在大别山、贺兰山等地发现的网脉状微角砾岩与陨石撞击和隐爆火山活动无关, 也没有直接的断层位移联系, 表现为相对强硬的长英质结晶岩石中受张性或张剪性破裂网络控制、具黑色隐晶基质的角砾岩. 其公里尺度的规模、复杂的破裂组合关系、原地无序的围岩碎片, 尤其是化学成分与围岩接近一致的隐晶基质中无显著位移联系的超碎裂岩化作用, 以及可能的固态非晶质化变形性状等, 意味着该地区的深地壳岩石曾经发生了大规模、高能量的快速脆性破裂. Reticulated micro-breccia found in the Dabieshan and Helan Mountains have nothing to do with the meteorite implosion and implosion volcanic activity nor the direct fault-displacement association, which is characterized by the relatively hard and brittle rocks Sexual rupture network control, breccia with black cryptocrystal matrix, the scale of its kilometer scale, the complex fracture-assemblage relationship, the in-situ disordered surrounding rock fragments, especially the cryptocrystalline matrix whose chemical composition is close to that of the surrounding rock Free-fracturing lithologies with no significant dislocation, as well as possible solid-state amorphous deformations, mean that deep-crustal rocks in the area have experienced large-scale, high-energy, rapid brittle fractures.
