众所周知,与地球样品不同,陨石样品的研究难度较大。但随着测试手段的不断改进,近代陨石矿物学研究的进展甚为迅速。在陨石矿物的数量上和成因矿物学方面都取得了很大成绩。 1.陨石矿物数量到1983年为止,陨石矿物总数为140个左右(不包括陨石在大气层坠落时所形成的次生矿物),其中以各种硅酸盐矿物、合金矿物、硫化物和氧化物较为常见。非金属矿物几乎是金属矿物数量的两倍。根据初步统计仅存于陨石样品中而在地球上尚
As we all know, different from the Earth’s samples, meteorite samples are more difficult to study. However, with the continuous improvement of testing methods, the progress of modern meteorite mineralogy is very rapid. Great achievements have been made both in the number of meteorites and in the genesis of mineralogy. 1. The number of meteorite minerals Until 1983, the total number of meteorite minerals about 140 (excluding meteorites fall in the atmosphere when the formation of secondary minerals), in which a variety of silicate minerals, alloying minerals, sulfide and oxides More common. Non-metallic minerals are almost twice as many as metallic minerals. According to the preliminary statistics only exist in meteorite samples on the earth Shang Shang
