Based on the detail studies of relationship between metamorphism and deformation of Mayuan Group (early Proterozoic) and Mamianshan Group (late Proterozoic)in Northern Fujian and P-T-t paths determinated from the zoned garnets, as well as the data of structural geology and isotopic geochronology, it is proved that the metamorphic rocks of Mayuan Group formed in early Proterozo.
本文通过对闽北麻源群和马面山群变质岩详细的变质变形关系的研究和石榴子石环带测定P-T-t轨迹的应用,结合构造地质和同位素年代学的资料,证实了麻源群变质岩形成于早元古代或更老年代,在早元古代末期遭受过中压、中高温变质,但在晚元古代晋宁期与中元古代形成的马面山群岩石一起经历了强烈的变质变形作用,表现为早元古代麻源群岩石遭受强烈改造,具有早期地壳再活化特点。

大陆碰撞带变质作用一般以顺时针p-T轨迹演化为特征,尤其伴有峰期变质之后的等温减压过程。
补充资料：趋势线
趋势线——
趋势线是用来衡量价格波动的方向的直线，由趋势线的方向可以明确地看出股价的趋势。在上升趋势中，将两个低点连成一条直线，就得到上升趋势线。在下降趋势中，将两个高点连成一条直线，就得到下降趋势线。上升趋势线起支撑作用，下降趋势线起压力作用，也就是说，上升趋势线是支撑线的一种，下降趋势线是压力线的一种。
