This paper consists of three parts. The first part describes the recongnization of search for uranium ore deposits in China. The second part provides in some detail the recongnized types of uranium deposits and characteristics of geological mineralization in China. The main types of uranium deposits are granite type, volcanic type, sandstone type and calcareoussiliceous-pelitie type. And it also analyses the close relationship between the time and space of uranium deposits formation and the redbeds of Cretaceous-Tertiary...

This paper consists of three parts. The first part describes the recongnization of search for uranium ore deposits in China. The second part provides in some detail the recongnized types of uranium deposits and characteristics of geological mineralization in China. The main types of uranium deposits are granite type, volcanic type, sandstone type and calcareoussiliceous-pelitie type. And it also analyses the close relationship between the time and space of uranium deposits formation and the redbeds of Cretaceous-Tertiary period. The formation of the granite-type-deposits in South China is closely related to tectonic block caused by palaeogeography, palaeoclimatology and Yanshan Movement. The activation, migration and redeposition in favourable terrains of uranium in uraniumrieh beds occurs. The third part makes a comparision of the recongnized uranium ore deposit types between China and the world. It apparently indicates that the uranium deposits in China are primaryly of granitic and volcanic-hydrothermal-vein type. Uranium orebodies mainly occur in Middle-Cainozoic terrain, palaeozoic terrain and the top part of Sub-Sinian terrain (the oldest). The age of uranium mineralization is generally less than 100m. y., However there are many types of uranium deposits in the world. The age of ore bearing beds may be old or young, however, the most important beds for uranium are of precambrian metamorphic rocks, in which the world well known uranium ore deposits of quartz-pebble conglomerate-type, uncomformity-vein-type and porphyry-type occur. Through the comparision we realized that we should strengthen our study of geological metallogenetic laws, compare our known uranium deposits with world known uranium deposits, enlarge the prospect areas of known deposits and study of new types of uranium deposits. In such a way we can enlarge increasingly uranium resources in China.

本文共分三部份,第一,簡述了我国鈾矿找矿的认识过程,第二,比較詳細地描述我国发现的鈾矿类型及其地质矿化特征,鈾矿床类型以花崗岩型、火山岩型、砂岩型和碳硅泥岩型为主。分析了鈾矿床的形成在时間上和空間上与白堊-第三系紅层的密切关系。华南花崗岩鈾矿床其形成是与白堊-第三系古地理气候和燕山运动产生的断块构造有关,使富鈾层位中的鈾产生活化,迁移,而于有利的部位再沉积;第三,把我国已发現的鈾矿床类型,同世界土鈾矿床相比較。我国鈾矿床以花崗岩型和火山岩型热液脉状矿床为主,含鈾层位主要是中新生代、古生代,最老的为震旦亚界的頂部层位,鈾矿化年龄一般小于100百万年。而世界上鈾矿床类型很多,含矿层位有老有新,而尤以前塞武系变質岩最为重要。世界上最著名的石英卵石砾岩型、不整合脉型以及斑岩鈾矿型等均賦存在此层位中。从对比中启示我們今后应加强地質成矿規律的研究,注意同国外已知类型进行类比,积极扩大已知类型的远景,探索新类型,以扩大我国鈾矿资源。

China is abundant in rare earth mineral jesources. The rare earth ore deposits and mineralization regions are regularly distributed both in geologic space and in geochronologic trme the RE mineral deposits are spreaded 'n stable region (platform of paraplatform) as well as in mobile region (geosyncline or fold system) In any geochronologic unit RE mineral deposits might be formed and, especially, in Hercynian and Yanshan movement they are mineralized in large scale and in vast area. On the bases of RE mineralized condition, the RE mineral deposits in China may be divided into ten genetic types as follows: 1, granities, alkali-granitic, grano-dioritic, and albitized granitie type; 2, alkaline rock type; 3, carbona tite type; 4, skarn type; 5, pegmatite type; 6, inetamorphic rock type and sedimentary-metamo-phic carbonate rock type; 7, hydrothermo-metasomatic and hydrothermal vein type; 8, sedimentary rock type; 9, rare earth placer; 10, deposits in weathered crust of granitic body. Any type mentioned above has its own real occured place

稀土矿床和稀土矿化地区在地质空间和地质时间的分布方面各有规律。空间上既分布于稳定地区(地台和准地台),亦分布于活动地区(地槽和褶皱系)。在地质时代方面,各造山运动和岩浆活动期都能够成矿,尤以海西期和燕山期矿化规模大,面积广。根据成矿条件,将稀土矿床划分为十种成因类型,即:1)花岗岩、碱性花岗岩、花岗闪长岩、钠长石化花岗岩型;2)碱性岩型;3)火成碳酸岩型;4)矽卡岩型;5)伟晶岩型;6)变质岩和沉积变质碳酸盐岩石型;7)热液交代和热液脉型;8)沉积岩型;9)稀土砂矿型;10)花岗岩类风化壳型。
