泉和鹿儿岛县妙手轩温泉的研究论文发表在国际期刊论文3篇。在与古叠层石的相似性方面，长游温泉的研究尤其重要。
