| 摘 要： | 通过X光衍射、扫描电镜和能谱分析发现 ,琼北雷虎岭 -马鞍岭地区火山喷发物风化形成的次生黏土主要是球状和不规则球状富铁埃洛石 ,随着风化时间的增长 ,埃洛石的转变顺序为 10 埃洛石→ ( 10 + 7 )埃洛石→ 7 埃洛石 ,据此推测该地区火山喷发的先后顺序为雷虎岭东南→儒红村北→儒红村东。喷发年代在 6 0 0 0～ 12 0 0 0aBP之间

| Abstract: | It is well known that weathering process initiates as soon as the volcanic products reach the earth surface. As a result, various kinds of secondary clay minerals and their polytypes are formed in different periods of weathering process. Based on this fact, the time sequence and succession of volcanic eruption can be inferred. It may provide, therefore, a convenient dating method applicable to the prediction and assessment of volcanic hazards. In this paper, the weathering features of clay minerals from 3 |
