ABSTRACT

A new algorithm for detecting potential dispersal trains in geochemical data sampled from till is presented. This algorithm, referred to as the dispersal train identification algorithm (DTIA), is written in visual basic (VB) and can be run from any Microsoft application that supports VB. A Microsoft word document is supplied that contains the code and the program can be run from this document. A users manual, a previously published paper describing DTIA and a test dataset for experimentation purposes, is also contained. The code has not been optimized (i.e. excessive error checking) and will not be further supported by the Geological Survey of Canada. The user is free to modify the code to suit individual needs.

CAVEAT

The code for this algorithm (DTIA) was originally written in FORTRAN and has been re-written in visual basic (VB). The code is certainly not optimized and can be improved. Since the VB code has been included VB literate users are welcome to modify the code to meet individual requirements. There are no plans at this point to further support  or modify DTIA  by the original authors. However, the authors welcome any comments and suggestions on DTIA that users may have. Users may contact Jeff Harris (harris@nrcan.gc.ca) at the Geological Survey of Canada.
