9903006SnyderThe Pennsylvanian of the Western Great Basin is generally thought to be a time of relative tectonic quiescence between the Devonian Antler and the Permo-Triassic Sonoma Orogenies. However, recent evidence for tight folding and thrusting to middle Pennsylvanian age in several mountain ranges of North - Central Nevada has cast doubt on this interpretation. This project will attempt to determine the extent of this deformation and to evaluate several of the existing models for this time period in the light of these new data. Results are expected to increase knowledge of the number of tectonic pulses and their timing during the late Paleozoic of the Western United States.

大盆地西部的宾夕法尼亚期通常被认为是泥盆纪鹿角和二叠纪-三叠纪索诺马造山之间的相对构造平静时期。然而，最近的证据表明，在内华达州中北部的几个山脉中，有紧密的褶皱和向宾夕法尼亚中期的突进，这让人对这种解释产生了怀疑。该项目将试图确定这种变形的程度，并根据这些新数据评估这一时期的几个现有模型。预计这一结果将增加人们对美国西部晚古生代构造脉冲数量及其时间的了解。
