1·Very complex structures and characteristics of khondalite series were caused by poly phases of metamorphism and deformation.
由于多期强烈的变形变质作用，区内孔兹岩系的地层结构十分复杂。
2·The investigation of the khondalite sequence and its position in the stratum system of Archean in Daqingshan region is very useful to study the high-grade region of adjacent areas.
大青山地区所建立的孔兹岩地层层序及其在太古宙地层系统中的位置，无疑对相邻地区高级变质区的岩石地层研究有重要借鉴意义。
