  palaeomagnetism characteristics
     Based on the study on palaeomagnetism characteristics of Permian-Triassic occurring in Pantaoyuan of Tulufan, rnagnetical stratigraphical column was established. The border was confined between 37th layer and 36th layer (viz 66-65 spot) in lower Guodikang formation.

This paper, based on the test result of paleomagnetism after alternating demagnetization, relates to the properties of the poleomagnetic characteristics and the stratigraphic divisions of the loess in Zhang Bian Yuan.

本文通过交变退磁后的古地磁测定结果,着重讨论了张汴塬黄土古地磁特征及黄土地层划分。古地磁测定结果表明:早更新世与中更新世黄土界线和布容与松山之间界线吻合,在剖面的下粉砂层顶部。中更新世黄土始于73万年。在布容正极性世中,第二层古土壤中出现反极性标本,有可能是反极性事件。早更新世沉积物中显示出哈拉米洛与奥尔都维两个事件。最底部出现的正极性标本可能是留尼昂事件的反映,因此陕县黄土可能形成于240万年左右。在中国黄土中发现留尼昂事件的剖面还不多。为进一步搞清这几个事件,目前正在进一步工作。此外本文还研究了标本的虚磁极位置,以及强度与岩性的关系。

This paper describes the paleomagnetism on middle Paleozoic rocks from western Zhe-jiang and southern Anhui of the Yangtze Plate, South China. According to the remmanent magnetization it is revealed that natural remmanences from middle Paleozoic rocks were com-posee of two or three components isloated from stepwise demagnetized vectors. Stability testes,such as fold test, fabric tedt,ect. , indicate that characteristic remmanent magnetiza- tions were primary. The mean directions and their poles of relatded ages...

This paper describes the paleomagnetism on middle Paleozoic rocks from western Zhe-jiang and southern Anhui of the Yangtze Plate, South China. According to the remmanent magnetization it is revealed that natural remmanences from middle Paleozoic rocks were com-posee of two or three components isloated from stepwise demagnetized vectors. Stability testes,such as fold test, fabric tedt,ect. , indicate that characteristic remmanent magnetiza- tions were primary. The mean directions and their poles of relatded ages in middle Paleozoic for Yangtze Plate have been obtained by applying two-tier stazistics. The results show that the western Zhejiang and southern Anhui region remained in southern equatorian latitudes during early Paleozoic,but moved by large scale absoute anticlockwise rotation between middle Silurian and early to middle Devonian.

The development and evalution of the Qinlin Rift discussed taking theresearch resuIts as dominant factors indicate that the rift was closed to the end of Caledonian epoch and re-vived during Hercynian and Indo-chinese epoch,Therefore the strata-bound lead-zinc deposits...

The existence of the Qinlin Rift has been demonstrated based upon the characters of basement stracture,deep-seated fauIt,lithofacies and paleogeography ,magmatism, paleomagnetism and the comparison betweenstrata-bound ore deposits of rift type. The development and evalution of the Qinlin Rift discussed taking theresearch resuIts as dominant factors indicate that the rift was closed to the end of Caledonian epoch and re-vived during Hercynian and Indo-chinese epoch,Therefore the strata-bound lead-zinc deposits of Qinlin Rifttype were formed.The plates on the both sides of the rift came into collision each other upto the end of Indo-chinese epoch.Finally the relationship between rift and mineralization were discussed,and the characters ofsome rifts in china were compared with those of some continental rifts in the world.

从基底构造、深大断裂、岩相古地理、岩浆活动、古地磁特征和裂谷型层控矿床比较等6个方面论证秦岭裂谷的存在。以古地磁成果为主导,探讨了秦岭裂谷的发生发展演化,到加里东末期裂谷曾锁闭,海西印支期再复合,从而有秦岭裂谷型层控铅锌矿床的形成,直到印支末期裂谷两侧析块才碰撞对接在一起。文章最后论述了裂谷构造与成矿关系,我国若干裂谷构造特征与世界大陆裂谷的比较。
