On the use of magnetic techniques for stratigraphic purposes : examples from the Lower Palaeozoic Anglo-Brabant Deformation Belt (Belgium)
Within the Lower Palaeozoic Anglo-Brabant Deformation Belt, magnetic susceptibility on its own does not allow for a straightforward distinction between different lithostratigraphic units, except for the high-susceptibility levels of the Lower Cambrian Tubize Formation. Moreover, the variation in magnetic susceptibility within individual lithostratigraphic units is often larger than that between different units, but at the same time, this internal variation in susceptibility may show no clear relationship to features obvious in outcrop or hand specimens. Hence, the applicability of magnetic susceptibility for stratigraphic purposes in the Anglo-Brabant Deformation Belt is low. Better results are obtained using the temperature-dependent variation in terms of percentage of magnetic susceptibility within the "room temperature interval". Also the anisotropy of magnetic susceptibility allows for a better distinction between different lithostratigraphic units than does magnetic susceptibility. The best results are obtained by a comparison of thermal demagnetisation curves of magnetic remanence, used for determining ferromagnetic mineralogy. This method even allows distinguishing lithostratigraphic units in which ferromagnetic carriers do not contribute to overall magnetic susceptibility and its anisotropy.
Ideally, each magnetic technique should be used for stratigraphic purposes only in combination with other magnetic techniques. Moreover, knowledge about the magnetic carriers (s.l.) facilitates this use of magnetic techniques and strongly improves the accuracy of the interpretations
Large-scale slumping deduced from structural and sedimentary features in the Lower Palaeozoic Anglo-Brabant fold belt, Belgium
Paper Session II-A - Expanding the Commercial Space Arena: The Western Pacific Rim States as Competitors-Markets
Space commerce over the past decade has become a field in transition as comsat markets exponentially expand with prospect for further growth in other areas also very positive. As part of this change process, new competitors are stepping forward. The Russian Federation successor state to the former Soviet Union’s space program represents one facet of that new challenge. Its competitiveness grows directly from its historic status as one of the two first space powers. A more intriguing situation is developing in the Western Pacific Rim states, there space-related activities span the spectrum from fairly comprehensive space programs to states just emerging into the space applications arena. This paper explores these changes and discusses their implications for the United States commercial space effort
The anisotropy of magnetic susceptibility (AMS) in low-grade, cleaved pelitic rocks: influence of cleavage/bedding angle and type and relative orientation of magnetic carriers
Architect\u27s Report To the Board of Trustees of the College of Agriculture, and the Mechanic Arts, of the State of Maine
The report of Frederick Law Olmsted on design considerations for the Land Grant College for the state of Maine presented in 1867.
Olmsted\u27s report begins on page 15 of the Annual Report of the State College of Agriculture and the Mechanic Arts as it appeared in Documents of the Legislature of the State of Maine, 46th Legislature, House Document no. 57. The entire document was scanned.
Olmsted discusses what he views as important and unique design considerations given the goal of the college, to provide a liberal education to those who are to remain members of the industrial classes. He notes that it is absolutely essential to the success of the institution that during the four years in which students shall be subject to its direct influence, certain tastes, inclinations and habits shall be established. Olmsted explains how these considerations can be reflected in the arrangement and use of buildings and the landscape design
