辽北清原地区在时空上有系统地发育了三个太古亩地体:浑河以南的小莱河花岗岩-绿岩带(XGGB)、浑河以北的清原花岗岩-绿岩带(QGGB)和在QGGB东北部出露的景家沟麻粒岩-片麻岩区(JGGR)。绿岩带中火山岩组合在XGGB中以双峰式岩套为特征,而在(QGGB中以连续的钙碱性系列为特征。XGGB中斜长角门岩全岩Sm-Nd等时线年龄为3018±20Ma,Nd(t)=+0.19±0.17,TDM=3347~3735Ma,而QGGB中的斜长角闪岩全岩Sm~Nd等时线年龄为2884±48Ma,∈Nd(t)=+2.61±0.41,TDM=2938~2992Ma。JGGR中黑云麻粒岩的Rb-Sr等时线年龄为2994±325Ma,可能代表变质年龄,表明其形成在XGGB之前。综合研究表明辽北地区太古亩地质演化模式很可能为:JGGB代表了古中太古代古陆的残骸,XGGB于中太古代形成在这个古陆边缘的裂谷盆地内,QGGB则形成在新太古代的大陆边缘岛弧环境,并于新太古代晚期与XGGB拼贴。在此陆一弧碰撞过程中,QGGB逆冲推覆于JGGR之上,后者由于后期的伸展作用而出露于地表。成矿作用是地质演化的组成部分,并受制于各个演化阶段的构造环境
The Qingyuan area in Northern Liaoning systematically developed three Swire Mud landforms in the space-time: Xiling River granite-greenstone belt (XGGB) to the south of Hunhe River, Qingyuan granite-greenstone belt (QGGB) to the north of Hunhe River, And Jingjiagou granulite-gneiss area (JGGR) exposed northeastern QGGB. The volcanic assemblage in the Greenstone Belt is characterized by a bimodal sleeve in XGGB and is characterized by a continuous calc-alkaline series in QGGB. The Sm-Nd isochron age of the whole rock in the XXGGB is 3018 ± 20Ma, Nd (t) = + 0.19 ± 0.17, TDM = 3347 ~ 3735Ma, while the Sm ~ Nd isochron age of the whole rock in QGGB is 2884 ± 48Ma, εNd (t) = + 2.61 ± 0.41, TDM = 2938 ~ 2992Ma. The Rb-Sr isochron age of 2996 ± 325Ma in JGRR may represent the age of metamorphosis, indicating that it formed before XGGB. It is probable that the geological evolution pattern of the Archean Taiw area in northern Liaoning is likely to be as follows: JGGB represents the remnant of the ancient Mesozoic Archean continent, XGGB formed in the rift basin on the edge of the ancient land in the Middle-Archaean and QGGB in the Neo-Archean continent Edge Island arc environment, and in the late Neo-Archean with X. GGB collage. During this land-arc collision, the QGGB thrusts over the JGGR, which is exposed to the earth’s surface due to later extension. Mineralization is an integral part of the geological evolution and is governed by The tectonic environment of evolutionary stage
