9406030 Selverstone Considerable progress has been made in understanding proterozoic terrane assembly in Wyoming and New Mexico, however an important spatial gap in information prevents on overall synthesis. This project in focused on exposures in the Big Thompson River area, Colorado where an unusually good opportunity exists to obtain pressure-temperature-time information by virtue of variable metamorphic grade and suitable lithology. Results should provide a more comprehensive account of the processes involved in the assembly of crustal blocks and their addition to cratonic North America.

小行星9406030 在理解怀俄明州和新墨西哥州的元古宙古生物组合方面取得了相当大的进展，然而，信息的重要空间差距阻碍了全面的综合。 该项目的重点是科罗拉多大汤普森河地区的暴露，由于变质程度和合适的岩性，该地区存在获得压力-温度-时间信息的非常好的机会。 研究结果应能更全面地说明地壳块体的组合过程及其在北美板块中的添加。
