Titanite from the Late Paleozoic-Early Mesozoic granitic plutons of the northeast of Taimyr Peninsula are studied by EPMA and LA-ICP-MS. The composition of titanite corresponds to igneous mineral. The temperature and pressure of its formation are estimated. The composition of titanite is compared with indicators of porphyry mineralization. The granitic plutons are thus classified as to the possible presence of porphyry Cu-Au-Mo mineralization.
