以洛南-栾川断裂、商丹板块缝合带和勉略板块缝合带为界，从北到南将研究区依次划分为：华北板块南缘构造岩浆区（简称SC岩区）、北秦岭构造岩浆区（简称NQ岩区）、南秦岭构造岩浆区（简称SQ岩区）、西秦岭构造岩浆区（简称WQ岩区）。依据各构造岩浆区内碰撞及碰撞后侵入岩的化学成分及出露面积，估算了各构造岩浆区及整个研究区碰撞及碰撞后侵入岩的平均化学成分。研究结果表明，各构造岩浆区碰撞及碰撞后侵入岩的平均化学成分相当于花岗岩；由南向北碰撞及碰撞后侵入岩微量元素含量的变化规律类似于区域地壳元素丰度的变化规律．从早到晚．从西向东碰撞及碰撞后侵入岩岩浆朝着富硅、富碱方向演化，逐渐显示出A型花岗岩的特点。
Taking the Luonan-Luanchuan fault, the Shangdan plate suture zone and the Mianli plate suture zone as bounded by the study area from north to south, the study area is divided into: structural southern margin of North China Plate (SC rock area), North Qinling structure Magmatic area (NQ rock area), South Qinling tectonic magma area (SQ rock area) and western Qinling tectonic magma area (WQ rock area for short). Based on the chemical composition and the exposed area of the intrusive rocks after collisions and collisions in each structural magma area, the average chemical compositions of the intrusive rocks after collisions and collisions in each structural magma area and the entire study area are estimated. The results show that the average chemical composition of intrusive rocks after collision and collision in each tectonic magma zone is equivalent to that of granite. The variation of trace elements in intrusive rocks from south to north collisions and collisions is similar to that of regional element abundances. From morning till night From the west to the east after the collision and collision, the intrusive rocks evolve toward the silicon-rich and alkali-rich areas, and gradually show the characteristics of A-type granites.
