Description:
The Galapagos mounds sea-floor hydrothermal system is at least 300,000 years old and once produced manganese-poor sediments, which nearly blanketed the area of the present mounds field. Present-day mound deposits are limited manganese-rich exposures, suggesting that the system has changed from rock-to water-dominated and has diminished in intensity with time.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Natland, J H -- Rosendahl, B -- Hekinian, R -- Dmitriev, Y -- Fodor, R V -- Goll, R M -- Hoffert, M -- Humphris, S E -- Mattey, D P -- Petersen, N -- Roggenthen, W -- Schrader, E L -- Srivastava, R K -- Warren, N -- New York, N.Y. -- Science. 1979 May 11;204(4393):613-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17839484" target="_blank"〉PubMed〈/a〉
