Document Summary

History of mars told by rock strata suggests that the planet underwent significant geological change. Sample is taken from the gale crater stack; huge mountain range size of rockies. Clay minerals found at bottom, transition into sulfates with clay, then sulfates w/o clay. This suggests the drying out of a once wet planet over time. Many other sample sites on mars suggest the same thing, but not as defined as gale. Nasa selected the gale crater as one of the 4 finalist sites for the rover, curiosity. Other 3 sites have water related minerals and features that distinguish them. Geologists from university of portsmouth proposing that humankind have so altered the earth that it marks a new epoch in earth"s history. mankind"s presence. Changes include sediment erosion/deposition, ocean acidification, global temperature and extinction of plants and animals. Tiny particles of plastic in sand, atomic testing residue in strata evidence. Industrialization marks the start of the anthropocene according to many.
