各種不同的岩石,具有不同的构造特徵,为了研究上方便起見,我們對於這些不同的构造,分別給以不同的名稱,如層理、片理、節理、劈理等等,這些名稱常常不易明確地划分。因为它們都表示着岩石構造的共同特徵,那就是“能够沿着大致平行的方向劈開”的性質,可是每個名詞却分别代表不同物體或相同物體在不同條件下形成的種種性質。在含義上、形態上或成历上有着或多或少的區別,應該注意的是在某些方面有比較顯著的差别,而另一些方面却有着密切聯系,不能机械地分割,有的是在發展過程中從一個構造性質逐漸轉變為另一个構造性質,而給予了兩個名稱。因此,要想硬性地區別它們是不可能的。 1.解理——是矿物物理性質的一種特徵,礦物受外力 Different rocks have different tectonic characteristics. For the sake of convenience, we give different names to these different structures, such as bedding, lamination, jointing, cleavage, etc., which are often not easy Clearly divided. Because they all represent the common denominator of rock formations, they are “capable of cleaving in roughly parallel directions,” but each noun represents the different properties that different objects or the same object form under different conditions, respectively. In terms of meaning, there are more or less differences in morphology or history. It should be noted that there are significant differences in some aspects, while others are closely linked and can not be divided mechanically. Some are in the process of development In the gradual transformation from one tectonic nature to another tectonic nature, given two names. Therefore, it is impossible to distinguish them rigidly. 1. Cleavage - is a feature of the physical properties of minerals, minerals by external forces
