详细研究了在金伯利岩中发现的金刚石晶体和多晶体后,就可发现在它们中间,可以见到具有一定标型特点(形态、结构、结晶化学、共生)的一些变种,这些变种彼此间是不同的,每一个变种都有其特殊的结晶条件。在一个金伯利岩筒中发现不同的晶体变种,证明在这种类型的矿床中,金刚石的成因是复杂的。关于金伯利岩中金刚石的成因,存在着许多假说。这些假说通常忽视了一个因素,即在每一个金伯利岩矿床中以不同的数量对比关系出现的金刚石结晶晶体和多晶的各种变种,不能在同样的条件下和由
After studying in detail the diamond crystals and polycrystals found in the kimberlites, it is found that among them there are some varieties with certain type features (morphology, structure, crystallochemistry, symbiosis) which are Different, each variant has its own special crystallization conditions. The discovery of different crystal variants in a kimberlite tube proves that the diamond causes are complex in this type of deposit. There are many hypotheses about the causes of diamond in kimberlite. These hypotheses generally ignore the fact that diamond crystals and polycrystalline variants occurring in different quantities in each kimberlite deposit can not be used under the same conditions and by
