Book excerpt: Year by year the Earth sciences grow more diverse, with an inevitable increase in the degree to which rampant specialization isolates the practitioners of an ever larger number of sub fields. An increasing emphasis on sophisticated mathematics, physics and chemistry as well as the use of advanced technology have. set up barriers often impenetrable to the uninitiated. Ironically, the potential value of many specialities for other, often non-contiguous once has also increased. What is at the present time quiet, unseen work in a remote corner of our discipline, may tomorrow enhance, even revitalize some entirely different area. The rising flood of research reports has drastically cut the time we have available for free reading. The enormous proliferation of journals expressly aimed at small, select audiences has raised the threshold of access to a large part of the literature so much that many of us are unable to cross it. This, most would agree, is not only unfortunate but downright dangerous, limiting by sheer bulk of paper or difficulty of comprehension, the flow of information across the Earth sciences because, after all it is just one earth that we all study, and cross fertilization is the key to progress. If one knows where to obtain much needed data or inspiration, no effort is too great. It is when we remain unaware of its existence (perhaps even in the office next door) that stagnation soon sets in.

Book Synopsis Early Mesozoic Tectonics of the Western Great Basin, Nevada by : R. C. Speed

Download or read book Early Mesozoic Tectonics of the Western Great Basin, Nevada written by R. C. Speed. This book was released on 1989. Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Field Trip Guidebooks Series, Volume 122. This excursion will present an overview of the stratigraphy, structure, and tectonic evolution of the margin of early Mesozoic North America in the Great Basin and of terranes tectonically accreted above and against this margin. Exposures to be visited will show the following features: 1) the Golconda allochthon, a tract of oceanic Paleozoic rocks that was thrust some 100 km across the edge of Triassic North America; 2) shelfal and platformal lower Mesozoic strata that unconformably cover the Golconda allochthon; 3) basinal lower Mesozoic strata that accumulated seaward of the inherited continental edge; 4) Mesozoic and Paleozoic arc volcanics; and 5) Jurassic and Cretaceous foreland structures developed in all the preceding rocks after accretion of terranes had left the early Mesozoic sialic margin well inboard of the active convergent margin. This guide begins with introductions to the neotectonic and Phanerozoic paleotectonic evolutions of the Great Basin. Thereafter, its contents are organized in sequence with field trip stops which are as follows [route map in Figs. 5 and 6]: Day 1. Battle Mt. Golconda allochthon. Day 2. Tobin, Stillwater, and southern Humboldt Ranges. Stratigraphy of platform to basin transition of Triassic cover, Jurassic foreland thrusting; 1915 Pleasant Valley earthquake scarp. Day 3. Sand Springs and Paradise Ranges. Terranes of volcanogenic Triassic and Paleozoic rocks structurally outboard of parautochthonous lower Mesozoic basinal and shelf edge rocks. Days 4 and 5. Mina and Candelaria. North-south traverse across structurally condensed Early Triassic collision zone of exotic Paleozoic arc, Golconda allochthon plus serpentinite melange, Golconda foreland basin strata on Early Triassic North America; these units were covered by Middle and Upper Triassic strata and imbricated with the cover in late Mesozoic foreland thrusting. Day 6. Yerington. Stratigraphy and structure of possibly oldest continental magmatic arc rocks in western Great Basin.
