Abstract
William Phipps Blake (1826–1910) and Thomas Antisell (1817–1893) served as geologists on Pacific Railroad Surveys undertaken in California during 1853–1855 for the purpose of determining feasible railroad routes. They produced some of the earliest geologic accounts, maps and cross sections for the region, for which surveying parties assessing right-of-way grades provided a fair amount of topographic control. They also produced a regional stratigraphy, chiefly lithology-based but with some biostratigraphic control for Cenozoic map units. The extent of Neogene uplift of the Coast Ranges and of Pleistocene lakes in the Mojave Desert region was recognized according to elevated shorelines and orogenic activity by recent volcanism and earthquake activity.
William Phipps Blake（1826–1910）和Thomas Antill（1817–1893）在1853–1855年间在加利福尼亚州进行的太平洋铁路调查中担任地质学家，目的是确定可行的铁路路线。他们为该地区制作了一些最早的地质账目、地图和横截面图，评估路权等级的测量方为其提供了相当多的地形控制。它们还产生了区域地层学，主要基于岩性，但对新生代地图单元有一些生物地层学控制。莫哈韦沙漠地区海岸山脉和更新世湖泊的新近系隆起程度是根据近期火山活动和地震活动引起的海岸线升高和造山活动而确定的。
