Lake PleasantSouth Park Rd. Joel Leonard GLG 310 Structural Geology Final Presentation
Scope • Generally identify/categorize major lithologic units in the area • Identify structural features within the units • Set temporal boundaries for structural features
Observations Stratified Breccia – Fan Breccia/Debris Flows
Observations Felsic Igneous: Flow foliated
Observations Gneiss: nice…
Observations Intrusion Breccia
Observations Roadcuts…
Observations The Missing Link
Conclusion • Area is dissected by at least two temporally distinct intrusive igneous events. • Felsic intrusions pre-date mafic intrusions • Mafic intrusions occurred syndepositionally to Fan breccia/Debris flow breccia. • Faulting occurs last • Felsic intrusions>Deposition>Mafic Intrusions>Deposition>Faulting
