In the nineties, geochemists turned more and more to cosmochemistry, the geochemical study of extraterrestrial (ET) material. It seemed to many that mantle geochemistry was going round in circles and was no longer the branch of geochemistry where paradigm changing discoveries could be made. This was quite arrogant and inexact, as new concepts and novel tools including terrestrial extinct radioactivities and chemical geodynamics turned out to still have good days ahead. New instruments were being delivered to the CRPG, starting with the Cameca IMS 1970 large sector ion probe, the first model ordered by Etienne Deloule and Marc Chaussidon. Guy...

5.月球挥发性：氮同位素变异性的长期问题和月亮中挥发性物质的来源

在90年代，地球化学家越来越多地转向宇宙化学，这是地球外物质（ET）的地球化学研究。在许多人看来，地幔地球化学正在绕圈旋转，而不再是可以进行范式变化发现的地球化学分支。这是非常傲慢和不精确的，因为新的概念和新工具（包括地球灭绝的放射性和化学地球动力学）被证明还有很长的路要走。从Cameca IMS 1970大扇区离子探针开始，新仪器已交付给CRPG，这是Etienne Deloule和Marc Chaussidon订购的第一个模型。伙计
