| 摘 要： | 本文以鞍山地区樱桃园——眼前山一带为例,讨论BIF型铁矿在韧性变形带中的转变,旨在阐明中低温韧性变形带中BIF型铁矿的矿物、化学成份和流体性质的演变;矿石层中组构的变化,特别是该类铁矿特征的条带状构造的演变;韧性变形带中变质与变形的关系及其对铁矿石质量的影响。韧性变形带中铁矿围岩的变化将一起讨论,以便对照说明。

| Abstract: | Three aspects are involved in transformation of the BIF-type iron deposit in Yingtaoyuan-Yanqianshan ductile zone under low to moderate temperature region in Anshan district. 1, the appearance of new mineral phase transfers the type of the iron ore; 2,the deformation and recrystallization of minerals and the diffusive differentration tranfers the fabrics of the iron ore; 3, the metasomatism resulted from the incoming of fluid outside the ductile zone transfers the chemical composition of the ore.This paper discusses the above three transformations in detail ways affect the quality of iron ore in ductile zone have been summarized. |
