N2 - The composition and mineral associations of amphiboles from marbles of the Luk Yen deposit of colored stones, northern Vietnam have been investigated. It was found that in ruby-bearing marbles, amphiboles are found in association with tourmaline, anorthite, phlogopite and are represented by pargasites and sadanagaites. Moreover, they are enriched in light lithophilic elements (Li, Be, B, K), fluorine, transition metals (Ti, Fe, Cr) and Ga and have more fractionated REE spectra relative to amphiboles from spinel-bearing marbles. At the same time, the latter are associated only with forsterite, clinohumite, and graphite and, in terms of chemical composition, belong to the tremolite-pargasite group. They are characterized by increased contents of V, Rb, Sr, Y, and REE and less fractionated distribution spectra of rare earths. The totality of the obtained data suggests that the formation of ruby-mineralized marbles took place not at the regressive, but at the progressive stage of metamorphism.
