迄今为止，微石香肠结构已被用于结构分析中，作为塑性应变的可靠度量，最近有人提出将其用作相对差应力的度量。本文论证了将应力和应变分析结合起来进行，可以同时推导出应力和应变。分析的样品是来自日本不同高P/低T型变质带的四个地点的石英片岩。这些样品包括在韧性石英基质中的微石结状的有竞争力的皮德蒙特颗粒。分析强烈表明，估计的差应力往往会随着应变的增加而增加，并在微石香肠的最后阶段，他们达到最大值。
Microboudin structure has so far been used in structural analysis as a reliable measure of plastic strain, and recently it has been proposed to use it as a measure of relative differential stress. This paper demonstrates that stress and strain can be simultaneously deduced if the stress and strain analyses are carried out in combination. The analysed samples are quartz schists from four localities of different highP/ lowTtype metamorphic belts in Japan. The samples include microboudinaged competent piedmontite grains within a ductile quartz matrix. The analyses strongly suggest that the estimated differential stresses tend to increase with increasing strain and that, at the final stage of the microboudinage, they reach a maximum.
