| 摘 要： | 我们对江苏南部中、下泥盆统茅山砂岩进行了古地磁初步研究.结果表明:(1)杨子地块早、中泥盆世时期处于赤道附近;(2)在晚侏罗一早白垩世期间,宁镇山脉相对于无锡地区顺时针水平旋转了37．5°,茅山山脉在晚白垩世相对无锡地区逆时针水平旋转了30．7°,(3)宁镇和茅山地区茅山砂岩的层位,似应上升到无锡地区茅山砂岩的上段中、下部. |

| Abstract: | Preliminary paleomagnetic studies have been conducted on the Middle-Lo wer Devonian Maoshan sandstone in southern Jiangsu. The result shows: (1) the Yangtze massif was located near the equator during the Early-Middle Devo nian; (2) the Ningzhen mountain range had a clockwise horizontal rotation of 37.5°relative to Wuxi area during the Late Jurassic-Early Cretaceous, while the Maoshan mountain range performed a counterclockwise horizontal rotation of 30.7°relative to Wuxi area in the Late Cretaceous; (3) it seems that the stratigraphic horizon of Maoshan sandstone in Ningzhen and Maoshan areas shou ld be raised somewhat so as to correspond to the middle and lower part of Upper Member of Maoshan sandstone in Wuxi area. |
