紅河斷裂帶

紅河斷裂帶是位於青藏高原東南緣的一條斷裂帶，被視為川滇塊體的西邊界^[1]。

地質背景

自新生代以來，隨着印度板塊持續向北楔入，青藏高原東南緣經歷了顯著的構造變形^[2]^[3]。紅河斷裂帶作為川滇塊體的西部邊界，不僅分隔印支塊體與華南塊體^[4]，還因青藏高原物質向東側擠出，成為區域內重要的深部構造帶^[5]^[6]^[7]。紅河斷裂帶的地質構造及地殼變形具有由北向南的分段特徵^[8]，其與峨眉山大火成岩省的岩石侵蝕程度相呼應^[9]。

地質構造特徵

紅河斷裂帶是中國最長的走滑斷裂帶之一，全長約1,000公里，斜貫雲南西部和南部，整體呈北窄南寬的形態^[1]。斷裂帶從洱源延伸至越南北部灣，被分為北段、中段和南段（北段為洱源—彌渡，中段為彌渡—大斗門，南段為大斗門—河口）^[8]。

中-晚二疊紀時期，紅河斷裂帶可能為峨眉山大火成岩省的岩漿活動提供了通道^[9]；而在古近紀，斷裂帶經歷了多次左旋走滑運動，隨着青藏高原的東向擠出，吸收了大量地殼縮短量^[10]^[11]。到了新近紀，紅河斷裂帶從左旋走滑轉變為右旋走滑運動^[12]。第四紀以來，斷裂帶以右旋走滑兼具伸展運動為特徵，其中中段呈現顯著的逆沖運動^[6]^[13]。

紅河斷裂帶兩側地殼厚度存在明顯差異，東側地殼厚度可達約50公里，而西側則僅為30公里左右^[1]。紅河斷裂帶北段的泊松比值較高，可能與地幔物質底侵有關^[14]^[15]；而南段的泊松比相對較低，表明以長英質為主的地殼成分更容易發生部分熔融^[16]。大地電磁資料顯示，北段存在高電導率體，表明該區域的地殼結構可能受到上地幔影響^[17]^[18]^[19]。

地震活動

紅河斷裂帶屬於中國南北地震帶的南段，地震活動具有顯著的分佈不均勻性^[1]。北段地震活動頻繁，歷史上發生過多次6級以上地震，其中包括2次7級以上大震；而中段幾乎無震，南段的地震活動則集中在東側的石屏—建水斷裂上^[20]^[21]。

紅河斷裂帶北段和中段北側具有發生大地震的潛力^[22]，而南段則可能孕育長周期的大地震^[23]。
