With some examples, the correlat ions between the thermal expansion coefficients of minerals and the types of cr ystal structures, the nature of chemical bonds, the valencies of ions , the interionic distances, the percentage ionic characters, the electronic conf igurations of ions and the chemical compositions are discussed and summarised . The crystal chemistry approach has been used in the calculation of the th ermal expansion coefficients for minerals with simple structures and composition s.

晶体化学方法是研究矿物热膨胀系数的有效方法,但由于矿物的热膨胀系数和晶体化学参数之间的定量关系尚未完全弄清,目前仅仅能对简单结构矿物的热膨胀系数进行计算,结构、成分较复杂的矿物的热膨胀系数计算尚缺乏好的晶体化学模型。

Meanwhile, they show high abundances of Sr and Ba and high Sr/Y and La/Yb. The volcanic rocks have varied and enriched Nd isotopic compositions ε(subscript Nd=-11~-17, which plot intermediately between the field of the ancient continental crust and the field of the enriched subcontinental lithospheric mantle. These geochemical signatures indicate that the volcanic rocks of the Tiaojishan and Donglingtai Formations were originated from a process of hybridization between the enriched mantle-derived mafic magma and the lower continental crust.

火山岩的钕同位素成分变化大,且相当富集ε(下标 Nd=-11~-17,都分布在古老下地壳和富集地幔之间,因此推断北京西山地区髫髻山组火山岩和东岭台组火山岩的形成与富集地幔起源的基性岩浆与古老下地壳组分相互作用有关。
