Evolution of Fracture Networks in the Upper Oceanic Crust.

Abstract

The long term objective of this project was to establish realistic geologic constraints on the variables which contribute to the seismic signal in the upper oceanic crust, and to determine how these variables evolve with age. To begin to address this problem, our short term objective was to characterize the nature of porosity in a section of oceanic crust exposed in the Troodos Ophiolite, Cyprus. By comparing the distribution of volcanic morphologies and their inherent porosity to the distribution of void filling secondary minerals, we evaluated how porosity created by crustal accretion is modified by alteration as a section of crust ages.
