9303959 Kraus PI will study Eocene and Oligocene alluvial paleosols to test the avulsion model (a new concept of floodplain reconstruction) and to clarify ancient soil/landscape relationships, which are critical for resolving the depositional, climatic and structural histories of alluvial basins. Because soils are an integral part of the alluvial landscape, the avulsion model also opens new lines of inquiry into the relationship between floodplain reconstruction and the lateral and vertical distributions of alluvial paleosols. PI will compare paleosols from two different basinal settings, and also from two different climatic settings, in order to elucidate the influences of tectonics, sedimentation rate, and climate on paleosol formation. ***

小行星9303959 PI将研究始新世和渐新世冲积古土壤，以测试撕脱模型（洪泛区重建的新概念），并澄清古代土壤/景观关系，这对于解决冲积盆地的沉积，气候和结构历史至关重要。 由于土壤是冲积景观的一个组成部分，撕脱模型也开辟了新的调查线河漫滩重建和冲积古土壤的横向和垂直分布之间的关系。 PI将比较来自两个不同盆地环境和两个不同气候环境的古土壤，以阐明构造、沉积速率和气候对古土壤形成的影响。 ***
