In the present study, Paleozoic Variscan orogenesis was a model of the oroclinal flexion accompanied by extensive magmatism, which could be divided into the following two types: post-tectonic and syn-tectonic tonalite granite, and leuco-granite which were controlled by the tectonic characteristics of the intrusions. It was observed that a very high majority of the samples had displayed discontinuities in their structures, that were later utilized to define the granitoid morphology and development characteristics of the rock during the intrusion phases. Furthermore, it was determined that the tectonics associated with the Alpine orogeny results in the new generation of faults and fractures during the Paleogene Period had produced the development of the Sierras. Due to different weathering processes, the depressions which had resulted in the present granitoid reliefs were found to be exclusively related to the structural development processes during the geological history (either tectonic or magmatic) of the granite, and not as normally interpreted.

古生代的造山运动:西班牙伊比利亚半岛西北部花岗岩体的发育

在本研究中,古生代Variscan造山作用是伴随大量岩浆作用的口斜弯曲的模型,可将其分为以下两种类型:构造后构造的和同构造构造的方钠石花岗岩,以及由构造控制的白云质花岗岩。入侵的特征。可以观察到,绝大多数样品在结构上均表现出不连续性,后来被用于确定岩石在侵入阶段的花岗岩形态和发育特征。此外,已经确定,与古山造山运动有关的构造导致了古近纪时期新生代的断层和裂缝,导致了塞拉山脉的发展。由于风化过程不同,
