垂直于最小主压应力方向上的应力场，在过去的几十年里，由于包括超大陆/古大陆重建在内的各种原因，在世界范围内得到了广泛的研究。印度的德干大火成岩省（DLIP）是裂隙喷发的产物，具有巨大的熔岩场和岩脉-岩床网络。DLIP与印度半岛的一些裂谷带有关，这反映了印度岩石圈中预先存在的弱点（图1）。在裂谷带喷发中，岩浆通常通过岩墙被输送到地表。然而，由于岩石力学的非均匀性和各向异性，一些注入岩脉没有到达地表，而是滞留在裂谷带的一定深度，或JU Wei，HOU Guiting和K.R.

perpendicular to the minimum principal compressive stress, which have been extensively studied in the world during the past decades for various reasons including the reconstruction of supercontinents/paleocontinents. Deccan Large Igneous Province (DLIP) of India is the product of fissure eruptions with vast lava fields and dyke-sill networks. The DLIP is associated with some rift zones of peninsular India, which reflect the pre-existing weaknesses in the Indian lithosphere (Fig. 1). In rift-zone eruptions, magma is normally transported to the surface via dykes. However, some injected dykes do not reach the surface but are arrested at certain depths in the rift zone due to the mechanical heterogeneity and anisotropy, or JU Wei, HOU Guiting and K.R.
