Sedimentary Mercury Enrichments as a Tracer of Large Igneous Province Volcanism
Geophysical Monograph Series, Page 247-262., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Estratigrafía de Sr y evolución sedimentaria de los depósitos marinos del Mioceno temprano en el antepaís del norte de la Cuenca Austral (o Magallanes), Argentina [PDF]
, 2015 Early Miocene shallow marine deposits in the region of Lago Posadas-Meseta Belgrano (Argentina) represent part of the “Patagoniense” transgression, an Atlantic marine incursion that flooded large part of Patagonia, including the Austral (foreland) Basin (

The Depositional Record, EarlyView.This paper provides a new facies model of gravelly cyclic steps that includes a facies model of lee side and variations deposited from hyperpycnal and surge‐type high‐density turbidity currents. Abstract Gravelly cyclic steps formed by turbidity currents have recently been widely recognised in the geological record.

Unsupervised seismic facies classification using deep convolutional autoencoder [PDF]
arXiv, 2020 With the increased size and complexity of seismic surveys, manual labeling of seismic facies has become a significant challenge. Application of automatic methods for seismic facies interpretation could significantly reduce the manual labor and subjectivity of a particular interpreter present in conventional methods.

Anatomy and Sequence Architecture of the early Post-Rift in the Neuquén Basin (Argentina): A Response to Physiography and Relative Sea-level Changes [PDF]
, 2013 A detailed architectural and sequence stratigraphic analysis was carried out in the early-post-rift succession of central Neuque´n Basin (Middle Jurassic Cuyo Group), integrating outcrop and subsurface information from a 3,000 km2 area.

The Depositional Record, EarlyView.This study integrates and expands the U–Pb detrital zircon dataset from the Colton fluvial system to highlight spatial variations in provenance signals within the early Palaeogene infill of the south‐western Uinta Basin, in Utah. The provenance data sheds light on the origin of clastic sediment and on the relationship with potential palaeodrainage ...

Functional asymptotic confidence intervals for a common mean of independent random variables [PDF]
Electronic Journal of Statistics 2009, Vol. 3, 25-40, 2009 We consider independent random variables (r.v.'s) with a common mean $\mu$ that either satisfy Lindeberg's condition, or are symmetric around $\mu$. Present forms of existing functional central limit theorems (FCLT's) for Studentized partial sums of such r.v.'s on $D[0,1]$ are seen to be of some use for constructing asymptotic confidence intervals, or ...

The Depositional Record, EarlyView.Late Jurassic extension, footwall uplift, erosion and karstification of marine Jurassic carbonates in the western Cameros Basin (Spain) resulted in the deposition of ?Upper Kimmeridgian‐Tithonian syntectonic alluvial fan deposits and a series of ?Tithonian to Berriasian distal alluvial marls, palustrine, lacustrine and finally lagoonal carbonates.

Prima Facie Questions in Quantum Gravity [PDF]
, 1993 The long history of the study of quantum gravity has thrown up a complex web of ideas and approaches. The aim of this article is to unravel this web a little by analysing some of the {\em prima facie\/} questions that can be asked of almost any approach to quantum gravity and whose answers assist in classifying the different schemes.
