T32D:
Fractures In Plutonic Rocks eLightning


Submit an Abstract to this Session


Session ID#: 48877

Session Description:
Plutonic rocks are pervaded by fractures, which are critical for studies of mineralization, geothermal energy, radioactive waste disposal, carbon capture and storage, and hydrocarbon resources. Yet geologists lack basic criteria to distinguish mechanisms of formation of fractures in plutonic rocks, and know rather little about fracture characteristics in plutons compared to sedimentary rocks. Hence, it may be difficult to separate thermally-induced, tectonic, and exfoliation fractures on outcrops, and to predict the likely sub-surface orientation, intensity and connectivity of fracturing. Contributions to this session are encouraged on fractures in any plutonic rocks, including:
1) Characterisation of fractures in plutonic rocks, from field and/or geophysical methods
2) Fracture formation, for example from field evidence and/or numerical modelling
3) Fracture systems and physical properties, for example by rock mechanics experiments or geophysical methods
4) Fractures in plutonic rocks for practical applications such as mineralization, geothermal energy, radwaste disposal, CCS and hydrocarbons.
