摘要
近年来,随着流体包裹体研究进展.发现越来越多的矿床在成矿过程中曾发生过热液沸腾。本文试从热液沸腾产生机理出发,讨论氢氧同位素分馏行为。1.
In the paper,the author discusses the hydrogen and oxygen isotopic fractionation behaviour in the boiling process of hydrothermal solution and establishes the model for isotopic Rayleigh fractionation,isotopic dynamic fractionation and mixed solution with meteoric water in closed and open systems.The hydrogen and oxygen isotope change regularity of Dachang, Shizhuyuan,Jinniushan,Piaotang,erc,ore deposits are explained and the possible existing of Rayleigh fractionation and mixing with meteoric water in the boiling process of hydrothermai solution comes to a conclusion.
