    摘要:

    河南省地处秦岭造山带的东段,有着长达3.0Ga以上的构造演化历史,由于板块的俯冲碰撞作用,构造运动非常复杂,岩浆活动十分强烈。河南省不同类型、不同成因的花岗岩分布非常广泛。河南省花岗岩总面积超过1.45万km2,占全省面积的8.7%、基岩区面积的32.2%,占整个秦岭——大别山造山带花岗岩(面积为4万km2)的36.2%多,是中国著名的花岗岩密集区之一。河南省花岗岩及其不同的岩石类型很好地揭示和反演了东秦岭板块构造的每一个特定的构造演化阶段和岩浆动力学过程。河南省花岗岩的地质地貌也很具特色。以花岗岩为主形成的世界级、国家级及省级地质公园有6处之多,以花岗岩为主形成旅游的风景区多达二十多处,遍布河南全区。河南花岗岩地貌景观丰富多彩,具有雄、险、奇、幻的特征,各种景观形象逼真、千姿百态、栩栩如生、惟妙惟肖,河南省花岗岩地貌景观有九大类型,主要由内、外营力地质作用所造成。构造运动、花岗岩节理系统、岩石结构、水流冲刷、风化剥蚀等地质作用是造成河南花岗岩地貌景观的基本因素。河南省花岗岩地质地貌景观已成为一种新的重要自然资源,为人类文明和经济社会做出贡献。

    Abstract:

    Situated in the eastern segment of the Qinling orogenic belt, Henan Province has a tectonic evolution history of as long as more than 3 billion years. Because tectonic movements (plate subduction and collision) were very complex and magmatism was strong, granite of different types and origins are very well developed and very widely exposed. In Henan outcrops of granite over 14,5000km2, accounting for 8.7% of the total area of the province, 32.2% of the area of the bedrock area and over 36.2% of the granite area(40, 000km2) of the whole Qinling—Dabie orogenic belt; so Henan is China's famous region where granite is densely distributed. According to the Henan granite and its different rock types the authors well reveal and deduce backward each particular stage of tectonic evolution of the East Qinling plate and magmatic dynamic process. Study indicates that granite geomorphology in Henan is unique in its own way. Throughout Henan up to six statelevel and provinciallevel geoparks and more than 20 scenic spots with granite as the theme are distributed. The characteristics of the Henan granite landscapes may be summarized as four words: magnificent, precipitous, grotesque and fantastic. The geology and geomorphology of granite in Henan have been a new, important natural resource. Granite geomorphological landscapes in Henan may fall into nine types, which were mainly formed by internal and external geological agencies. Tectonic movements, granite joint systems, rock textures and structures, water erosion and weathering are basic factors responsible for the formation of granite landscapes. They have yielded significant economic benefits and made contributions to the human civilization, economy and society.
