Cenozoic sedimentary and volcanic rocks of New Zealand: A reference volume of lithology, age and paleoenvironments with maps (PMAPs) and database. [PDF]
, 2015 This volume presents descriptive geological data and text about each Cenozoic sedimentary and volcanic geological unit to formation and member level (in some cases) exposed on land in New Zealand, including their lithology, stratigraphic age and inferred

Restoration Ecology, EarlyView.Abstract Introduction Process‐based restoration is novel in livestock production systems of the Northern Great Plains (NGP), and limited region‐specific evidence can impede adoption. We investigated the effects of methods such as beaver dam analogs (BDAs) on NGP plant communities.

Two models of hydrocarbon deposits formation in the South Caspian and Middle Kura Depressions
Геофизический журналThe model for the formation of hydrocarbon deposits in the South Caspian and Middle Kura depressions, despite a detailed study of the problem using geophysical and geochemical methods, remains a subject of debate.

Where geology meets pedology: Late Quaternary tephras, loess, and paleosols in the Mamaku Plateau and Lake Rerewhakaaitu areas [PDF]
, 2012 On this trip we focus on tephrostratigraphy and soil stratigraphy together with aspects of palaeoenvironmental reconstruction over long and short time-spans.

Sedimentology, EarlyView.ABSTRACT Thin ferruginous sandy crusts are common on top of sandstone beds in the Early Permian post‐glacial deposits of the Paraná Basin in southern Brazil. These crusts usually preserve wrinkle structures, suggesting that they might be a product of microbial mediation.

Sedimentology, EarlyView.ABSTRACT The c. 1 Ga Diabaig Formation of north‐west Scotland preserves diverse lacustrine and fluvial facies and abundant microbial and non‐microbial surficial sedimentary features. 172.6 m of section was logged across seven localities to assess the distribution of microbially induced sedimentary structures (MISS) relative to lithofacies, substrate ...

Sedimentology, EarlyView.ABSTRACT The integrated analysis of lithofacies, mineralogy and geochemistry of the hemipelagic marine succession exposed in La Cerradura section (South‐Iberian Palaeomargin) provides new information to characterise the palaeoenvironmental conditions during the latest Pliensbachian to early Toarcian, including the Jenkyns Event.

Mud Volcanoes - A New Class of Sites for Geological and Astrobiological Exploration of Mars [PDF]
Mud volcanoes provide a unique low-temperature window into the Earth s subsurface - including the deep biosphere - and may prove to be significant sources of atmospheric methane. The identification of analogous features on Mars would provide an important

Terra Nova, EarlyView.ABSTRACT The Paleoproterozoic Talvivaara mudstone is a very large sulfidic Ni‐Co deposit that records enhanced organic matter accumulation during the global Shunga Event. Here, rock geochemistry and microscale S and Fe isotope composition of in situ pyrrhotites and pyrites are studied in well‐characterised, well‐preserved drill core samples.
