Lower Tertiary Alluvial Paleosols and Processes of Ancient Floodplain Construction

9303959 Kraus PI将研究始新世和渐新世冲积古土壤，以验证崩解模型（洪泛平原重建的新概念），并阐明古土壤/景观关系，这对解决冲积盆地的沉积、气候和构造历史至关重要。由于土壤是冲积景观的一个组成部分，崩裂模型也为研究冲积平原重建与冲积古土壤横向和垂直分布之间的关系开辟了新的思路。PI将比较两种不同的盆地环境和两种不同的气候环境下的古土壤，以阐明构造、沉积速率和气候对古土壤形成的影响。＊＊＊

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. ***
