Abstract

Abstract. Major glaciation in the Sierra Nevada of California resulted in the deposition of till which underlies latite 2.7 x 10(6) years old and overlies andesite 3.1 x 10(6) years old. This till, herein called the Deadman Pass till, is the oldest Pleistocene glacial deposit that has been found in temperate latitudes.

摘要。加利福尼亚内华达山脉的主要冰川作用导致了冰碛的沉积，这些冰碛覆盖在 2.7×10^6 年的粗面安山岩之上，又被 3.1×10^6 年的安山岩所覆盖。这块冰碛，本文称之为死人山口冰碛，是在温带地区发现的最古老的更新世冰川沉积物。
