野外调研及室内分析表明，秦岭杂岩中存在侧向变质分带．并曾发生侧向物质流动，侧向变质分带于晚加里东期冻结，侧向展市的硅线石－白云母带和硅线石－钾长石带的形成温压条件分别为５７９～５８４℃和５１７～５４３ＭＰａ及６８５～７２４℃和５３５～６２７ＭＰａ，晚加里东期秦岭杂岩的侧向物质流动导致了侧向变质带的形成。
Field research and laboratory analysis show that there are lateral metamorphic zones in Qinling complex. Lateral metamorphic zonation took place in the late Caledonian period. The temperature and pressure conditions of the sillimanite-smectite and sillimanite-k-feldspar belt in the lateral show were 579 ~ 584 ℃ and 517 ~ 543MPa and 685 ~ 724 ℃ and 535 ~ 627MPa, late Late Caledonian Qinling complex lateral flow of material led to the formation of lateral metamorphic belt.
