中文摘要
PIS建议应用硼同位素研究来阐明块状硫化物矿床(Kidd Creek和Broke Hill)的矿化作用。他们开发了新的质谱学方法来提高分析精度,并进行了充分的前期工作,以表明硼是此类矿床中流体演化的有价值的踪迹。这项工作是新颖的,对成矿流体的来源和流体-岩石相互作用的过程具有新的洞察力。
英文摘要
The PIs propose application of boron isotopic studies to elucidate mineralization at massive sulfide ore deposits (Kidd Creek and Broken Hill). They have developed new mass spectrometric methods for improving analytical precision, and carried out sufficient preliminary work to show that boron is a valuable trace of fluid evolution in such deposits. The work is novel and holds potential for new insights into the source of mineralizing fluids and processes of fluid-rock interaction.
