岩石颗粒解离试验研究

DISAGGREGATION OF GRAINS IN ROCKS

试验确定,在用HCl和NaOH试剂解离硅质胶结的沉积岩时,浓度5％的试剂即可达到解离度95％以上,且颗粒表面特征、重矿物数量和重矿物标型特征较浓度10％的试剂处理的样品保存得更好。

Based on the experiment this paper shows that hydrochloric acid and sodium hydroxide with a concentration of 5 percent (instead of 10 percent) can be used for disaggregation of sedimentary rocks cemented by silicon. The degree of disaggregation of rocks is more then 95 percent. The preservation of surface of grains and the quantity and typomorphic characteristics of heary minerals are much better than those of the grains disaggregated with the solution of 10 percent in concentration.
