In Late Jurassic period (159-135Ma), when the orientation of maximum principal compressive stress was NW direction, the Wuzhangshan granite intruded to upward, accompanied the formation of NW trending Sanrenchang and Huangshuian breccia pipe belts; In the Early Cretaceous period (135-120Ma), when the orientation of maximum principal compressive stress was NNW trending, the second stage of Huashan granite intruded to upward, accompanied the formation of NW trending Qiyugou breccia pipe belts; In 120-105 Ma, when the orientation of maximum principal compressive stress changed to NE direction, the gold-bearing quartz veins and gold orebodies in breccia pipes were formed along the NE trending fractures; In the Middle Cretaceous period (105-85 Ma), when the orientation of maximum principal compressive stress was NEE, the NEE trending Leimengou granite porphyry intruded to upward, accompanied the formation of NEE trending Leimengou breccia pipe belts.

在晚侏罗世(159～135Ma)，构造应力场最大压应力方向为NW向，形成了NW走向的五丈山岩体以及NW向展布三人场、黄水庵两个角砾岩带；在白垩纪早期(135～120Ma)，最大压应力为NNW向，形成了花山岩体第二期上侵，并伴有NW向的祁雨沟角砾岩带；其后(120～100Ma)，构造应力场最大压应力方向变为NE向，形成了NE向含金石英脉及角砾岩体中金矿体；最后(100～80Ma)，形成了雷门沟花岗斑岩以及NEE向展布的雷门沟-杨河沟角砾岩带(区域构造应力场的最大主压应力方向为NEE向)。

A granitic rock composed of quartz and mica.

一种由石英和云母构成的花岗石。

Granitic rocks mainly consist of quartz, plagioclase and alkaline feldspar and hence have lower densities.

花岗质岩石主要由石英、斜长石和碱性长石组成，并因此具有较低的密度。

Its mineral composition may have different combinations of terms of feldspar, quartz-based, and granite is similar to "the granitic pegmatite."

其矿物成分可有不同的组合，若以长石、石英为主，与花岗岩相似，称"花岗伟晶岩"。
