Geomicrobiological Properties and Processes of Travertine / Springer Geology (PDF)

Takashima is an associate professor at the School of Education (earth science) at Saga University. Her specialties are carbonate sedimentology and geomicrobiology. Her background study was in the sedimentology of microfossils in limestone and deep-sea coral mounds, and she has extended her research topics to hydrothermal iron deposits resembling Precambrian banded iron formations (BIFs). Recently, she investigated the interaction of spring water, mineral precipitates, and microbes in domestic and foreign hydrothermal environments with sedimentological, geochemical, and biological approaches to elucidate the processes of Precambrian deposits. With the co-authors of this book, she has published articles related to the process of daily lamination in travertines contributed by cyanobacterial metabolism and laminations in iron-rich travertines induced by iron-oxidizing bacteria.



Dr. Fumito Shiraishi is an assistant professor in the Department of Earth and Planetary Systems Science, Graduate School of Science, Hiroshima University. He received his bachelor's and master's degrees in geology at Hiroshima University, studying Japanese Mesozoic limestones using paleontological and geochemical techniques. He received a Dr. rer. nat. under the supervision of Professor Gernot Arp at the University of Göttingen (Germany) in 2008, studying German recent tufa deposits, using geochemical and microbiological techniques. Thereafter, he worked as a postdoctoral fellow at Hiroshima University, then as a Japan Society for the Promotion of Science (JSPS) research fellow at Kyushu University, and continued studying recent calcified biofilms in these positions. Since November 2011, he has been an assistant professor at Hiroshima University. His present research also focuses on non-carbonatemicrobial deposits (including phosphate iron oxides, manganese oxides, and siliciclastics) to elucidate Earth and life evolutions. He has published several papers in established science journals, and he has co-authored a book on travertine, GEOBIOCAL Atlas (Brazil Publishing 2016).
