摘要

Tengchong 地热的区域,有经常的地震的一个活跃构造区域,位于西南的中国的云南省。这个区域包含丰富的活跃温泉,它经常显示高金属集中和明显的矿化作用现象。在 19:19 在 2009 年 7 月 9 日,地震发生在 Yao'an, Chuxiong,云南省,它是到 Tengchong 地热的区域的东北的 300 km。我们从 7 月 4 日在 Tengchong 区域在温泉取样了水到 2009 年 7 月 9 日并且从 7 月 10 日到 2009 年 7 月 15 日在地震前后学习元素的集中的变化并且在温泉的矿化作用上讨论地震的影响。大多数踪迹元素的集中稍微增加了,但是 REE (稀土元素元素) 的集中在一个趋势 NS 差错附近在温泉在地震以后在 50% 减少了。元素的集中在 Longtan 和 Suanshuigou 仍然保持未改变,它与一个不活跃的坑有关。在表面、小规模的差错控制的另外的弹簧的元素的集中在地震以后减少了。地震能刺激深差错和岩浆房间的活动,作为为沿着趋势 NS 深差错的温泉的金属集中的增加负责;而它能减少可渗透的岩石的孔,在与表面的差错有关的温泉导致忍受矿石的液体和相应矿化作用的流动的衰落。
