侵入体中发育哪些原生破裂构造？
参考答案：
根据原生破裂构造与流动构造的关系，将其划分为横节理、节理、层节理、斜节理、边缘张节理、边缘逆断层等。横节理又称Ｑ节理，节理面垂直于流线，也垂直于流面，裂面粗糙，属张节理性质；纵节理，又称Ｓ节理，节理面垂直于流面，平行于流线，较陡，裂面粗糙，亦可能属张节理性质；层节理，又称Ｌ节理，节理面平行于流面，也平行于流线，一般发育于侵入岩体的顶部，多数产状平缓，往往志侵入岩体顶部的接触面平行，故能概略地指示侵入岩体顶部接触面的产状。斜节理，又称Ｄ节理，与流线、流面斜交的两组共轭剪节理。边缘张节理，发育于侵入岩体陡立的边缘接触带，并常延伸到围岩中。节理面向岩体中心倾斜，常呈雁行式排列。边缘逆断层，与边缘张节理相似，发育于侵入岩体陡立的边缘接触带，向岩体中心倾斜，呈斜列式排列。

| A little boy invited his mother to attend his school's first teacher-parent meeting. To the little boy's 1 , she said she would go. This 2 be the first time that his classmates and teacher 3 his mother and he felt ashamed of her 4 .
