This paper deals with the principles and methods of systematic inverse medeling. The writers describe and introduce how to use inverse modeling for magmatic fractional crystallization using trace elements, minimization solution in minimum sense and evaluation of preferred model parameters for igneous samples. The writers draw up a computer program in fortran language executived in IBM-PC type computcr. Imitative and measured data have then been chceked for inverse modeling program. After the process nature has been defined for a suite of samples, inverse modeing could be done for certain selected trace elements. This method will be more rdiable and effective for understanding of magmatic process compared with empirical or forward modeling.
