1中国黄土磁颗粒分析及其古气候意义显示文摘本文运用岩石磁学方法,对各地黄土和古土壤样品进行低温磁化率、频率磁化率和低温剩磁退磁的研究,证明了黄土中的磁颗以顺磁(单畴和多畴,即>0.03μm)为特点,而古土壤以超顺磁(<0.03μm)为主要特征.黄土中的磁铁矿相对含量(占天然剩磁强度的百分比)比古土壤高,黄土频率磁化率的波谷、波峰分别与剖面黄土和古土壤的风化或土壤化程度相关,说明在黄土形成古土壤的成土过程中,是由于许多细小铁磁性矿物(磁赤铁矿和磁铁矿)生成,使其磁化率增高.这些细小铁磁性矿物的含量反映了古气候温湿程度的强弱和持续时间的长短.刘秀铭 刘东生 Friedrich Heller 许同春 1991中国科学(B辑)1991,,6:62
2华南早三叠世的古地磁学与大地构造显示文摘从华南几个具代表性地点的下三叠统灰岩中,获得了有意义的古地磁学初步结果.这些结果支持华南存在分离板块的设想.根据新近获得的地质与古地磁学证据,推断华南存在4个岩石图板块.它们是扬子(D=232.4°,I=-11.8°,K=28.2,α95=5.5°),湘桂(D=198.0°,I=32.2°,α95=12.9°),华夏(D=88.0°,I=13.0°,K=20.1,α95=9.1°)和海南(上二叠统D=338.2°,I=15.9°,K=10.2,α95=14.3°)板块.4个板块的古地磁极位分散,纬度差明显,并存在碰撞后的局部与区域性的旋转作用,尤其是顺时针旋转.华南早中生代的大地构造可理解为4个来自古特提斯和冈瓦纳的岩石圈碎块与欧亚大陆聚合作用的产物.陈海泓 孙枢 李继亮 许靖华 Maja.Haag Jom Dobson Friedrich Heller 1994地质科学1994,29,1:54
3中国黄土磁化率与第四纪古气候研究显示文摘本文以实验数据证明,黄土磁化率的高低与其经历的风化或土壤化强度密切相关,风化程度决定了磁铁矿的生成最及其颗粒的细小程度,从而决定了磁化率的高低。因此,与土壤化程度密切相关的中国黄土地层记录了第四纪古气候变化。刘秀铭 刘东生 Friedrich Heller 许同春 1992地质科学1992,27,A12:40
4云南思茅地区新生代的持续旋转显示文摘新生代早期(约45 Ma),印度板块在经历了长时期的北向漂移后终与欧亚大陆碰撞。其后,以印度洋的扩张作用为驱动力,印度板块持续向欧亚大陆推挤,使造山带地区产生大规模的陆壳缩短,造就了壮观的世界屋脊——青藏高原。70年代中期。陈海泓 郝杰 Jon P.Dobson Friedrich Heller Kennech J.Hsū 1993科学通报1993,38,24:13
5华南与扬子板块早三叠世分隔的古地磁学初步证据显示文摘在“华南中生代造山作用”这一设想中,华南主要存在三个岩石圈板块:扬子板块,华南板块与东南亚板块。扬子板块与华南板块在前中三叠世处于分离状态,其间可能存在一洋盆,许靖华等曾称之为“板溪洋”。为进一步验证这一科学预见,作者于1989年10月与12月。陈海泓 孙枢 李继亮 许靖华 Friedrich Heller Jon Dobson 1992科学通报1992,37,6:5
6Paleomagnetic age and palaeobiological significance of hominoid fossil strata of Yuanmou Basin in Yunnan显示文摘The two sections containing hominoid fossils in the Yuanmou Basin, Yunnan Prov-ince have been studied by means of magnetostratigraphy. The results are as follows. The Xiaohe section records over 8 polarity zones corresponding to Cande-Kent95 time scale, including C3Br.1n, C3Br.1r, C3Br.2n, C3Br.2r, C4n.1n, C4n.1r, C4n.2n and C4n.2r, attaching to Late Mio-cene. This section comprises two layers of hominoid fossils: the lower layer (the 1st layer in fig. 4) which records the lower portion of C4n.2r with paleomagnetic age of 8.20—8.10 Ma and the upper layer (the 16th layer in fig. 4) which records C3Br.1r with paleomagnetic age of 7.20—7.15 Ma. So the age of hominoid fossils in the Xiaohe section is about 8.20—7.15 Ma. The Leilao section records over 11 polarity zones corresponding to Cande-Kent95 time scale, including C3Br, C3Br.1n, C3Br.1r, C3Br.2n, C3Br.2r, C4n.1n, C4n.1r, C4n.2n, C4n.2r, C4n.3n and C4n.3r, attaching to Late Miocene. This section also consists of two layers of hominoid fossils: the lower layer (the 3rd layer in fig. 3) which records C4n.2r with the age of 8.20—8.10 Ma and the upper layer(the 19th layer in fig. 3) which records the middle portion of C3Br with the age of 7.15—7.1 Ma. So the age of hominoid fossils in the Leilao section is about 8.20—7.10 Ma. Sedimentary environments reflected in both sections are extremely similar, and the ages of hominoid fossils are of correspondency. The age of the lower and upper fossil layers is 8.20—8.10 Ma and 7.20—7.10 Ma respectively, which probably imply that hominoids living in Xiaohe and Leilao basins have uniform activity areas. There were hominoids activities all along during 8.00—7.00 MaBP in this field.Friedrich A. Heller 2004Science China Earth Sciences2004,47,5:1
7Permo-Triassic Magnetostratigraphy in Wulong Area, Sichuan, China显示文摘The Permo-Triassic boundary in Wulong area, Sichuan Province, South China lies in a continuous marine carbonate succession with abundant fossil records. Two well-exposed sections were sampled for magnetostratigraphic studies. The experimental results of rock magnetism reveal that the samples from the Triassic limestones contain only magnetites among which 70% are multi-domain. The ChRM direction is carried by remaining 30% of single-domain magnetite. The Permian limestone samples are dominated by single-domain to superparamagnetic magnetites with little ChRM direction due to their fine-grained texture. Nevertheless, the polarity determination is still possible based on the NRM vector changes during thermal demagnetization. A Permo-Triassic polarity profile in Wulong area is established in the paper, and a tentative correlation with other known profiles is pursued. The authors suggest that the Illawarra reversal starts at the upper part of Wujiapingian, while some normal polarity events may exist in陈海泓 孙枢 李继亮 FriedrichHeller JonDobson Friedrich Heller and Jon Dobson 1994Science China Chemistry1994,37,2:1

11四川凉桥晚二叠世磁性地层学剖面显示文摘极性年表的问世使地层对比,尤其是洲际地层对比的精度大大地改善.然而,目前获得普遍接受的极性年表仅限于新生代与晚中生代.中侏罗世之前的极性转换历史,则因缺少大洋磁异常带以资对比而无广泛认同的标准.因此,若建立这一时期的极性年表,大量的洲际对比是必须的.陈海泓 Friedrich Heller 1994科学通报1994,39,1:1
