The present invention provides an analysis method for determining halogens in geological samples by ICP-MS. The method includes following steps: weighing a geological sample and ammonium bifluoride in a sample dissolving tank, tightening the sample dissolving tank, and shaking; then heating the sample dissolving tank in a drying oven, and setting a temperature of the drying oven as 200-220&#xb0; C. and heating time as 1-2 hours; cooling the sample dissolving tank to room temperature so as to obtain a solid mixture after heating is ended, adding ammonium hydroxide into the solid mixture, centrifuging, removing a precipitate, and collecting the supernatant; adding an internal standard solution into the supernatant, and uniformly mixing; and optimizing the ICP-MS to an optimal state, testing content of chlorine in the supernatant under a condition of medium resolution m/&#x394;m=4000, and testing content of bromine and iodine in the supernatant under a condition of low resolution m/&#x394;m=300.
