杨家湾原为一汞矿点，在前人工作基础上通过对杨家湾北东向含矿断裂带中部在夜郎组第一段（Ｔｌｙ１）和第二段（Ｔｌｙ２）中系统进行地球化学剖面取样，分析结果表明，仅１件样品Ｔ１含量低于１００×１０－６（ＹＪ１５ＴＩ含量为５６×１０－６）外，其余１４件（ＹＪ１～ＹＪ１４）Ｔｌ含量均大于１００×１０－６，变化于３８６～９６０×１０－６之间，平均为６５３×１０－６（０．０６５３％），达到铊矿石工业品位要求，与滥木厂铊（汞）矿床对比，在赋矿地层、控矿构造、围岩蚀变和矿化特征等方面均极相似，成矿条件有利，找矿远景良好，如进一步工作，有可能找到第二个滥木厂式铊矿床。
Yangjiawan was originally a mercury mine site. On the basis of previous work, the earth was systematically conducted in the middle of Yangjiawan northeast ore-bearing fault zone in Tly1 and Tly2 The results of chemical analysis showed that the contents of Tl in the remaining 14 samples (YJ1 ~ YJ14) were all higher than 100 × 10-6, except for the T1 content of one sample less than 100 × 10-6 (YJ15TI content of 56 × 10-6) , Varying from 386 to 960 × 10-6 with an average of 653 × 10-6 (0.0653%), which meets the requirements of industrial grade of thallium ore. Compared with thallium (mercury) deposit of the abortion plant, Ore control structure, wall rock alteration and mineralization features are very similar, favorable metallogenic conditions, good prospects for prospecting, such as further work, it is possible to find a second woodcut plant type thallium deposits.
