The U.S. Geological Survey (USGS) quantitatively assessed the potential for unconventional (continuous) oil and gas resources within two Paleozoic organic-rich shales in the Tarim Basin of China (figs. 1 and 2): Lower Cambrian Yuertusi Formation and shales in the Middle Ordovician Series. These strata are the principal source rocks for conventional oil and gas fields in the interior of the Tarim Basin (Li and others 2018; Zhu, Chen, and others, 2018). The Tarim Basin, the largest petroleum basin in China, encompasses 563,000 square kilometers (km), and its Phanerozoic strata are as much as 16 km thick (Qiu and others, 2012). Although numerous oil and gas fields have been developed along its northern margin and in several uplifts in the basin’s interior, large parts of this remote basin remain unexplored. The USGS previously assessed the Tarim Basin’s conventional oil and gas resources (Charpentier and others, 2012). Paleozoic marine formations are currently preserved at depth and locally exposed around the basin’s periphery. They were deposited on the passive margin of the Tarim craton, a continental fragment proximal to the Gondwana margin. Since the late Paleozoic assembly of Central Asia, the Tarim Basin has been a vast nonmarine basin bounded on the south by the Tibetan Plateau and on the north by the Tien Shan. From the Carboniferous to the present, the basin’s margins have been strongly influenced by contractional deformation, including the ongoing Himalayan orogeny. This tectonic history has resulted in a relatively cool geothermal setting throughout the basin’s history; the current geothermal gradient is in the range of 20–23 degrees Celsius per km (Zhang, Huang, and others, 2015). Geologic Background
美国地质调查局(USGS)定量评估了中国塔里木盆地两个古生代富有机质页岩中非常规(连续)油气资源的潜力(图2)。1和2):下寒武统玉尔图斯组和中奥陶统页岩。这些地层是塔里木盆地内部常规油气田的主要烃源岩(Li等2018;朱、陈等人，2018)。塔里木盆地是中国最大的含油气盆地，面积达56.3万平方公里，显生宙地层厚度达16公里(Qiu等，2012)。尽管沿其北部边缘和盆地内部的几个隆起已经开发了许多油气田，但这个偏远盆地的大部分地区仍未被勘探。美国地质调查局此前对塔里木盆地的常规油气资源进行了评估(Charpentier等，2012)。古生代海相地层目前保存在盆地的深处，局部暴露在盆地周边。它们沉积在塔里木克拉通的被动边缘，这是一个接近冈瓦纳边缘的大陆碎片。自中亚晚古生代组合以来，塔里木盆地一直是一个南接青藏高原、北接天山的巨大非海相盆地。从石炭纪到现在，盆地边缘一直受到收缩变形的强烈影响，包括正在进行的喜马拉雅造山运动。这种构造历史导致了整个盆地历史上相对凉爽的地热环境;当前地温梯度在20-23℃/ km (Zhang, Huang, and others, 2015)。地质背景

The U.S. Geological Survey (USGS) quantitatively assessed the potential for undiscovered, technically recoverable continuous (unconventional) and conventional oil and gas resources in the Reggane Basin Province of Algeria (fig. 1). The Reggane Basin is one of a series of North African basins that achieved much of their current structural configuration through late Carboniferous−Permian (Hercynian orogen) compressional deformation (Boote and others, 1998; Coward and Ries, 2003; Badalini and others, 2009). The basin is asymmetric with a steeply dipping, structurally complex northeastern margin associated with a sedimentary section that gradually thins and shallows to the southwest. Silurian and Devonian organic-rich shales are the major petroleum source rocks in the basin (Boote and others, 1998). Organic matter in both source rocks may have reached the thermal generation window for oil during Carboniferous burial; both source rock intervals reached the gas-generation window during the Late Triassic–Jurassic (Boote and others, 1998; Logan and Duddy, 1998; Makhous and Galushkin, 2003; Zuehlke and others, 2010; Jaeger and others, 2017). Only the southwestern margin of the basin remains in the oil-generation window (Arab and Djezzar, 2011). This assessment includes an evaluation of undiscovered continuous (shale oil, shale gas, tight gas) resources and conventional oil and gas resources.
美国地质调查局(USGS)定量评估了阿尔及利亚省Reggane盆地未发现的、技术上可开采的连续(非常规)和常规油气资源的潜力(图1)。Reggane盆地是一系列北非盆地之一，通过晚石石纪-二叠纪(海西造山带)挤压变形形成了目前的大部分构造形态(Boote等人，1998;科沃德和里斯，2003;Badalini等人，2009)。盆地不对称，东北缘陡倾，构造复杂，沉积剖面向西南逐渐变薄变浅。志留系和泥盆系富有机质页岩是盆地主要的烃源岩(Boote等，1998)。烃源岩有机质可能在石炭系埋藏时已达到油热生窗期;这两个烃源岩层段均在晚三叠世—侏罗纪时期达到生气窗口期(Boote等，1998;《Logan and Duddy》，1998;Makhous and Galushkin, 2003;Zuehlke等人，2010;Jaeger等人，2017)。只有盆地西南边缘仍处于产油窗口(Arab and Djezzar, 2011)。该评价包括对未发现的连续(页岩油、页岩气、致密气)资源和常规油气资源的评价。

The Earth Mapping Resources Initiative (Earth MRI; formerly known as 3DEEP) is planned as a partnership between the U.S. Geological Survey (USGS), the Association of American State Geologists (AASG), and other Federal, State, and private-sector organizations. The goal of the effort is to improve our knowledge of the geologic framework in the United States and to identify areas that have the potential to contain undiscovered critical mineral resources. Enhancement of our domestic mineral supply will decrease our reliance on foreign sources of minerals that are fundamental to the Nation’s security and economy. The intent of Earth MRI is to leverage the USGS’s existing relationships with States and the private sector to conduct state-of-the-art geologic mapping and airborne geophysical and topographic (lidar) surveys. Analyses of these datasets could point to potential buried critical mineral deposits.

U.S. Department of the Interior U.S. Geological Survey Fact Sheet 2019–3047 October 2019 Introduction The U.S. Geological Survey (USGS) quantitatively assessed the potential for undiscovered, technically recoverable continuous resources in organic-rich shales of the Permian Phosphoria Formation within the Southwestern Wyoming Province (fig. 1). The Phosphoria Formation represents a complex stratigraphic unit that was deposited in an oceanic embayment along the west-facing Permian continental margin (Sheldon, 1963). During Guadalupian time, cold, nutrient-rich currents from the north swept the embayment, resulting in deposition of phosphatic mudstone, organic-rich shale, and chert in what was otherwise a sediment-starved basin (Piper and Medrano, 1994; Carroll and others, 1998). The deepwater lithologies of the basin transition eastward to shallow-water shelf carbonates of the Permian Park City Formation and finally to continental red mudstone and evaporites of the Permian Goose Egg Formation. Much of the area with the deepwater facies of the Phosphoria Formation is within the Wyoming Thrust Belt Province, but there are deepwater deposits in which the Phosphoria Formation is as much as 10,000 meters (m) deep in the western part of the Southwest Wyoming Province. The purpose of this assessment is to estimate technically recoverable shale-gas resources within Phosphoria Formation shales.

H chub (Gila cypha Miller 1946), found only in the Colorado River Basin, was one of the first species to be given full protection under the Endangered Species Act of 1973. Habitat alterations, such as changes in flow and water temperature caused by dams, and the introduction of nonnative fish have contributed to population declines in humpback chub and other native fish. These habitat alterations provide ideal conditions for the nonnative sport fish, rainbow trout (Oncorhynchus mykiss Walbaum 1792). Managers have long sought to balance recovery of humpback chub with a viable rainbow trout fishery. However, finding this balance requires understanding how environmental conditions and rainbow trout have affected humpback chub populations. Recent findings indicate that the Colorado River can be managed for rainbow trout while maintaining a healthy humpback chub population in Grand Canyon National Park.
H chub (Gila cypha Miller 1946)，只在科罗拉多河流域发现，是1973年《濒危物种法案》下第一批得到全面保护的物种之一。栖息地的改变，如大坝引起的流量和水温的变化，以及外来鱼类的引入，导致了座头鲸和其他本地鱼类的数量下降。这些栖息地的改变为非本地的运动鱼类虹鳟鱼(Oncorhynchus mykiss Walbaum 1792)提供了理想的条件。长期以来，管理人员一直在寻求平衡座头鲸的恢复与可行的虹鳟鱼渔业。然而，找到这种平衡需要了解环境条件和虹鳟是如何影响座头鲸种群的。最近的研究结果表明，科罗拉多河可以管理虹鳟鱼，同时保持大峡谷国家公园内健康的座头鲸种群。

When rainfall is lower than normal over an extended period, streamflows decline, groundwater levels fall, and hydrological drought can occur. Droughts can reduce the water available for societal needs, such as public and private drinking-water supplies, farming, and industry, and for ecological health, such as maintenance of water quality and natural ecosystems. Recent droughts in the northeastern United States have highlighted the need for new scientific tools to forecast the probability of future droughts so water managers and the public can be better prepared for these events when they happen. Two recent U.S. Geological Survey (USGS) studies provide tools that can forecast the probabilities of summer droughts for streams (Austin and Nelms, 2017) and the probabilities of groundwaterlevel declines below specified targets or thresholds (Dudley and others, 2017). These tools provide promising methods for identifying and anticipating probable streamflow and groundwater droughts specific to the northeastern United States. USGS Water Science Centers in the northeastern United States have acted together to use these methods for numerous streamflow gages and groundwater-level monitoring wells, and to make the results of the analyses available on the world wide web. This fact sheet describes the drought forecasting techniques used in a study to predict droughts for streamflow and groundwater in the northeastern United States.
当降雨量长时间低于正常水平时，河流流量减少，地下水位下降，水文干旱就会发生。干旱可以减少可用于社会需求(如公共和私人饮用水供应、农业和工业)和生态健康(如维持水质和自然生态系统)的水。美国东北部最近发生的干旱突出表明，需要新的科学工具来预测未来干旱的可能性，以便水资源管理者和公众能够在这些事件发生时更好地做好准备。美国地质调查局(USGS)最近的两项研究提供了工具，可以预测夏季溪流干旱的概率(Austin and Nelms, 2017)和地下水位下降到指定目标或阈值以下的概率(Dudley等，2017)。这些工具为识别和预测美国东北部可能发生的河流和地下水干旱提供了有希望的方法。美国地质勘探局位于美国东北部的水科学中心已共同行动起来，将这些方法用于众多的流量测量和地下水位监测井，并将分析结果公布在万维网上。这份情况说明书描述了在一项研究中用于预测美国东北部河流和地下水干旱的干旱预测技术。
