The magnetotelluric sounding(MT) simulated annealing inversion is a nonlinear and global optimization method. The main advantages of simulated annealing are: (1) inversion results not depending on the starting model; (2) reaching the global minimum; (3) not calculating the derivative matrix. This method has been applied into 1D magnetotelluric sounding data interpretation. The results of synthetic and field data indicate that simulated annealing is very powerful in the interpretation of 1D MT data.
