Algae are internationally divided into sixteen phyla,
but China adapted the classification of only fourteen phyla during the
national algae meetin gheld in Qingdao in 1964. Coccoliths belong to Coccolithophyceae
of Chrysophuyta. They are a primary producer and a main osuce of abyssal
carbonate and hycrocarbon in marine oil-gas. This book consists of three
parts includin gnineteen chapters, 76 plates and 343 photos, about 500000
Chinese words. Coccolith fossils of Middle Proterozoic ages to Permian
ages are described that include 186 new species, named or unnamed, of
which 36 species were published. The cocclith fossils recently discovered
in a Middle Proterozoic iron deposit was also included. Especially, the
discovery of the Silurian Discoaster category not only made its occurrence
earlier, but also laid a foundation of coccolith classification. Research
on today's living phytoplanktons indicates that coccolith amounts to about
one third of them, Which can fix at least 30 billion tons of carbon or
110 billion tons of caron dioxide. It is of practicla importance for improving
the earth's environment and eliminate " the green house effect"
which is brought about by the excess carbon dioxide. This book is divided
into three parts:
Part I Geological outline of China coccolith fossils'
origin during Proterozoic and Palaeozoic Eras
Part II Time-mark description of China coccolith fossils during proterozoic
and Palaeozoic Eras
Part III Several quastions during coccolith fossils' discussion and research |
