Palaios, v. 27, p. 252-273. This work proposed that vertical circulation of ocean water led to oxygenation of the deep ocean shortly before the end of the Proterozoic time, which may also have contributed to the rise in biodiversity in early Cambrian time.

These results highlight the biological viability of fluvial-lacustrine environments in the post-Noachian history of Mars.

Sedimentary rocks can provide clues that allow past environmental conditions to be reconstructed.

Though the accretion process is commonly regarded to result from the sediment trapping or precipitation-inducing activities of microbial mats, only rarely is evidence of this process preserved in Precambrian stromatolites.

Application of this approach has shown that stromatolites were originally formed largely through in situ precipitation of laminae during Archean and older Proterozoic times, but that younger Proterozoic stromatolites grew largely through the accretion of carbonate sediments, most likely through the physical process of microbial trapping and binding. 2006 - Understanding Earth 4th ed., Press and Siever, Grotzinger, Jordan Fall 2007 - Physical Geology, 2nd Canadian ed., Plummer, McGeary, Carlson, Eyles, Eyles Geol/Geog 220 … ), Presidential Young Investigator Award of the National Science Foundation (1990), Co-evolution of Earth's early environment and biosphere, Learn how and when to remove these template messages, Learn how and when to remove this template message, Virginia Polytechnic Institute and State University, http://zipcodemars.jpl.nasa.gov/bio-contribution-missions.cfm?bid=162&cid=157&pid=158&page=&country_id=0&state_id=0, https://en.wikipedia.org/w/index.php?title=John_P._Grotzinger&oldid=987010001, Massachusetts Institute of Technology faculty, California Institute of Technology faculty, Members of the United States National Academy of Sciences, BLP articles lacking sources from March 2017, Articles lacking in-text citations from March 2017, Articles with a promotional tone from March 2017, Articles with multiple maintenance issues, Wikipedia articles with BIBSYS identifiers, Wikipedia articles with CANTIC identifiers, Wikipedia articles with ORCID identifiers, Wikipedia articles with SUDOC identifiers, Wikipedia articles with WORLDCATID identifiers, Creative Commons Attribution-ShareAlike License, This page was last edited on 4 November 2020, at 08:56.
