Abstract: A comprehensive hydrogeological understanding of the deep Upper Jurassic carbonate aquifer, which represents an important geothermal reservoir in the South German Molasse Basin (SGMB), is crucial for improved and sustainable groundwater resource management. Water chemical data and environmental isotope analyses of δD, δ18O and 87Sr/86Sr were obtained from groundwater of 24 deep Upper Jurassic geothermal wells and coupled with a few analyses of noble gases (3He/4He, 40Ar/36Ar) and noble gas infiltration temperatures. Hierarchical cluster analysis revealed three major water types and allowed a hydrochemical zoning of the SGMB, while exploratory factor analyses identified the hydrogeological processes affecting the water chemical composition of the thermal water. Water types 1 and 2 are of Na-[Ca]-HCO3-Cl type, lowly mineralised and have been recharged 87 86 under meteoric cold climate conditions. Both water types show Sr/ Sr signatures, stable water isotopes values and calculated apparent mean residence times, which suggest minor water-rock Citation: Heine, F.; Zosseder, K.; interaction within a hydraulically active flow system of the Northeastern and Southeastern Central Einsiedl, F.

Groundwater Storage Dynamics in the World's
Interactive comment on “Groundwater storage dynamics in the world’s large aquifer systems from GRACE: uncertainty and role of extreme precipitation” by Mohammad Shamsudduha and Richard G. Taylor Marc Bierkens (Referee #1) [email protected] Received and published: 2 January 2020 Reviewer’s comments are italicised, and our responses (R) and revisions (REVISION) are provided in normal fonts. General comments The authors use the results of three different GRACE-based TWS methods and 4 Land surface models to generate an ensemble of groundwater storage anomalies. These are subsequently analyzed by a non-parametric statistical method to separate seasonal signals from non-linear trends and residuals. The main message of the paper is that trends in GWS anomalies (ΔGWS), if existing, are non-linear in the vast majority of main aquifer systems and that rainfall anomalies play an important role in explaining these non-linear trends. I enjoyed reading the paper. I find that it is a well-written with an important message that deserves publication. However, I have a few comments. Moderate comments: 1. I find the lack of reference to estimates based on global hydrological models (GHMS) remarkable. The first spatially distributed global assessment of depletion rates where based on such models and, albeit indirect, should be used in the discussion. They are the basis for the “narratives on global groundwater depletion” that are mentioned in the discussion and the abstract (See https://iopscience.iop.org/article/10.1088/1748- 9326/ab1a5f/meta for an overview of these studies). This is the more remarkable, given that the authors do use Land Surface Models (LSMs) to estimate ΔGWS from GRACE ΔTWS. -

The Hell Creek Formation, Montana: a Stratigraphic Review and Revision Based on a Sequence Stratigraphic Approach
Review The Hell Creek Formation, Montana: A Stratigraphic Review and Revision Based on a Sequence Stratigraphic Approach Denver Fowler 1,2 1 Badlands Dinosaur Museum, Dickinson Museum Center, Dickinson, ND 58601, USA; [email protected] 2 Museum of the Rockies, Montana State University, Bozeman, MT 59717, USA Received: 12 September 2020; Accepted: 30 October 2020; Published: date Supporting Information 1. Methods: Lithofacies Descriptions Facies descriptions follow methodology laid out in Miall (1985). Descriptions mostly follow those of Flight (2004) for the Bearpaw Shale and Fox Hills Sandstone. Additional lithofacies are described for the Colgate sandstone, ?Battle Formation, an undivided Hell Creek Formation, and the lowermost 5–10 m of the Fort Union Formation. It was desirable to stay as close to Flight's (2004) definitions as possible in order to facilitate cross comparison between measured sections and interpretation; however I have also chosen to remain true to the intentions of Brown (1906) in keeping the Basal Sandstone (and associated basal scour) as the first unit of the Hell Creek Formation, rather than the tidal flats identified by Flight (2004). This analysis is not as concerned with the nature of the basal contacts as much as internal stratigraphy within the Hell Creek Formation itself, hence some of the stratal and facies relationships described by Flight (2004) were not directly observed by myself, but I have included them here to ease comparisons. 1.1. Bearpaw Shale The Bearpaw Shale is the basalmost formation considered in this study; as such only the uppermost 10–20 m have been observed in outcrop. In this upper 20 m or so, the Bearpaw Shale generally coarsens upwards, predominantly comprising shale with occasional interbedded sandstone. -

F I N a L Mineral Assessment Report
BLM F I N A L MINERAL ASSESSMENT REPORT Battle Mountain District Office - Nevada J A N U A R Y 2 0 1 2 This page intentionally left blank Bureau of Land Management Mineral Assessment Report SUMMARY The Bureau of Land Management (BLM) Battle Mountain District Office (BMDO) is in the process of revising the district’s Resource Management Plan (RMP). As part of the RMP revision process, the BLM is required to prepare a Mineral Assessment Report providing information regarding mineral occurrences and potential within the BMDO Planning Area (planning area). This report provides an intermediate level of detail for mineral assessment as prescribed in BLM Manual 3060 (BLM 1994). Information presented in this report will be summarized and incorporated into an Environmental Impact Statement (EIS) for the proposed RMP and into the final RMP. The geologic history of central and southern Nevada and the planning area is very complex and includes two major cycles of sedimentation (western and eastern facies sources), episodic thrust faulting, mountain building, and associated intrusive and igneous activity. More recent geologic history includes a period of crustal extension that was accompanied by bimodal (rhyolite-basalt) volcanism, large volume caldera volcanism, and basin and range block-faulting resulting in high-levels of shallow crustal heat flow. The regional and local geologic setting has been instrumental in the location of and potential for numerous economic metallic mineral deposits in the planning area, as well as development of economic geothermal resources. MINING AND MINERAL ACTIVITY IN NEVADA Mineral exploration, particularly for gold, is an ongoing enterprise in Nevada by both operators of existing mines and by other exploration companies. -

Structural Reconstruction of Copper Basin, Battle Mountain District
STRUCTURAL RECONSTRUCTION OF THE COPPER BASIN AREA, BATTLE MOUNTAIN DISTRICT, NEVADA by David A. Keeler A Prepublication Manuscript Submitted to the Faculty of the DEPARTMENT OF GEOSCIENCES In Partial Fulfillment of the Requirements for the Degree of MASTER OF SCIENCE In the Graduate College THE UNIVERSITY OF ARIZONA 2010 1 Structural Reconstruction of the Copper Basin Area, Battle Mountain District, Nevada David A. Keeler* Newmont Mining Corp. P.O. Box 1657, Battle Mountain, NV 89820-1657 and Eric Seedorff Institute for Mineral Resources, Department of Geosciences University of Arizona, Tucson, AZ 85721-0077 *Corresponding author: email, [email protected] 2 Abstract The Copper Basin area of the Battle Mountain district in north-central Nevada contains a porphyry Mo-Cu deposit (Buckingham), several porphyry-related Au ± Cu deposits in skarn and silica-pyrite bodies (Labrador, Empire, Northern Lights, Surprise, Carissa), and three supergene Cu deposits (Contention, Sweet Marie, Widow). This study uses the results of field mapping, U- Pb dating of zircons from igneous rocks, and structural analysis to assess the age, original geometry, depth of emplacement, and degree of tilting and dismemberment of the Late Cretaceous and Eocene hydrothermal systems the Copper Basin area and the source of the supergene copper. The Copper Basin area consists primarily of clastic rocks of the Cambrian(?) Harmony Formation overlain unconformably by Pennsylvanian-Permian clastic and carbonate rocks of the Antler overlap sequence. On the eastern side of Copper Basin, the Antler overlap sequence is overlain by the late Eocene tuff of Cove Mine, in which the compaction foliation dips 15 to 25° east. -
Walking on Water- Global Aquifers
16 March 2011 Walking on Water Mendel Khoo Researcher FDI Global Food and Water Crises Research Programme Gary Kleyn Manager FDI Global Food and Water Crises Research Programme Summary Aquifers play a key role in the provision of water for farming and for consumption by animals and humans. Almost all parts of the global landmass hide a subterranean water body. Aquifers are underground beds or layers of permeable rock, sediment or soil where water is lodged and can be accessed to yield water. This paper explores some of the major aquifers around the world and determines how countries are coping with increased water usage. Analysis Studying aquifers presents a number of problems, in part because scientists are yet to develop a complete picture of the globe’s aquifer systems; the sub-surface geology still holds mysteries. Further discoveries of aquifers and information on their connectivity with surface water can be expected in the future. The process should be similar to the way in which new discoveries of energy sources beneath the earth’s surface are still being made. An additional impediment lies in the different terms used to describe aquifers, some of them arising simply because of language differences. Aquifers do not fit into one neat category, as there are many variations to their form. The terminology for aquifers can include: underground water basins; groundwater mounds; lakes and parts of rivers; as well as artesian basins, which are confined aquifers contained under positive pressure. Hence, aquifers are not only located underground but some, or all, parts may also be found on the surface. -
