硼同位素分餾的實驗理論認識和礦床地球化學研究進展
發(fā)布時間：2022-12-18 20:47
硼是一種中等揮發(fā)性元素,具有11B和10B兩個穩(wěn)定同位素。兩個同位素間高達10%的相對質(zhì)量差使其在地質(zhì)過程中引起高達-70‰至+75‰的硼同位素變化。硼在自然界主要與氧鍵合形成三配位（BO3）和四配位（BO4）結(jié)構(gòu),因而11B和10B間同位素分餾主要受控于三配體（BO3）和四面體（BO4）間配分。本文綜述了低溫和高溫地質(zhì)過程的硼同位素分餾的理論和實驗研究進展。在溶液中B（OH）3和B（OH）4-間硼同位素分餾受pH和熱力學p-T條件控制,實驗和理論表征獲得常溫常壓條件下的B（OH）3和B（OH）4-間同位素分餾系數(shù)α3-4變化范圍為1.019 4至1.033 3。低溫條件下礦物（如碳酸鹽、黏土礦物（蒙脫石和伊利石）、針鐵礦、水錳礦、硼酸鹽）與溶液間硼同位素分餾行為除了受p-T-pH影響外,礦物表面吸附引起...
