(2003): Origination and extinction through the Phanerozoic
: a new approach.
For the Phanerozoic
, the estimates of arreos pheric pC[O.sub.2] levels are not only internal ly inconsistent, but they also do not show any correlation with the paleoclimate record (Fig.
This contrasts with Phanerozoic
orogens such as the Appalachians, which still have strong modern-day topographic expression more than 300 Ma after cessation of orogeny.
Indian Shield: Precambrian Evolution and Phanerozoic
The sedimentary composition and particular sequence stratigraphic position of the microbialitic bioherms from Series 3 and Furongian series of Shanxi Province provide significant information for the future understanding of the formation mechanism of bioherms during "the first episode of the Cyanobacteria Calcification Events in the Phanerozoic
" or "a resuscitate period of microbial carbonate from Cambrian to the Early Ordovician".

It is known that one of the largest mass extinction events of the Phanerozoic
marked this boundary, and the record of this geologically historic event has been revealed at several stratigraphic sections over the world, most commonly from the subsurface and much less so from outcrop [1-3] due to obliteration by surface geologic processes (weathering and erosion).
