在埃及西部沙漠中白圣系一第三系界线上已采集了两条剖面的样品.一条在达赫拉绿洲附近的Gebel Gifata(29.0E,25_5N),另一条位于哈尔加绿洲附近的Abutatur碑酸盆矿(30.50E, 25.50N).岩石系列的主要构成是石灰岩和页岩,磁性很弱.由于1411面的许多部位被岩屑夜盖,、所以要从白圣系一第三系的界线上进行完整的米样是不可能的.针饮矿的存在也不适宜进行古地磁研完.但是从达赫拉绿洲的Ge.bel二 Gifata附近的七条不含针铁矿的剖面得到的特征刹余磁化方向(六条正常,一条具有倒转极性)D=357_60E, I =32.0’.由此,计算出的虚地磁极方位为224.7’E, 81.50N, A=8.50.这一磁极位置与埃及其它地区的上白圣纪一下第三纪磁极位置是十分一致的(Schult等).
Two sections of the sample have been collected on the Tertiary-Tertiary line in the western desert of Egypt, one at Gebel Gifata (29.0E, 25-5N) near Dakhla Oasis and the other at Abutatur (30.50E, 25.50N). The main components of the rock series are limestone and shale, which are weakly magnetic. Since many parts of the 1411 surface are covered by rock fragments, It is not possible to conduct a complete sample on the line of demarcation.It is not appropriate for the presence of pinot deposits to carry out palaeomagnetic studies.But from the seven sections without goethite near Ge.bel II Gifata in the Dahela Oasis (6 normal, one with inverted polarity) D = 357_60E, I = 32.0 ’. Thus, the calculated virtual ground magnetic pole orientation is 224.7’E, 81.50N, A = 8.50. This pole The location is similar to that of the Paleochronic Pole in other parts of Egypt (Schult et al.).
