In terms of structural characteristics and geochemistry of the granites in conjunction with previous studies, we interpret that the garnet-bearing gneissic granite was formed during the collision between the Tianshuihai terrane and the Southern Kunlun terrane following the closure of a branch of the paleo-Tethyan ocean along the Mazha-Kangxiwa suture zone, the block hornblende-bearing granite was formed during post-orogenic extension. On the other hand, the granites of ca.

根据两个岩体的构造特征，结合前人的研究及地球化学特征，表明含石榴子石片麻状花岗岩形成于同碰撞造山时期，是甜水海地体与西昆仑南带晚古生代岛弧沿麻扎-康西瓦缝合带碰撞峰期的产物，代表了沿麻扎-康西瓦分布的古特提斯洋一个分支的闭合，而228 Ma块状含角闪石花岗岩形成于碰撞造山后的伸展背景。220～190 Ma持续发育的花岗岩是南昆仑地体拼合到北昆仑地体之后在其南部形成的新的深成岩浆弧带。

The reason that the micro spar the performance surpasses the natural granite, the marble, the synthesis stone and the artificial marble, contains the material ingredient and the formation with him related; The granite is by granulometric compositions and so on quartz, feldspar, mica.

微晶石之所以性能优于天然花岗石、大理石、合成石及人造大理石，与他所含的物质成分及成型有关；花岗石是由石英、长石、云母等颗粒组成。

Combined with the regional data the research indicates that (1) the Tianmenshan main body formed in the Middle Jurassic Epoch, whereas the minor body was the further differentiated and evolutive product of the main body;(2) in the Chongyi-Dayu-Shangyou ore concentrated area, the west of Gannan area, the diagenetic age and metallogenic age are basically concordant, and the mineralization concentrated during 150~155 Ma;(3) from the middle-plutonic granite intrusion to the hypabyssal granite-porphyry vein, the magmatic activities experienced only 1~5Ma, indicating there was the concentrated period of mineralization.

结合区域资料，研究表明：①天门山岩体的主体形成于中侏罗世，补体是主体进一步分异演化的产物；②在赣南西部的崇余犹矿集区内成岩与成矿的年龄基本上是协调一致的，成矿集中期为150～155 Ma；③岩浆活动由中深成相花岗岩侵入体演化到浅成相花岗斑岩脉仅相差1～5Ma，表明存在成矿集中期。
