Center for volcanic and tectonic studies, Department of Geoscience, Univ. of Nevada, Las Vegas, NV. Annual report No. 69, October 1, 1991--September 30, 1992

Abstract

INTRODUCTIONThe annual report of the Center for Volcanic and Tectonic Studies (CVTS) contains a series of papers, maps, and reprints that review the progress made by the CVTS between October 1,199 1 and December 3 1,1992. During this period CVTS staff focused on several topics that had direct relevance to volcanic hazards related to the proposed high-level nuclear waste repository at Yucca Mountain, Nevada. These topics included:(1) The role of the mantle during regional extension.(2) The structural controls and emplacement mechanisms of Pliocene/Quaternary basaltic centers and dikes.(3) The detailed geochemistry of individual volcanic centers in Crater Flat, Nevada.(4) Estimating the probability of disruption of the proposed repository by volcanic eruption (this topic is being studied by Dr. C-H. Ho at UNLV). Activities CVTS Organization of the Annual ReportThis report includes the following contributions: Martin (CVTS-UNLV).Activities of Tim Bradshaw; October 1, 1992 to December 30,1992.Copies of abstracts submitted by CVTS staff during the year of funding.These include:(a) "New insights on structural controls and emplacement mechanisms of Pliocene/Quaternary basaltic dikes, southern Nevada and northwestern Arizona" by ABSTRACI-One of the fundamental questions in areas. of large-magnitude extension and magmatism is the role of the mantle in the extension process. The Lake Mead area is ideally suited for developing models that link crustal and mantle processes because it contains both mantle and crustal boundaries and it was the site of large-magnitude crustal extension and magmatism during Miocene time. In the Lake Mead area, the boundary between the amagmatic zone and the northern Colorado River extensional corridor (NCREC) parallels the Lake Mead fault system (LMFS) and is situated just to the north of Lake Mead. This boundary formed between 11 and 6 Ma during and just following the

“…Instead of being only a political doctrine, national identity is a collective cultural phenomenon (Smith, 1991: vii; Spillman, 1997: 6–11) that heavily influences how people talk, think, and act (Calhoun, 2004 [1997]: 11). Nationality by no means is a natural way to classify people and having a state machine is insufficient to imbue people with a national consciousness.…”
