2.4 Geochemical Database<br />
The database files used by <strong>POLYMIN</strong> and their analogous MINTEQA2 files are:<br />
<strong>POLYMIN</strong><br />
alk.dbm<br />
analy.dbm<br />
error.dbm<br />
compcp.dbm<br />
type6cp.dbm<br />
thermcp.dbm<br />
MINTEQA2<br />
alk.dbs<br />
analyt.dbs<br />
error.dbs<br />
comp.dbs<br />
type6.dbs<br />
thermo.dbs<br />
Redox and gas reactions can be included in type6cp.dbm and thermcp.dbm database files<br />
within MINTOX and thus do not have their own database files. Modifications to these database<br />
files can be made relatively easily. They are in ascii format and the format/unformat routine<br />
necessary when modifying MINTEQA2 database files is not needed.<br />
To add a component to the databases edit the compcp.dbm file and insert the new<br />
component in the same format as in the comp.dbs MINTEQA2 file. To add reactions, add the<br />
reaction to both the type6cp.dbm and the thermcp.dbm files in the same format as the reaction<br />
occurs in the MINTEQA2 database files. The <strong>POLYMIN</strong> program does not need to be<br />
recompiled when changes are made to the database files.<br />
