Empirical plotting of four sets of equidistantly spaced shear stress trajectories, based on regularities in distribution of actual faults and ore veins in the continental area and on the landward prolongation of the big fracture zones of the northeastern Pacific, givesrise to a prospecting net for the western United States. Preferential accumulation of big ore deposits (including such deposits as Bingham and Tintic) along landward prolongation of the main fracture zones of northeastern Pacific, in the vicinity of intersections of four systems of trajectories, and along boundaries of crustal blocks suggests several possibilities for prospecting for unknown hydrothermal deposits in the Cordilleran part of the United States.
Long-wavelength, relative high-amplitude-magnetic anomalies obtained at satellite altitudes have provided an understanding of the nature of the deeper crust of the Earth. We have studied two such long-wavelength anomalies in regions of high stress-one with a large and one with a lower amplitude anomaly. The first feature is on the Canada Basin continental margin in the Northwest and Yukon Territories, Canada (magnetic anomaly range: 19 nT to −6 nT at 350-km altitude). This area is also the focus of significant stress and earthquake activity. We interpret this anomaly and associated tectonic activity with this region's position at or near the fulcrum of the scissors-like opening of the Canada Basin in the mid-Mesozoic Era. The second is a section along the 40• N (latitude) parallel crossing the Korean Peninsula (magnetic anomaly range: <−2 nT to >3 nT at 350-km altitude), where an east-west fracture zone has been proposed to extend from northeastern China, across the Korean Peninsula, Sea of Japan and (Northern) Japan.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
