Tectonics Of Saturn's Moon Titan And Tsunami Modeling Of The 1629 Mega-Thrust Earthquake In Eastern Indonesia, Yung-Chun Liu
Tectonics Of Saturn's Moon Titan And Tsunami Modeling Of The 1629 Mega-Thrust Earthquake In Eastern Indonesia, Yung-Chun Liu
Theses and Dissertations
Chapter 1-2:The Cassini RADAR mapper has imaged elevated blocks and mountains on Titan we term ‘ridges’. Two unresolved problems regarding Titan's surface are still debated: what is the origin of its ridges and was there tectonic activity on Titan? To understand the processes that produced the ridges, in this study, (1) we analyze the distribution and orientation of ridges through systematic geomorphologic mapping and (2) we compare the location of the ridges to a new global topographic map to explore the correlation between elevation and ridges and the implications for Titan's surface evolution. Globally, the orientation of ridges is nearly …
The Rice Bay And Northeast Bay Gneiss Domes: A Kinematic Study Of Competent Rock Bodies In The Rainy Lake Region Of Ontario, Canada, Jane Block
Theses and Dissertations
The Rice Bay and Northeast Bay gneiss domes (RBD and NEBD) are two tonalitic rock units located in the Archean Rainy Lake zone of the Superior Province. The Rainy Lake zone acts as a boundary between two subprovinces, accommodating transpression, significant shortening and dextral motion in its lithologic assemblage. This study contributes to understanding how deformation is partitioned in heterogeneous terranes, and also demonstrates a practical method of kinematic analysis. Foliations, lineations, shear zones, tension gashes, quartz veins, mafic enclaves, and folded and boudined veins were all utilized in the kinematic analysis. Foliation orientations in both domes are consistent with …
