The Erlangen geological and mineralogical software collection1
The Erlangen Geology Website offers a collection of computer programs written by members of our department for solving geological and mineralogical problems. The programs are small applications for settling time calculation (Centrifuge, Atterberg) or X-ray data conversion and processing (Theta, Qfact) as well as complex analysis tools. Winfit! is a program for profile analysis of X-ray reflections by peak fitting that can also be used to obtain size and strain information on the sample investigated. Crossbed is a tool for plotting and back rotation of crossbed measurements for palaeocurrent analysis. WinTek handles structural geology data, plots projections, rotates datasets, counts and produces filled contour lines. Winstruct can be used for simulating 001-diffraction patterns from clay minerals. It allows incorporation of varying chemistry, different atomic positions, instrumental parameters, particle orientation and particle size into the calculations. Convolution of the calculated patterns with a broadening function models instrumental contribution to peak breadth. The site is completed by a collection of links to software from other authors. Some of this software is described on the Web page. Additionally there is a Web-searchable database that contains information about the programs listed on this site supplemented by entries and links to software available on other Web-Sites. Software authors can add their programs, including a short description and key-words, as well as URLs of homepages and download facilities by a Web-form. On submission, the database is updated immediately.
