| 摘 要： | 自泥盆纪以来,西成古盆地发生了一系列构造-岩浆热事件:初期为海盆内部结构的形成和演化,随之是沿边缘转换断层分布的古地热异常区的形成及热水沉积同生成矿作用的发生;随后的热事件主要为热变质作用,动热变质作用,岩浆的侵入与侵位,变形及退变质作用,构成了本区的热历史。

| Abstract: | Since the Devonian, a series of tectonic-magmatic heat events have taken place in Xicheng paleobasin. In the early days, inner structure of the basin was formed and evolved. Afterwards the geothermal anomalies formed and syngenetic hydrothermal-sedimentary metallization happened along the margin transform fault. After this the heat events in the area occurred successively:thermal metamorphism,dynamothermal metamor-phism, intrusion of magma, deformation and degeneration, etc. |
