本文提出了一种利用方解石双晶数据计算机反演得到的偏应力张量确定主应力大小的新方法。垂直应力（覆盖层重量）或平均应力的附加估算足以计算完整的应力张量。我们强调，最好的推理包括结合方解石双晶分析与岩石力学数据（故障/摩擦标准），因为绝对应力张量的六个参数的确定是过度约束。
This paper proposes a new method for determining principal stress magnitudes, based on the use of the deviatoric stress tensor determined from computer inversion of calcite twin data. Additional evaluation of the vertical stress (weight of overburden) or of the mean stress is enough to calculate the complete stress tensor. We emphasize that the best reasoning consists of combining calcite twin analysis with rock mechanics data (failure/friction criteria), because the determination of the six parameters of the absolute stress tensor is overconstrained.
