#$%^&*AU2020101161A420200730.pdf#####Abstract This invention discloses a method for preparing the in-situ dating sample of the baddeleyite in basic-ultrabasic rocks, which comprises: divide the basic-ultrabasic sample on the described thin sections into multiple sub-regions; coat conductive material onto the described thin sections; find the Zr element in the basic-ultrabasic sample with SEM-EDS, and obtain the Zr elemental maps; navigate the position of the Zr element peak in the basic-ultrabasic sample under the SEM to the visible field; determine the position of the baddeleyite mineral in the basic-ultrabasic sample in the visual field; mark the position of the described baddeleyite mineral on the basic-ultrabasic rock sample; and drill out the marked described mineral baddeleyite. The invention can solve the difficulty of separating baddeleyite from basic-ultrabasic rock.Drawings A C E Region 1 Region 2 Region 3 Region 4 Region 5 B D F Figure 1 1/1
