浅论黄玉的成因与成岩-成矿模式

根据含黄玉岩石的矿物学、地质和地球化学以及黄玉中的流体包裹体特征研究，借鉴富F酸性岩体系的成岩成矿实验新成果，推出了新的黄玉成岩-成矿模式，力证黄玉是以富氟低熔岩浆结晶为主的多成因产物，不否定黄玉的交代蚀变和变质成因，认为盲目滥用和过分夸大变质（含交代）作用及其成岩、成矿的极端重要性和普适性不可取。

On the origin and rock- and ore-forming model of topaz

Recently, a theory which considers that topaz may crystallize directly and mainly from the F_rich acid magma and/or the F_rich magmatic_hydrothermal transition fluid similar to magma in overall nature has given a vigorous challenge to the traditional ideas of single alteration origin for topaz. The high_ultrahigh_pressure metamorphic topaz has been reported time and again. On the basis of geological, geochemical and mineralogical characteristics of topaz_bearing rocks as well as related petrogenetic and metallogenic experimental data, a new petrogenetic and mineral_forming model for topaz has been established. The model does not negate the alteration and metamorphic origin of topaz. The authors hold that it is inadvisable to emphasize the role of metamorphism (including alteration) indiscriminately and exaggerate its ubiquity and its importance to petrogenesis and mineralization.
