| 摘 要： | 选择有大量次生方解石沉淀的海底蚀变玄武岩为研究对象,研磨、均一化后将粉末样品分为49份,其中48份分别以0.25,0.5,1.0,1.5,2.0,2.5 mol/L 6种浓度的足量HCl溶解0.5,1,2,4,8,16,32,64 h,选取溶解残渣测定其主要氧化物和特征微量元素含量,研究确定HCl溶解法去除海底玄武岩中次生组分的浓度—时间组合。结果表明,1.0 mol/L-0.5 h,1.0 mol/L-1 h,1.0 mol/L-2 h,1.0 mol/L-4 h,1.5 mol/L-0.5 h,1.5 mol/L-1 h,2.0 mol/L-0.5 h,2.0 mol/L-1 h和2.5 mol/L-0.5 h等9种HCl浓度—时间组合是可供去除海底蚀变玄武岩中次生碳酸盐的理想方案。

| Abstract: | Altered submarine basalts with rich secondary calcites were graded, homogenized, and divided into 49 subsamples. 48 subsamples were leached with hydrochloric acid (HCl) of different concentrations (0.25 mol/L, 0.5 mol/L, 1.0 mol/L, 1.5 mol/L, 2.0 mol/L, 2.5 mol/L) for different time periods (0.5 hour, 1 hour, 2 hours, 4 hours, 16 hours, 32 hours and 64 hours). The main oxides and trace elements in the leached residuals were analyzed to determine the preferred HCl concentration-time combinations for leaching secondary components in altered submarine basalts. The result indicates that there are 9 optimal schemes as preferred HCl concentration-time combinations to leach secondary components in altered submarine basalts, which are 1.0 mol/L-0.5 hours, 1.0 mol/L-1 hour, 1.0 mol/L-2 hours, 1.0 mol/L-4 hours, 1.5 mol/L-0.5 hours, 1.5 mol/L-1 hour, 2.0 mol/L-0.5 hours, 2.0 mol/L-1 hour and 2.5 mol/L-0.5 hour. |
