摘要:
The results of drilling the Toa Baja hole will help answer some fundamental questions about the evolution of the Puerto Rico area. What is the thermal history of the arc massif, and its relation to deep and shallow fluid circulation, and the cooling effects of the down‐going slab? What were the sedimentary environments of Eocene, Oligocene and Miocene time, and what is the origin of the North Coast Tertiary Basin? What is the nature of organic matter and fluids in the borehole, and their relationship to paleoenvironments of deposition, thermal regime, and flow through porous media? What are the stress orientations and fracture characteristics in the North Coast Tertiary Basin, and their relation to regional tectonic motion

摘要:
Science moves forward with the development of new ideas that are encapsulated by hypotheses whose aim is to explain the structure of data sets or to expand existing theory. These hypotheses remain conjecture until they have been tested. In fact, Karl Popper advocated that a scientist's job does not finish with the creation of an idea but, rather, begins with the testing of the related hypotheses. In Popper's [1959] advocation it is implicit that there be tools with which we can test our hypotheses. Consequently, the development of rigorous tests for conceptual models plays a major role in maintaining the integrity of scientific endeavor [e.g., Greenwood, 1989].

摘要:
Subduction zones are the most dynamic tectonic environments on the face of Earth. Most subduction zones are submarine and at many, large accretionary prisms are formed of sediments scraped from the subducting oceanic lithosphere. These prisms grow in a water‐saturated environment; consequently, their tectonic, thermal and chemical evolution is strongly influenced by fluids, and the role of the aqueous phase must be considered in any study in this realm.In view of widespread and growing interest, the North Atlantic Treaty Organization and National Science Foundation sponsored the workshop “The Role of Fluids in Sediment Accretion, Deformation, Diagenesis and Metamorphism at Subduction Zones,” which convened September 19–23, 1988, at Il Ciocco, Tuscany, Italy. This meeting assembled 60 geologists, geochemists and geophysicists representing eight countries whose interests spanned both marine and continental envir
