Objective(s): To conduct a geological survey and rock sampling in the Acasta Gneiss Complex to investigate evolution of the early earth.
Project Description: The objectives are to conduct a geological survey and rock sampling in the Acasta Gneiss Complex to investigate evolution of the early earth. The Acasta Gneiss is the oldest rock in the world, and uniquely records the early earth. The Acasta Gneiss has many generations and a complex history including not only the magmatic formation with different ages but also deformations. Comprehensive works on geology, igneous and metamorphic petrology and geochemistry are necessary in order to collect vestiges of early earth. The research team will make a geological map in the Acasta Gneiss Complex to establish the field occurrence of mafic enclaves. The research team will walk around the Acasta Gneiss Complex, 5 km x 5 km area and collect rock samples for laboratory research of geochemistry, petrology and geochronology. The team will use hand held hammers. The use of the hand hammers held minimizes damage to nature. The research team will send thesis and reports as well as academic papers to communities. Two PhD students are studying the geology and geochemistry of the Acasta Gneiss Complex and will report the results in academic journals. The fieldwork for this study will be conducted from August 6, 2015 to August 31, 2015.
