巖石標本的一些特點
1、常見巖石標本的一些特征,它們都有自己的一個特點相互區別。用深淺、噴出巖的形狀、結構的一個區別。
 
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來分類和鑒定,關鍵的分類是要抓住它的一個構造、結構組成的特征。觀察常見巖石標本的結構,從巖石的表面上是可以放映它的一個類型,像那些具氣孔、杏仁、流紋結構形狀是一般情況下是火成巖石中噴的巖類,具層理的結構與表面的構造是沉積巖類,對巖石結構仔細的觀察,將可以對巖石進行分類。
 
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、在用肉眼鑒定常見巖石標本時,經常會有一些礦物是難以便認定的,一般情況下只能根據它的色彩的深淺、堅硬的程度、比重的大小與鹽酸的化學反應,在來初步的判斷。可以從它的表面的光澤、透明度、條紋裂縫等,一些可以觀察的表面的現象,就可以進行下一步的判斷。
 
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.
