中文摘要：

本文通过对伏牛山构造带岩石的矿物岩石学、石英重结晶型式、石英分维值和有限应变等特征分析研究，认为伏牛山构造带的变质-变形深受洛南-栾川断裂带的影响，其变化有明显的规律性，从断裂带往北岩石从糜棱岩依次过渡为片岩-片麻岩-花岗岩原岩。构造带内发育多种糜棱岩，岩石变形强烈，远离构造带岩石的变形逐渐变弱。从构造带往北，石英的重结晶型式从SR向GBM变化，轴比逐渐变小，应变椭球体从长雪茄到扁椭球状，变形逐渐减弱，反映出构造应力从大到小的变化；沿构造带自西往东，石英重结晶型式由BLG型式到SR和GBM型式，分维数的变化等均反映出温度、构造应力逐渐增加，变质程度逐渐加深，塑性流变加强的特点。伏牛山构造带估算变质温度范围为300℃～520℃、应变速率值为4．11183E．15～3．68947E-17，属中-高温、中应变速率变质环境。靠近断裂带应变速率和构造应力大，远离断裂带逐渐减小，反映洛南-栾川断裂带较强的压扭性质。

英文摘要：

Based on mineral petrology, type of quartz recrystallization, quartz fractal dimension and finite strain analysis of Funiushan tectonic belt, the results showed that the characteristics of metamorphic-deformation in Funiushan tectonic belt changed in apparent regularity under the influence of Luonan-Luanchuan fault belt. Rocks from the fault zone to the north were in proper order：mylonite-schist-gneiss-granite. A variety of strong deformed mylonites were developed in the tectonic belt, the deformation of rocks generally weakened as them away from the tectonic belt. From tectonic zone to the north,the pattern of recrystallization of quartz changes from the SR to the GBM, the ratio of axial gradually become smaller, the shape of strain ellipsoid changes from long cigar to flat ellipsoid, and the deformation of rocks gradually weakened. These features reflect that tectonic stress changes from small to lager,the temperature changes from low to high. From west to east of the tectonic belt, the type of re-crystallization changes from dislocation glide-BLG to the SR and GBM pattern and the changes of fractal dimension reflects that temperature and tectonic stress increases gradually, grade of metamorphism gradually becomes deep and plastic flow is enhanced. Metamorphic temperature of Funiushan tectonic belt were estimated in the range of 300 ℃ -520 ℃,strain rate value of 4. 11183E-15 3.68947E-17. It belongs to high metamorphism temperature and medium strain rate environment. The strain rate and tectonic stress decrease as it far away from the fault belt. It reflects that Luo-Luan is a fault belt with strong compressoshear.
