硼同位素分馏的实验理论认识和矿床地球化学研究进展
发布时间：2022-12-18 20:47
硼是一种中等挥发性元素,具有11B和10B两个稳定同位素。两个同位素间高达10%的相对质量差使其在地质过程中引起高达-70‰至+75‰的硼同位素变化。硼在自然界主要与氧键合形成三配位（BO3）和四配位（BO4）结构,因而11B和10B间同位素分馏主要受控于三配体（BO3）和四面体（BO4）间配分。本文综述了低温和高温地质过程的硼同位素分馏的理论和实验研究进展。在溶液中B（OH）3和B（OH）4-间硼同位素分馏受pH和热力学p-T条件控制,实验和理论表征获得常温常压条件下的B（OH）3和B（OH）4-间同位素分馏系数α3-4变化范围为1.019 4至1.033 3。低温条件下矿物（如碳酸盐、黏土矿物（蒙脱石和伊利石）、针铁矿、水锰矿、硼酸盐）与溶液间硼同位素分馏行为除了受p-T-pH影响外,矿物表面吸附引起...
