Conference for the Third International Conference on the Geochemistry of the Earth Surface

1993年8月1日至6日将在宾夕法尼亚州大学公园举行一次关于地球表面地球化学的国际专题讨论会。本次研讨会是隶属于国际地球化学和宇宙化学协会的沉积物风化和成岩作用地球化学工作组（GWDS-3）的第三次会议。过去的会议曾在西班牙格拉纳达（1986年）和法国普罗旺斯艾克斯（1990年）举行。科学会议将涵盖地表地球化学的广泛主题：古气候和古土壤，从流域到全球尺度的化学风化和剥蚀，沉积物的早期成岩作用和有机地球化学，低温地球化学动力学，全球循环和环境地球化学。研讨会的一个突出主题将是（现代和古环境）地表地球化学研究在国际全球变化努力中的作用。过去的会议是真正的国际会议，我们将继续这一传统。此外，全球发展趋势-3鼓励学生和发展中国家科学家的参与。为了实现这些目标，我们要求国家科学基金会提供支持（主要用于学生和外国参与者的旅行和会议费用）。我们将支付杰出的外国受邀者的部分费用，并为学生和外国参与者建立一个nsf赞助的旅行援助奖。

An international symposium on the Geochemistry of the Earth Surface will be held at University Park, Pennsylvania on August 1- 6, 1993. The symposium is the third meeting of the Working Group on Geochemistry of Weathering and Diagenesis of Sediments, (GWDS-3) which is affiliated with the International Association of Geochemistry and Cosmochemistry. Past meetings have been held in Granada, Spain (1986) and Aix-en-Provence, France (1990). The scientific sessions will cover a wide range of topics in surficial geochemistry: paleoclimates and paleosols, chemical weathering and denudation at scales from the watershed to global, early diagenesis and organic geochemistry of sediments, geochemical kinetics at low temperatures, global cycles, and environmental geochemistry. A prominent theme of the symposium will be the role of surficial geochemical studies (of both modern and paleoenvironments) in the international global change effort. Past meetings have been truly international, and we will continue the tradition. In addition, the GWDS-3 encourages the participation of students, and of scientists from developing nations. To achieve these goals we are requesting support (primarily for travel and meeting expenses of students and foreign participants) from the National Science Foundation. We will defray part of the costs of the distinguished foreign invitees, as well as to establish a NSF-sponsored, travel assistance award for students and foreign participants.
