They depend for their existence on the presence of layering or a planar fabric, and their form depends on rheological properties, initial layer configuration, and on the history and intensity of deformation. Planar anisotropy is an important property of rocks, and it arises from preferred alignment of grains or crystallographic fabric, or from the alternation of isotropic layers of unlike viscosity. This project focuses on the role of anisotropy in the development of folds, in particular their shape and associated strain pattern, with various starting configurations and kinematic conditions of the deformation in which folds form in rocks. The ultimate objective is to use the information gained using numerical models to determine the range of possible rheological properties and kinematic conditions under which natural folds form in rocks, and thus to better understand crustal deformation. ; Oh +' 0 $ H l S u m m a r y I n f o r m a t i o n ( D h R:\WWUSER\TEMPLATE\NORMAL.DOT 9526945 Felicia Smith Felicia Smith @ ? @ @ ? @ Microsoft Word 6.0 1 ; ! ! !

They depend for their存在分层或平面织物的存在，它们的形式取决于流变特性，初始层配置以及变形的历史和强度。特别是它们的形状和相关的应变模式，具有各种起始构型和变形的运动条件，其中折叠形成岩石的最终目标是使用数值模型获得的信息来确定可能的流变学特性和运动学条件的范围，并在岩石中形成自然折叠，从而更好地理解了岩石上的构层变形。 ;哦， +'0 $ h l s u m a r y i i n f o r m a t i o n（d h r：\ wwuser \ template \ template \ normal.dot 9526945 felicia smith smith felicia felicia smith @ @ @ @ microsoft @？ @ microsoft Word 6.0 1;！！史密斯 - \\ clm12 \ earteshr \ 1995sept \摘要\ hudles.txt @hp laserjet iiid lpt3：hppcl5a hp laserjet iiid 8d r hp laserjet iiid iiid iiid 8d r r
