The Lingshan Granite intruded into the strata of Sinian-Gambrian and Triassic ages. Isotopic age is 140—105 m.y. The main intrusive body is com-posed of the interior phase—coarse-grained porphyroid amphibole-bearing biotite granite, the transitional phase—coarse-grained Li-biotite monzonitiegr-anite, the marginal phase—medium to fine-grained Li-biotite monzonitic granite and the boss phase—medium to fine-grained zinnwaldite alkali-feldspar gra-nite. The evolution of the magma shows apparent regularity from early to late stage, from centre to border. This regularity is alike as the granite of the same type in South Ghina。There are lots of different rare-nonferrous metallic deposits around the inner and outer contact zones. According to de-veloping order of mineralization they are: granite type REE deposits, granite type deposits of Nb and Ta, pegmatite type deposits of Nb and Ta, greisen type deposits of W, Sn, fracture zone type deposits of Sn, skarn type deposits of Sn-polymetals, and quartz vein type deposits of W, Sn and polymetals. Being in different geological environments, the above-mentioned deposits form different associations in different tectonic settings.The minerogenetic series and association of ore deposits of the Lingsh-an Granite are typical of the same type granite of South China.

The uranium deposit No. 8411 is temporarily and spatially directly associated with the typical syntectic type quartz-syenite. The uranium deposit occurs in the Jurassic arkose sandstone being located in the exocontact zone of quartz-syenite intrusive body. The intrusive body is exposed in an area about 90 km~2. It may be divided into four intrusive stages according to the time of intrusion: biotitquartz-syenite; orthophyre; coarse to fine-grained quartz-syenite; porphyritic fine-grained quartz-syenite. Mineral composition of the ore is relatively complicated. Main uranium minerals include pitchblende, uranium black, metatorbernite, autunite, other minerals are various sulfides of Fe, Cu, Pb, Zn, Ni, Co, magnetite hematite, chalcedony and calcite, etc. The intrusive rock has moderate strontium initial ratio (~(87)Sr/~(86)Sr=0.707)characteristic of syntectic type granitoids. The time interval between the ages of host rock (130 m. y.) and ore deposition (108 m. y.) is small (<22 m. y.). Oxygen isotope study of the ore shows that the hydrothermal fluid responsible for the formation of the deposit is composed of magmatic water and meteoric water. δ~(34)S_(FeS2)=-2.3‰—+20.5‰(40 samples), δ~(34)S_(av).=+10.44%. These data indicate a mixed feature of sulfur in the hydrothermal fluid coming from the upper mantle and the crust. Results of gas-fluid inclusion study and thermometric calculation yield a temperature of the hydrothermal fluid about 100—300℃. The pitchblende has been formed between 170—200℃. The uranium and other metallic material of this deposit have been mainly differentiated from the quartz-syenite magma. The others have been drawn from the host rock. It is a meso-epithermal uranium deposit and has composite genesis. The mechanism of formation of uranium deposit No. 8411 is remarkably different from that of uranium deposits related to transformation type granitoids in South China.
