列举了与锡-钨矿床紧密伴生的两个花岗岩块在年龄、物质成分和地球化学特征等方面的新资料。指出了这两个花岗岩块不仅在稀有元素含量方面而且在造岩矿物和副矿物的成分方面都与外贝加尔、蒙古人民共和国、西部滨海地区及捷克斯洛伐克的标准稀有金属花岗岩十分相似。所研究的锡霍特山中部的晚白垩世稀有金属花岗岩,是从富含稀碱金属、挥发性元素和金属元素(Sn、W、Nb)的岩浆熔体中结晶出来的。花岗岩块具分带结构、该岩块周围存在接触晕,花岗岩的石英中含有熔融包裹体以及其他一些特征表明,所述花岗岩为岩浆成因。 锡-钨矿化与稀有金属花岗岩具有空间和成因上的联系 The new information on age, composition of matter and geochemical characteristics of two granite blocks closely associated with the Sn-W deposit is listed. It is pointed out that these two granite blocks are very similar to the standard rare-metal granites of the Outer Baikal, Mongolian People’s Republic, the western coastal areas and Czechoslovakia not only in terms of rare element contents but also in the composition of rock-forming minerals and accessory minerals. The Late Cretaceous rare-metal granites studied in the middle of the Mt. Sihuote are crystallized from a magma melt rich in dilute alkali metals, volatile elements and metallic elements (Sn, W, Nb). The granitic blocks have a zonation structure with contact halo around the block, the melt inclusions in the quartz of the granite and other features indicating that the granites are of magmatic origin.
