Fluid Budget of Metasedimentary Rocks from a Tertiary Accretionary Prism and Connections to Seismicity, Olympic Peninsula, Northwest Washington State
<p>Metamorphic dehydration reactions and fluid movement in accretionary prisms have been linked to the recently discovered episodic tremor and slip (ETS) earthquake events along subduction zones, but prior studies lack the detail to effectively test the hypothesis that fluid flow triggers ETS …

HYDROTHERMAL FLUID TRANSPORT PATHWAYS ALONG FRACTURES AND VEINS AT BROTHERS VOLCANO, SOUTHERN KERMADEC ARC
<p>Hydrothermal fluid flow in fractures and veins is a key component in the mineralization of economic metals within calderas. But there are several methods by which fractures can form. Regional extension, episodic caldera collapse, and fluid overpressure all have the potential to create brittle …

Structural diagenesis of bed-parallel and bed-normal fractures, Cretaceous Crato Formation carbonate rocks, NE Brazil
… enhanced first by fracturing caused by elevated fluid pressures, next by fracturing caused by increasing overburden related to burial, next by jointing caused by decreasing overburden related to uplift and finally by dissolution along joint walls. Porosity was reduced by cementation of fractures, …

Aspects of material transport and polycrystal growth in fractures
… fracturing. Isotope data indicate that the fluid precipitatinig the vein was derived from an external source. Chapter 6 describes fracture sealing processes in Mesozoic limestonee, Jabal Akdhar anticline, Oman mountains. Seven different vein generations were distinguished and correlated with …
