1. Chronostratigraphy and paleomagnetism of the Balsas Group in the Tuzantlán-Copalillo basin, northern Guerrero state, Mexico - Molina Garza, R. S.; Ortega-Rivera, María Amabel
El relleno Cenozoico de la cuenca the Tuzantlán-Copalillo, en el noreste de Guerrero, México, se asigna a dos unidades estratigráfi cas distintas.

2. Paleomagnetism of the Dazhuqu terrane, Yarlung Zangbo suture zone, Southern Tibet - Abrajevitch, Alexandra

3. Paleomagnetic constraints on the age of the Botucatu Formation in Rio Grande do Sul, southern Brazil - Tamrat,Endale; Ernesto,Marcia
After thermal and alternating field demagnetization, both normal and reversed characteristic remanent magnetizations were found.

4. Paleomagnetism (title provided or enhanced by cataloger) - Joseph Meert; Joseph Meert
It has links to other paleomag sites, access to Gondwana paleomagnetic database, and a list of publications (some of which have links to web versions).

5. Paleomagnetism of Caacupé and Itacurubí groups, western border of Paraná Basin, Paraguai - Berquó,Thelma S.; Ernesto,Marcia; Siqueira,Roberto

7. Global Tectonics Homepage
The Global Tectonics homepage features online data and software tools for paleomagnetism and plate tectonics.

8. School of Rock Teacher Research Experiences
'School of Rock' research experiences for educators will provide opportunities to conduct geological, physical and/or chemical analyses of sediment and hard-rock cores in laboratories at the Texas A and M Gulf Coast Repository.

9. Cambrian Stratigraphy
This site describes in detail the stratigraphy of the Cambrian period, starting approximately 545 million years ago and ending about 490 million years ago.

10. What on Earth is Plate Tectonics?
The first section, entitled Into the Earth, describes the crust, mantle and core of the Earth, while the next section shows a world map with the plates delineated.

11. School of Rock
These resources were developed during a seagoing pilot teacher workshop sponsored by the Integrated Ocean Drilling Program (IODP).

12. Rapid, Precise, and High-Sensitivity Acquisition of Paleomagnetic and Rock-Magnetic Data: Development of a Low-Noise Automatic Sample Changing System for Superconducting Rock Magnetometers - Kirschvink, Joseph L.; Kopp, Robert E.; Raub, Timothy D.; Baumgartner, Christopher T.; Holt, John W.
Because the geomagnetic field varies over timescales relevant to sedimentary deposition and igneous intrusion, while the fidelity of recorded magnetization is modulated by original properties of rock units and by alteration histories, "ideal" paleomagnetic results measure remanent magnetizations of hundreds of samples at dozens of progressive demagnetization levels, accompanied by tests of magnetic composition on representative sister specimens.

13. Variations in transitional magnetic field geometries during the Matayuma-Brunhes reversal: Data from the Tatara-San Pedro volcanic complex, Chilean Andes - Pickens, James Cecil
A detailed volcanic record of the Matuyama-Brunhes (MBR) reversal (780 ka) suggests that the reversing magnetic field remains dipolar throughout the transition.

14. Evolución paleoclimática durante el pleistoceno de la mitad sur de la Península Ibérica : mediante el estudio paleontológico y geoquímico de ostrácodos de la cuenca de Cúllar-Baza (Granada, España) - Ortiz Menéndez, José Eugenio
En esta Tesis Doctoral se han abordado aspectos multidisciplinares que se han conjugado para obtener un mejor conocimiento del Cuaternario en España.

16. U.S. National Report to International Union of Geodesy and Geophysics 1991-1994
This reference source seeks to link science to societal needs by incorporating inter- and cross-disciplinary articles within the six major topics covered: properties of the solid earth (covering volcanology, geochemistry, and petrology; geomagnetism and paleomagnetism), dynamics of the solid earth and other planets (covering tectonophysics, seismology, and geodesy), space sciences (covering atmospheric studies of extraterrestrial bodies, space physics, and the Earth's atmosphere from the mesosphere and above), atmospheric sciences (covering the Earth's atmosphere below the mesosphere), hydrology (including all aspects of surface and ground water), ocean sciences (covering physical, chemical, and biological oceanography).

17. Gravitational collapse of magnetized clouds II. The role of Ohmic dissipation - Shu, F. H.; Galli, D.; Lizano, S.; Cai, M.
We formulate the problem of magnetic field dissipation during the accretionphase of low-mass star formation, and we carry out the first step of aniterative solution procedure by assuming that the gas is in free-fall alongradial field lines.

18. From Mountains to Monsoons- A Teachers Guide
The lesson plans focus on topics such as how sediment records Earth's history, dynamic modeling of the Earth's structure, how to collect sediment cores and pick drilling sites, paleomagnetism and how to trace the previous locations and movements of tectonic plates, how to look for evidence of uplift in the sedimentary record, and the physical processes involved in the development of monsoons.
