摘要
锆石在地壳三大类岩石,陨石和陨击岩中均有广泛分布,是最重要的副矿物之一。锆石的各种标型特征(特别是成分和形态)具有十分重要的矿物岩石矿床成因和地质找矿意义。本文还论述了用X射线法和晶形法求取晶体轴率的一致性,以及控制锆石晶形,延长度和颜色的主要因素。
Zircon distribution widety in the three main classes of rocks in earth's crust, the meteorite and the impactite. it is one of the most important accessory minerals. The author considers that the typomorphic features of zircon (among which the compositional features and morphological featurs are of greater significance) are especially conducive to letermining the genesis of a deposit and its prospect. This paper indicates also the uniformity in de(?)terminig the axial ratio of zircon crystals with X—ray diffraction method and goniometry method. It also refers to the main factors of controlling the colous, forms and ratios of length and width of zircon crystals.
