Three senior U.S. scientists, S. R. Riggs (East Carolina University), R. E. Garrison (U.C. Santa Cruz), and J. A. McKenzie (University of Florida), in addition to the principal investigator, will work with Dr. R. J. Cook, Chief of the Division of Continental Geology of the Bureau of Mineral Resources in Canberra, and colleagues in a project aimed at increasing our understanding of the nature and origin of sedimentary phosphate deposits in various on- and off-shore areas of Australia. This knowledge may shed light on the use of phosphorites to explain how major chemical and biological changes occur through geologic time. Phosphate deposits in Australia will be studied both in the field and in the laboratory through sedimentological and geochemical research methods jointly by the U.S. and Australian scientists. Such questions as: how phosphates are precipitated to form phosphorites; whether the biota of phosporites is unique; under what depositional conditions phosphorites are formed; what chemical/biochemical processes are involved in the weathering of phosphorites; and, whether the processes involved in the formation of phosphorite have varied over time, will be addressed. The Australian and U.S. groups have complementary expertise for this study, and both sides will benefit from a synergetic approach. The project fulfills the Program's objective of supporting research of scientific benefit both to Australia and the United States, and of providing access for U.S. scientists to the research environments and expertise of their Australian colleagues. The research propsed here extends studies being conducted by the investigators under other NSF grants (e.g., OCE 85-20724), to include _ _ data on Australian phosphates, and the use of various cross- disciplinary techniques available in Australia. This award provides travel and subsistence for one trip to Australia for each of the four senior researchers involved in the work. Results of the proposed research should lead to increased understanding of the processes involved in the evolution of the earth. In addition, both Australian and U.S. investigators will benefit from bringing the varied experimental techniques of sedimentology, paleobiology, oceanography, microbial ecology, and remote sensing to problems of this type. The project will take place under the aegis of the Agreement betweeen Australia and the United States for Scientific and Technical Cooperation.

除了首席研究员外，三名美国资深科学家--东卡罗来纳大学的S·R·R·里格斯、加州大学圣克鲁斯分校的R·E·加里森和佛罗里达大学的J·A·麦肯齐将与堪培拉矿产资源局大陆地质部主任R·J·库克博士合作。该项目旨在增加我们对澳大利亚各种陆上和近海地区沉积磷矿的性质和成因的了解。这一知识可能有助于阐明如何使用磷岩来解释如何在地质时间内发生重大的化学和生物变化。美国和澳大利亚科学家将通过沉积学和地球化学研究方法，在野外和实验室对澳大利亚的磷矿进行研究。将讨论以下问题：磷酸盐如何沉淀形成磷矿；磷矿的生物群是否独特；磷矿是在什么沉积条件下形成的；磷矿的风化涉及哪些化学/生化过程；以及磷矿形成的过程是否随着时间的推移而变化。澳大利亚和美国的研究小组在这项研究中拥有互补的专业知识，双方都将从协同方法中受益。该项目实现了该计划的目标，即支持对澳大利亚和美国都有科学利益的研究，并为美国科学家提供接触其澳大利亚同事的研究环境和专业知识的机会。这里提出的研究扩展了调查人员在其他国家科学基金会拨款(例如，OCE85-20724)下进行的研究，包括关于澳大利亚磷酸盐的数据，以及澳大利亚可用的各种跨学科技术的使用。该奖项为参与这项工作的四名高级研究人员每人提供一次澳大利亚之行的旅费和生活费。拟议的研究结果应有助于加深对地球演化过程的了解。此外，澳大利亚和美国的研究人员都将受益于将沉积学、古生物学、海洋学、微生物生态学和遥感等各种实验技术应用于这类问题。该项目将在澳大利亚和美国科学技术合作协定的支持下进行。
