鸡血石“走血”之迷新探索

New Probing into “Blood-Losing” in Chicken-Blood Stone

摘要: 鸡血石的“走血”主要与辰砂中所含的 Fe,Zn,Se等微量组分有关。这些组分在氧化条件下与吸附于辰砂粒间的 Hg和 S等发生化学反应生成黑辰砂 ,因而使鲜艳的“鸡血”由红变暗 ,发生“走血”现象。如果鸡血石原生矿形成后 ,经过地表的风化作用 ,酸性溶液淋滤掉其中的 Fe,Zn,Se等微量组分 ,使单质汞易于向红辰砂转变 ,从而使“血”色鲜艳、稳定 ,不易“走血”。

Abstract: The phenomenon of "blood-losing" in chicken-blood stone is mainly due to Fe, Zn and Se. Under oxidation condition, these elements will react with Hg and S which are absorbed in cinnabar particles to produce black cinnabar. This makes the colour of "blood" become darker and darker(so called "blood-losing"). After weathering, the primary chicken-blood stone deposit loses Fe, Zn, Se, ect, owing to leaching of the acid fluid. It makes Hg change into red cinnabar easily, thus the colour of "blood" becomes more stable and brighter, uneasy to lose "blood".
