本文在新近陆续发表的几篇文章基础上,综合全部地质产状、岩化计算、光性测定及X射线粉末法与单晶分析结果,对安徽庐枞、浙江寿昌、桐庐及有关地区火山岩中碱长石的调制结构特征及其成因意义进行初步探讨。重点讨论分属扬子区与沿海区两大不同构造单元内火山岩中碱长石的出溶特征及地质成因问题。因此,凡涉及X射线单晶,透射电镜分析方法及调制结构衍射特征具体描述等已见于前文的诸细节,这里一般均从略。
Based on several recent articles published in this paper, based on the comprehensive geological occurrence, petrochemical calculation, photometric determination and X-ray powder analysis and single crystal analysis, the author studied the volcanic rocks of Luzong in Anhui, Shouchang in Zhejiang, Tonglu and other related areas Alkali feldspar modulation structure and its genesis of the significance of the preliminary study. This paper focuses on the dissolution characteristics and geological causes of alkali feldspar in volcanic rocks in two different tectonic units in the Yangtze area and the Yangtze area. Therefore, all the details related to X-ray single crystal, TEM analysis methods and the diffraction characteristics of the modulation structure have been found in the foregoing details, which are generally omitted herein.
