变斑晶
1.
Porphyroblast inclusion trails are very useful in metamorphic geology or petrology and structural geology, which include orogenic models and their PTt paths, the relationship and history between metamorphism/deformation, shear sense and folding, porphyroblast growth rate, strain rate and strain, deformation degree and metamorphic grade, etc.
变斑晶晶内包体径迹在变质地质学和构造地质学中具有广泛的用途。
2.
The syntectonic porphyroblasts of pyrite and siderite in the ductile shear zone developed in epimetamorphic clastic rocks in Dabeiwu area are the products and marks of ductile shear deformation during progressive metamorphism.
大背坞地区浅变质碎屑岩内的韧性剪切带中发育有同构造成因的菱铁矿变斑晶和黄铁矿变斑晶，它们是进变质剪切变形的产物和标志。
3.
Porphyroblast is important media of relationship between deformation and metamorphism, so it is significant that geneses of structure,such as inclusion trails,in porphyroblast have been discussed widely and rigorously,because it is related to many aspects,such as folding machanism, p T t path,orogenic process or history,shear sense,and matter transport.
变斑晶晶内包体径迹的成因研究是当代变质岩岩石学研究的一个重大方向。
