Abstract
Hot spring cyanobacterial mats from Yellowstone National Park, U.S.A. and the Orakei Korako thermal area, New Zealand have been found to contain suites of monomethyl alkanes, compounds frequently reported in cultured and natural populations of cyanobacteria. The complete range of possible structural isomers for mid-chain branching for C17/C18 and C16/C18 alkanes occurs in the two mats, respectively. Several C19 dimethyl and C20 multibranched alkanes were also observed as major hydrocarbons of the Orakei Korako mat. The recognition of series of mid-chain branched alkanes in modern cyanobacterial mats suggests that their occurrence in ancient sediments may reflect direct biogenic contributions, rather than formation by diagenetic processes.
