摘要
香港地区届华南加里东构造—岩相带南缘，中生代西太平洋岩浆活动带一部分。仅见中泥盆统、下石炭统、二叠系、浓罗系和山恶系。其中大面积分布的是中晚侏罗世火山岩系；燕山中晚期的花岗岩、花岗闪长岩、石英二长岩、长石斑岩等。区域构造是一复式背斜，轴向北东—南西。矿产以长石、白陶土和石英砂岩为主。奇岩界石众多，海蚀岩洞发育。
Hong Kong special district, located in the south margin of Caledonian tectonic-lithofacies belt, belongs to the part of west Pacific magmatic mobile belt of Mesozoic. Predevonian base-ment is unexposed in the district. Only few stratum of middle Devonian, lower Caboniferous,Permian, Jurassic and Cretaceous exposed while middle-lower Jurassic volcanic sequence is wide-ly distrihuted. Granite, Giranodiorite, adamellite, feldspathic, porphyry of middle-late Yanshan are well devoloped. There is an anticlinorium with the axial direction of northeast-southwest in the regional tectonics. The nlineral resources are dominated hy feldspar, porcellanite quartz sand.
