The paper on asbestos by Gibbons illustrates the breadth of studies in environmental geochemistry , and highlights the multi-disciplinary approach required, including in this case an understanding of political and social issues.
The rock's geochemistry and mineralogy also strongly suggest to astronomers that it was heated substantially early on in its existence and that liquid water has coursed through its veins.
The petrology and geochemistry of these volcanic rocks show that they form an essentially bimodal association of basalt and subalkaline rhyolite, with less common intermediate compositions.
The major and trace element geochemistry of these rocks is consistent with a rift setting, as is their association with a lithostratigraphic protolith package of carbonates, shales and greywackes.
The field-based studies were supplemented by thin-section petrography and whole-rock geochemistry to characterize different intrusive phases.
Will collaboration with other geologists, such as sedimentary isotope geochemists or paleoceanographers, provide the necessary insight and data?
This is also supported by the petrological and geochemical characteristics of the mafic magmatism associated with the granitoids.
From extensive databases of solubility constants and their dependence on bulk solution chemistry, geochemists can determine which minerals are dissolving or precipitating.
The geophysical and igneous geochemical evidence suggests this has greater similarity with Avalon than the Midland Valley Terrane.
Trace elements and oxygen isotopes are useful geochemical indicators of the chemistry of the waters from which the chert precipitated.
