简 历:
杜治学,特任研究员,博士生导师,2007年本科毕业于北京大学地球与空间科学学院,2015年美国耶鲁大学地球物理学博士学位。2015年9月到2018年7月,在美国卡内基研究所从事博士后研究工作。从2018年9月开始,任中国科学院广州地球化学研究所任职。主要从事实验地球科学的研究。主要成果包括:(1)建立了一套新的快速加温的激光加热的金刚石压腔的系统,发展并完善了高压下二维温度分布测量的新方法。 (2) 测量了氧化镁矿物在下地幔的熔融曲线,解决了此矿物在高压下熔融温度的长期争议,并且为模拟地球深部熔融过程奠定了基础。(3) 首次用实验估测下地幔熔体的粘度,并提出了此核幔边界超低速层的新的形成机制。(4) 成功测量了镁元素在地核中的溶解度,发现其值随温度变化非常小,比之前研究结果大为不符,很大程度上否定了氧化镁出熔机制对早期地磁场的贡献。已发表国际SCI论文11篇,其中第一作者、独立作者及通讯作者SCI论文7篇。论文主要发表在Nature, Geophysical Research Letters, Earth and Planetary Science Letters, Review of Scientific Instruments上。社会任职:
