Snowball Earth to Global Warming: Coupled vanadium-carbonaceous deposits in the Cryogenian-Cambrian
نویسندگان
چکیده
The anticipated high demand for new vanadium resources in support of the green energy revolution will be partly met by carbonaceous deposits. This type deposit is particularly developed during a 200 Myr period from Cryogenian-Cambrian. During this period, anoxic conditions were widely and provided template deposition. Vanadium became available to surface Neoproterozoic when anomalously levels introduced large igneous provinces. Global glacial erosion transported oceans, along with trace elements that engendered organic carbon accumulation. combination gave rise range deposits, provides model exploration further resources.

Snowball Earth climate dynamics and Cryogenian geology-geobiology
Geological evidence indicates that grounded ice sheets reached sea level at all latitudes during two long-lived Cryogenian (58 and ≥5 My) glaciations. Combined uranium-lead and rhenium-osmium dating suggests that the older (Sturtian) glacial onset and both terminations were globally synchronous. Geochemical data imply that CO2 was 102 PAL (present atmospheric level) at the younger termination, ...

متن کاملA neoproterozoic snowball earth
Negative carbon isotope anomalies in carbonate rocks bracketing Neoproterozoic glacial deposits in Namibia, combined with estimates of thermal subsidence history, suggest that biological productivity in the surface ocean collapsed for millions of years. This collapse can be explained by a global glaciation (that is, a snowball Earth), which ended abruptly when subaerial volcanic outgassing rais...

The tendency of the atmospheric angular momentum (AAM) is investigated using a 49-year set of monthly AAM data for the period January 1949± December 1997. This data set is constructed with zonal wind values from the reanalyses of NCEP/NCAR, used in conjunction with a variety of operationally produced AAM time series with dierent independent sources and lengths over 1976±1997. In all the analyz...
متن کاملAftermath of a snowball Earth
[1] Using a simple 3-box model of the ocean-atmosphere system, we simulate the cycling of carbon and strontium in the aftermath of a global glaciation. Model simulations include the delivery of alkalinity to seawater from intense carbonate and silicate weathering under high pCO2 conditions as well as ocean mixing, air-sea gas exchange, and biological productivity. The dC of the first carbonate ...
