四川巫山大庙龙骨坡是我国学者黄万波等新发现的重要人类化石点。化石点露头的磁性地层学研究是在总厚约18m的剖面上进行的,按照通用方法使用特制的塑料圆盒,以15—30cm的垂直间距采集了100个样品。全部古地磁工作由我所古地磁学实验室完成。样品剩余磁性用Minispin磁力仪在自控加补偿的HCM-3型零磁场空间中测量,所有样品均用TSD-1热标本退磁仪分别经:过100,150、200、250、300、350、400、450、500、550和600℃加热与冷却处理。大多数样品是在400至500℃温度段时去掉了次生剩磁组分,只保留了原生剩余磁性,所得极性以负向为主兼有多个正向。测量结果表明极性序列对应于地磁极性年代表中松山负向时的奥尔杜威正向极性亚时至留尼汪正向极性亚时,其中含人类化石层位相当于古地磁样品11.6m处,正对应于 Dragon Slope of Wushan Temple in Sichuan Province is a newly discovered important humanized fossil point by Chinese scholar Huang Wanbo. Fossil point outcrop magnetic stratigraphy studies were conducted on a section of about 18 m in total thickness. 100 samples were collected at 15-30 cm vertical spacing using a custom-made plastic box according to a common method. All of the paleomagnetic work done by our old magnetic laboratory. The residual magnetism of the sample was measured with a Minispin magnetometer in a self-controlled and compensated HCM-3 zero-magnetic field space. All samples were subjected to TSD-1 thermal specimen demagnetizer over 100,150,200,250,300,350,400,450 , 500, 550 and 600 ° C heating and cooling treatment. Most samples remove secondary remanence components at 400 to 500 ° C, leaving only the primary residual magnetism. The resulting polarity is mainly negative and multiple positive. The results show that the polar sequence corresponds to the positive polar subduction of Orduwi in the negative direction of Matsuyama in the geomagnetic polarity year and the positive polarity of Reunion when subtended by paleomagnetic samples 11.6m Department, is corresponding to
