Abstract | Bulk geochemical data are routinely used in exploration and delineation of iron ore deposits. Increasingly, hyperspectral optical reflectance spectroscopic data are also used to offer complementary
mineralogical and mineral chemical information. Herein we provide bulk geochemical and spectrally determined mineralogical data for several case examples of iron deposits, as well as high-resolution bulk geochemical data for Carlin-type Au and
volcanogenic massive sulfide (VMS) deposits. These are used to illustrate the utility of linking disparate data sets through a downhole drill core protocol to allow for more effective analysis of these data sets. Such data integration should become
routine in the future, in preparation for effective evaluation and interpretation of increasingly higher resolution data sets. |
Summary | (Plain Language Summary, not published) The Targeted Geoscience Initiative (TGI-4) is a collaborative federal geoscience program that provides industry with the next generation of geoscience
knowledge and innovative techniques to better detect buried mineral deposits, thereby reducing some of the risks of exploration. This presentation and conference proceedings paper discusses how disparate geological and geochemical datasets can be
queried to examine geological and geochemical relationships that would previously have not been possible through the use of novel computer software. |
