Small Circle Methods in Paleomagnetism

Small-circle methods provide some new ways to analyse palaeomagnetic remanences. They especially provide a geometrically alternative estimate of the palaeomagnetic field direction (cross-checking tilt correction and fold tests) and they are the key to the tectonic interpretation of synfolding remanences. These pages provide manuals and software tools (Excel worksheets, scripts for Microstation and CorelDraw)

2. Manuscripts and Comments: Some downloads

3. Techniques and Software:

Microstation CAD: handling palaeomagnetic and structural data together and in 3 dimensions. Create vectors and small circles directly in CorelDraw, using Corel script language or VBA-language Worksheets for small-circle calculations (SCI-estimates, small circle reconstruction, calculation of small circle intersections, numbers and ratios, etc.) and other common calculations (Fisher statistics, bedding correction, etc.). Microstation: handling directional data in 3 dimensions Microstation: creating dynamic reconstructions Drawing, remanences, small circles and their intersections: scripts and VBA-code for CorelDraw Worksheets for small circle calculations (intersections, SCI-estimates), Fisher statistics and other
