TsNIGRI MNR, Moscow, Russia, [email protected] Summary. Fluid inclusions were studied in quartz from Au deposits of two types found in the Central Kolyma region of the NE Russia, namely, from metamorphic-hydrothermal Auquartz deposits (Natalka, Verkhny Khakchan, Yugler, Degdekan, and Tokichan deposits), and from intrusive-related Au-sulfide-quartz deposits (Dubach, Pauk, Tautedzhak, and Chumysh deposits). Deposits of various types differ in fluid inclusion compositions and PTX characteristics. These characteristics can be used as an assessment criteria at early exploration stages, particularly in revealing sources of gold placers. ɐɟɧɬɪɚɥɶɧɨ-Ʉɨɥɵɦɫɤɢɣ ɪɟɝɢɨɧ (ɐɄɊ) ɩɪɟɞɫɬɚɜɥɹɟɬ ɫɨɛɨɣ ɧɚɢɛɨɥɟɟ ɛɨɝɚɬɭɸ ɦɟɬɚɥɥɨɝɟɧɢɱɟɫɤɭɸ ɨɛɥɚɫɬɶ ɜ ɩɪɟɞɟɥɚɯ əɧɨ-Ʉɨɥɵɦɫɤɨɣ ɡɨɥɨɬɨɪɨɫɫɵɩɧɨɣ ɩɪɨɜɢɧɰɢɢ. ȼ ɩɨɫɥɟɞɧɢɟ ɝɨɞɵ ɐɄɊ ɩɪɢɨɛɪɟɬɚɟɬ ɱɟɪɬɵ ɡɨɥɨɬɨɪɭɞɧɨɝɨ ɪɚɣɨɧɚ ɦɢɪɨɜɨɝɨ ɤɥɚɫɫɚ ɫ ɩɪɟɨɛɥɚɞɚɸɳɢɦ ɤɪɭɩɧɨɬɨɧɧɚɠɧɵɦ ɬɢɩɨɦ ɦɟɫɬɨɪɨɠɞɟɧɢɣ, ɤ ɱɢɫɥɭ ɤɨɬɨɪɵɯ ɨɬɧɨɫɢɬɫɹ ɨɞɧɨ ɢɡ ɤɪɭɩɧɟɣɲɢɯ ɜ Ɋɨɫɫɢɢ ɡɨɥɨɬɨ-ɤɜɚɪɰɟɜɨɟ ɦɟɫɬɨɪɨɠɞɟɧɢɟ ɇɚɬɚɥɤɚ (ȼ.ȼ.Ɋɭɞɚɤɨɜ, Ɇ.ɉ.Ʉɚɡɢɦɢɪɨɜ, ɋ.Ⱥ.Ƚɪɢɝɨɪɨɜ, 2004), ɚ ɬɚɤɠɟ ɪɹɞ ɟɝɨ ɚɧɚɥɨɝɨɜ − ȼɟɪɯɧɢɣ ɏɚɤɱɚɧ, Ⱦɟɝɞɟɤɚɧ ɢ ɞɪ.
