作者： Irshad Ahmad 1,Joseph A. DiPietro 2(1.nce in Geology, University of Peshawar Pakistan 2.Department of Geology, University of Southern Indiana, evansville,IN 47712,USA)

North of the study area in lower Swat, the rocks have been found to have undergone multiple deformations with at least four periods of folding during a single Paleogene metamorphism (DiPietro and Lawrence, 1991). The earliest folds are composite W—SW vergent, syn\|metamorphic F 1/F 2 folds associated with the formation of the regional foliation. Late\|metamorphic, N—S trending open upright F 3 folds are associated with local foliation development, and e—W trending open F 4 folds are associated with retrograde metamorphism. These interfere with each other to produce dome/basin structures.

夏洛克是莎士比亚笔下的犹太高利贷者 ,他贪婪、冷酷、毫无人性 ,一直受到人们的嘲笑和唾骂。但夏洛克之所以如此 ,其根源是社会矛盾造成的。他一面虔诚地读着圣经 ,一面拼命攒钱 ,过着清教徒的生活 ,然而他的复仇意识很强 ,但到头来落得人财两空。从中我们可以了解当时基督教社会的所谓“仁慈 ,公正”
