岩石标本的一些特点

1、常见岩石标本的一些特征，它们都有自己的一个特点相互区别。用深浅、喷出岩的形状、结构的一个区别。

 

1. some characteristics of common rock specimens are different from each other. a distinction between the shape and structure of the extrusive rocks in depth and shallowness.

 

2、人的眼睛也就是肉眼来分类和鉴定，关键的分类是要抓住它的一个构造、结构组成的特征。观察常见岩石标本的结构，从岩石的表面上是可以放映它的一个类型，像那些具气孔、杏仁、流纹结构形状是一般情况下是火成岩石中喷的岩类，具层理的结构与表面的构造是沉积岩类，对岩石结构仔细的观察，将可以对岩石进行分类。

 

2. the human eye is also the naked eye to classify and identify, the key classification is to grasp its structure, structure and composition characteristics. observing the structure of common rock specimens can show a type of rock from its surface, such as those with stomata, almond and rhyolite structure, which are usually erupted in igneous rocks. the stratified structure and surface structure are sedimentary rocks. careful observation of rock structure will enable us to see rocks. classification.

 

3、在用肉眼鉴定常见岩石标本时，经常会有一些矿物是难以便认定的，一般情况下只能根据它的色彩的深浅、坚硬的程度、比重的大小与盐酸的化学反应，在来初步的判断。可以从它的表面的光泽、透明度、条纹裂缝等，一些可以观察的表面的现象，就可以进行下一步的判断。

 

3. when identifying common rock specimens with the naked eye, some minerals are difficult to identify. generally, they can only be judged preliminarily according to the color depth, hardness, specific gravity and the chemical reaction of hydrochloric acid. from its surface gloss, transparency, stripe cracks, and some surface phenomena that can be observed, we can make the next judgment.
