| 摘 要： | 通过对钛氢化物和钛合金氢化物的形成条件及理化特征、钛矿物的价态及化学成分、钛矿物的共伴生矿物组合、有关矿物中钛的固态包裹体及流体包裹体气相成分的研讨,考虑到氢在地球形成演化中的作用与重大贡献,认为:钛氢化物、钛合金氢化物是钛的重要迁移形式,它们随岩浆、热液从地球深部迁移至地球浅部,在较还原环境形成自然钛、低价钛矿物,在较氧化环境形成钛的高价矿物,并可在有利部位富集形成钛矿床。

| Abstract: | Conditions for formation of titanium and metal-combined titanium hydrides and their physicochemical characteristics, valence state and chemical composition of titanium minerals and their coexsisting and accompanying mineral associations, and vapor-phase composition of titanium's solid and fluid inclusions, all this has been brought into so a thorough investigation and study as to hold that titanium and metal-combined titanium hydrides stand as important carriers for titanium movement. They moved with magma and hydrothermal solution from the deep part of the crust to the shallow part to for natural titanium and low-valence titanium minerals under relatively reducing conditions, high-valence titanium minerals in more oxidzing domain, and even titanium deposits in favorable sites. |

| Keywords: | titanium hydride metal-combined titanium hydride movement mode geochemical model. |
