Using recent geologic mapping combined with
digital elevation data, aerial photo interpretation, and
cross section balancing, we describe the threedimensional
(3-D) geometry and kinematics of the
Nuncios Fold Complex in the Monterrey Salient of
northeastern Mexico. This map-scale, evaporite-cored
detachment fold structure involves Upper Jurassic
through Cretaceous rocks deformed during the
Laramide orogeny and comprises two westward
plunging anticlines and an intervening, eastward
plunging syncline. Seven balanced cross sections and
a 3-D model of this north vergent structure document
substantial along-strike variations in both fold
geometry and detachment depth, suggesting that 3-D
flow of the detachment layer may have occurred
during folding. Comparison of folds in the Monterrey
Salient with those in the neighboring Parras Basin
suggests that the latter south vergent folds root to a
shallower detachment. We suggest that northward
transport of the Monterrey Salient folds on the lower
evaporite detachment may have been inhibited by a
thick sequence of foreland basin rocks in the
northeastern Parras and southern La Popa basins and
that the smaller, south verging folds formed where the
lower detachment was abandoned and slip was
transferred to the shallower detachment, forming a
triangle zone at the front of the Sierra Madre orogenic
wedge
Deep underground neutrino experiment (DUNE) near detector conceptual design report

- Field of study
The Deep Underground Neutrino Experiment (DUNE) is an international, world-class experiment aimed at exploring fundamental questions about the universe that are at the forefront of astrophysics and particle physics research. DUNE will study questions pertaining to the preponderance of matter over antimatter in the early universe, the dynamics of supernovae, the subtleties of neutrino interaction physics, and a number of beyond the Standard Model topics accessible in a powerful neutrino beam. A critical component of the DUNE physics program involves the study of changes in a powerful beam of neutrinos, i.e., neutrino oscillations, as the neutrinos propagate a long distance. The experiment consists of a near detector, sited close to the source of the beam, and a far detector, sited along the beam at a large distance. This document, the DUNE Near Detector Conceptual Design Report (CDR), describes the design of the DUNE near detector and the science program that drives the design and technology choices. The goals and requirements underlying the design, along with projected performance are given. It serves as a starting point for a more detailed design that will be described in future documents. © 2021 by the authors. Licensee MDPI, Basel, Switzerland
Long-baseline neutrino oscillation physics potential of the DUNE experiment: DUNE Collaboration
- Publication venue
- Publication date
- 01/01/2020
- Field of study
The sensitivity of the Deep Underground Neutrino Experiment (DUNE) to neutrino oscillation is determined, based on a full simulation, reconstruction, and event selection of the far detector and a full simulation and parameterized analysis of the near detector. Detailed uncertainties due to the flux prediction, neutrino interaction model, and detector effects are included. DUNE will resolve the neutrino mass ordering to a precision of 5σ, for all δCP values, after 2 years of running with the nominal detector design and beam configuration. It has the potential to observe charge-parity violation in the neutrino sector to a precision of 3σ (5σ) after an exposure of 5 (10) years, for 50% of all δCP values. It will also make precise measurements of other parameters governing long-baseline neutrino oscillation, and after an exposure of 15 years will achieve a similar sensitivity to sin 22 θ13 to current reactor experiments. © 2020, The Author(s)
