坪上一带深层次构造岩的变形特征及温压条件分析

Study on Deep-level Tectonites in Pingshang

摘要:

山东坪上一带深层次构造岩发育 ,依其塑性变形矿物及其组合、同构造新晶和同构造变形晶所反映的变形特征的不同可分为石英变形相构造岩、钾长石变形相构造岩和斜长石变形相构造岩 ,其变形时的温压条件为中压相系的低绿片岩相—低角闪岩相

Abstract:

Deep-level tectonites develope well in Pingshang area. According to plastic deformed minerals and their combination, defromed characteristics reflected by synorogenic new crystal and synogenic deformed crystal, they can be divided into quartz deformed tectonites, potash feldspar deformed tectonites and plagioclase deformed tectonites. The deformation temperature and pressure condition are from middle-pressure low greenschist facies to low amphibolite facies.
