广东省境内广泛分布着花岗岩,其分布面积约占全省陆地面积的40％。其岩种繁多,有大小岩体近两百个,有混合花岗岩、眼球状片麻岩和粗粒斑状花岗岩等等;它的产出有面积超过5000平方公里的大岩基、也有小岩体、小岩株,甚至厚度仅几米的岩脉等;在粤北、粤西北和粤东大岩基构成了海拔1000米以上的高山竣岭,在粤中和粤西沿海则多组成中低山和丘陵。广东地处亚热带,长期在外营力作用下,这些岩体表面均覆盖着一层较厚的风化土,目前这些风化土区已兴建了不少水利水电工程,如松涛水库、高州水库等。 Granite is widely distributed in Guangdong Province, its distribution area accounts for about 40% of the province’s land area. Its rock variety, there are nearly two hundred rock size, mixed granite, eye gneiss and coarse granuloid granite and so on; its output has an area of ​​more than 5000 square kilometers of large rocky, but also small rock mass, Small rocks, and even a few meters in thickness of the dikes; in northern Guangdong, northwestern Guangdong and eastern Guangdong big rock formations constitute 1000 meters above sea level Jun Ling, in Guangdong and western Guangdong are more composed of hilly and hilly. Guangdong is located in the subtropical zone. Under the long-term external operational force, the surface of these rock mass is covered with a thicker layer of weathered soil. At present, many water conservancy and hydropower projects such as Songtao Reservoir and Gaozhou Reservoir have been built in these weathered soils.
