摘要

摘要利用电子反向散射衍射法研究了各种形态的金刚石晶体，包括碳化物。研究发现了不同性质的不均匀性：互穿和机械孪晶、非相干互生和分裂生长。不同类型的不均匀性在边界角分布模式上存在差异：互生主要是离散的，巴拉斯钻石的低角度边界是连续分布的，而碳多是连续随机分布的。研究表明，金刚石中的玫瑰沟道是机械孪晶交汇处蚀刻的结果。所揭示的机械孪晶厚度为 60-600 纳米。

Diversity of the Structure of Diamond Crystals and Aggregates: Electron Backscatter Diffraction Data

Abstract

Diamond crystals of various morphological types, including carbonado, were studied by the electron backscatter diffraction method. Cases of inhomogeneities of different natures were revealed: interpenetrant and mechanical twins, incoherent intergrowth, and splitting growth. Differences in the distribution pattern of boundary angles for different types of inhomogeneities have been shown: predominantly discrete in intergrowths, continuous distribution of low-angle boundaries in ballas diamonds, and continuous random distribution in carbonado. It has been shown that Rose channels in diamond arise as a result of etching at the intersection of mechanical twins. The revealed mechanical twins have a thickness of 60–600 nm.

期刊介绍： Geology of Ore Deposits is a periodical covering the topic of metallic and nonmetallic mineral deposits, their formation conditions, and spatial and temporal distribution. The journal publishes original scientific articles and reviews on a wide range of problems in theoretical and applied geology. The journal focuses on the following problems: deep geological structure and geodynamic environment of ore formation; distribution pattern of metallogenic zones and mineral deposits; geology and formation environment of large and unique metallic and nonmetallic deposits; mineralogy of metallic and nonmetallic deposits; physicochemical and isotopic characteristics and geochemical environment of ore deposition; evolution of ore-forming systems; radiogeology and radioecology, economic problems in exploring, developing, and mining of ore commodities.
