Vast laminated diatom mat deposits from the west low-latitude Pacific Ocean in the last glacial period
Diatoms are one of the predominant contributors to global carbon fixation by accounting for over 40% of total oceanic primary production and dominate export production. They play a significant role in marine biogeochemistry cycle. The diatom mat deposits are results of vast diatoms bloom. By analysi...
