This type of gold deposit, formed mainly in the craton activation stage, occurred in the transitional period from a compressive regime of late or postcollision to an extension one.
For collinear collision, the preceding collision velocity and postcollision velocity are calculated on the basis of the impact locality and stop locality of collision vehicle.
对于二维碰撞,可以根据车辆的碰撞位置和停止位置,反推计算出车辆碰撞后的分离速度和碰撞前的接触速度。

Its petrology, petrochemistry and geochemistry feature show the intrusive is post - collision and strongly - peraluminous granite.
