ZPLOTIT The ZPLOTIT software package produces vector demagnetization diagrams, intensity-decay plots, and stereonets and computes the principal component analysis (PCA) from paleomagnetic data sets. See Example Plots Example PCA Table Example Animated GIF ZPLOTIT: Readme.txt ZPLOTIT: PDF Manual ZPLOTIT is available for use free of charge. ZPLOTIT, the subroutines it uses, and a Makefile are available in gzip/tar format or Stuffit format in files: Zplotit.tar.gz: Download the gzip and tar file. Zplotit.sit: Download the Stuffit file. For bug reports and suggestions for improvement, E-mail Gary Acton at gdacton@ucdavis.edu.

ZPLOTIT PLOTS

The plots created by ZPLOTIT are illustrated for an ANDRILL sample (Acton et al., 2008). a) Upper left: Vector demagnetization diagram or Modified Zijderveld plot. b) Upper right: Same as that to the right, except zoomed in by 3x. c) Lower left: Intensity-decay diagram. d) Lower right: Stereonet (equal-angle; Wulff projection) with directions plotted.

An example of the PCA table for a few samples from Afar, Africa (Acton et al., 2000).



ZPLOTIT Animated GIFS

The merged.pdf file created by ZPLOTIT can easily be converted to an animated GIF using Imagemagik (http://www.imagemagick.org/) and GIFsicle (http://www.lcdf.org/gifsicle/). Once those software were installed, the animated GIF was created using this shell script. Click on the image to the left to see the animated GIF (preliminary demagnetization data from Acton and Herrero-Bervera, in prep.)
