A comparison of chemical data from Lakes Hoare, F, V, and B with data on local source rocks shows that mixing of source rock is a major factor in determining the composition of these soils/sediments. Using data collected from spectrographs, the percentage of each element present in a sample is determined. "This rock is a close match in chemical composition to an unusual but well-known type of igneous rock found in many volcanic provinces on Earth," said Edward Stolper of the California Institute of Technology in Pasadena, who is a Curiosity co-investigator.
