Relative dating geology
The soil over much of Australia, especially the dry central parts, have not been renewed by volcanic activity for a very long time and are impoverished compared to soils from most other parts of the world.
Another factor in the formation of fertile soils that was absent in Australia was glaciers.
This marker is useful for age-dating sediments deposited in the 1800s in archives where it is present.
The estimated dates for this ~ 1850 marker using other dating methods span a range of 57 years, emphasizing the importance of the marker as a tie-point for extrapolated dates in the 19th century.
Landforms The geologic history and its climatic contrasts are reflected in the landforms.
Lead isotopes combined with trace metal fluxes identified a potential marker for coal combustion or urban sources in the second half of the 20th century in southern Ontario, where these sources were significant enough to outweigh leaded gasoline input.
The Lake Eyre catchment accounts for 1.3 million km The Australian continent is unique in a number of ways.
It is the driest, flattest, oldest, it has the most erratic climate of any continent, and much of it experiences great extremes of rainfall both during a year and from year to year.
Molybdenite Re–Os age of the skarn type mineralization is 83.4 ± 2.1 Ma, and the stratiform ores hosted by basalt is 84.2 ± 7.3 Ma, which are consistent with the LA-ICP-MS zircon age of the Xinshan granite intrusion (83.1 ± 0.4 Ma).
The evidence listed above reflects the fact that different ore styles in the Kafang deposit belong to the same mineralization system.
