东秦岭岩石圈热结构热状态十分不均匀，沿断面可分成华北地块、北秦岭、南秦岭、扬子地块四大块，南秦岭为“热区”，北秦岭为“冷区”。商丹断裂带具８１．３ｍＷ／ｍ２高热流值，是南北秦岭的分界线，是多期构造运动的活动带，是扬子地块与华北地块的缝合带。加里东期扬子地块向华北地块俯冲碰撞，印支—燕山期俯冲板片由于“去层状化作用”断开下沉，软流圈上侵，岩石圈上地幔变薄。后国华北岩石圈下部插入扬子俯冲板片中形成穿插构造，商丹断裂带成为现今向南倾的走滑断裂带。中上地壳有不同时期的大规模逆冲推覆体，断块向南叠置；下地壳缩短成“漏斗”状下滑，地壳增厚造成东秦岭造山带现今独特复杂的岩石圈五层结构模型。
The thermal structure of the East Qinling lithospheric thermal structure is very uneven and can be divided into four parts: the North China block, the North Qinling, the South Qinling and the Yangtze blocks along the section, the South Qinling as the “hot zone” and the North Qinling as the “cold zone”. The Shangdan fracture belt has a high heat flow value of 81.3mW / m2. It is the dividing line between North and South Qinling Mountains and is an active belt of multi-stage tectonic movement. It is a suture zone between the Yangtze block and North China block. During the subduction collision of the Caledonian Yangtze block to the North China block, the Indosinian-Yanshanian subducting slab discontinued subsidence due to de-stratification, and the asthenosphere invaded and the mantle became thinner on the lithosphere. The lower part of the northern part of the northern China lithosphere was inserted into the Yangtze subduction plate to form the interspersed structure, and the Shangdan fracture belt became the south-facing strike-slip fault zone today. The middle-upper crust has large-scale thrust nappe bodies of different periods, the fault blocks are superimposed to the south, the lower crust is shortened to a “funnel-like” shape, and the crustal thickening causes the unique and complex lithospheric five-layer structural model of the East Qinling orogen .
