结构分析的新进展

THE ADVANCES IN TEXTURAL ANALYSIS

岩石和矿石矿物的结构解释可追溯至显微术引入于岩石研究的初期，一个基本概念是结构以及以此为基础所引出的结论之间的对比。比较解剖学的原则已广泛应用于生物学，在岩石和矿石结构的解释中亦不失为一有力的工具。而且，结构分析尤其是追踪某一特定结构型式的发育，和生物科学中的组织学与比较胚胎学可相比拟，因而在岩石结构的解释中是十分有用的。基于结构分析作出的新解释可以导致岩石学传统观念的更新。对于花岗岩类及其它许多岩石，这点尤为正确。花岗岩类过去曾被认为是岩浆固结而成的岩石，然而基于结构分析，它们可以考虑为超变质作用的产物。

The interpretation of textures of rocks and ore minerals goes back to the dawnof rock microscope.A basic concept is the comparison of textures and the conclusions thatcan then be drawn.The principle of comparative anatomy,widely applicable in biology,isalso a tool for the interpretation of textures in rocks and ores.Furthermore,thermore,textural analysis.especially the following-up of the development of a particulartextural pattern,is comparable to histology and comparative embryology and is thereforemost useful in the interpretation of textures in rocks,Novel interpretations based on tex-tural analysis could lead to a reconsideration of orthodox petrology.This is particularitruefor granites and many other rocks,which in the past have been interpreted as magmaticconsolidation products and which on the basis of textural analysis,are considered to beproducts of ultrametamorphism.
