Elastic thermobarometry can be used to constrain the pressure and temperature conditions of mineral crystallization by exploiting the difference in the elastic evolution of a mineral inclusion and its host during cooling and decompression. In this work we examine the pressure‐temperature sensitivity of >5,000 untested inclusion‐host pairs. Hosts such as diamond and zircon are ideal host minerals because their low compressibility makes them rigid containment vessels. Highly compressible inclusions such as albite, graphite, and quartz serve as the most reliable barometers. We provide three case studies of inclusion‐host pairs from different geologic settings to demonstrate the advantages and challenges associated with these mineral pairs. Apatite inclusions in olivine from Yellowstone caldera mostly record negative residual pressures (tension) and suggest magmatic crystallization at ~0.4 GPa. Rutile inclusions in garnet from Verpeneset eclogites record near ambient conditions and do not recover reasonable metamorphic conditions of rutile entrapment. These results suggest that stiff inclusions may have a tensile strain limit, a possible limitation of elastic thermobarometry. Albite inclusions in epidote from a blueschist (Syros, Greece) record geologically reasonable entrapment pressures, but a large range of residual pressures that may be caused by the complex anisotropy of both phases. Our theoretical and applied results indicate that elastic thermobarometry has the potential to be used to understand petrologic processes in diverse geologic environments, including mantle, metamorphic, and magmatic settings but that each elastic thermobarometer requires careful evaluation.

弹性热压法的应用和局限性：包含－主体对的弹性建模和实例研究的启示

通过利用矿物包裹体及其主体在冷却和减压过程中的弹性演化差异，弹性热压法可用于约束矿物结晶的压力和温度条件。在这项工作中，我们检查了超过5,000个未经测试的夹杂物-主体对的压力-温度敏感性。诸如钻石和锆石之类的基质是理想的基质矿物，因为它们的低可压缩性使其成为坚固的密闭容器。高度可压缩的夹杂物（如钠长石，石墨和石英）是最可靠的气压计。我们提供了三个案例研究，这些案例来自不同地质背景的夹杂物-宿主对，以证明与这些矿物对相关的优势和挑战。黄石破火山口中橄榄石中的磷灰石夹杂物大多数记录为负残余压力（张力），并表明岩浆结晶在〜0.4 GPa处。Verpeneset榴辉岩中石榴石中的金红石内含物记录在接近环境条件下，无法恢复金红石截留的合理变质条件。这些结果表明，硬质夹杂物可能具有拉伸应变极限，可能是弹性热压法的极限。来自blueschist（Syros，希腊）的附子中的bitbit夹杂物记录了地质上合理的包裹压力，但是很大范围的残余压力可能是由两相的复杂各向异性引起的。我们的理论和应用结果表明，弹性热压法有可能被用于理解包括地幔在内的各种地质​​环境中的岩石过程。
