Deformation of continental crust along a transform boundary, Coast Mountains, British Columbia [PDF]

open access: yes, 2010
New structural, paleomagnetic, and apatite (U-Th)/He results from the continental margin inboard of the Queen Charlotte fault (~54°N) delineate patterns of brittle faulting linked to transform development since ~50 Ma.

A typology of schools across the four nations of the United Kingdom: Class, race and geography

open access: yesBritish Educational Research Journal, EarlyView.
Abstract In this paper we analyse the hierarchical field of schools across the United Kingdom during the transition to university and suggest that there are five socially distinct clusters of schools. Our five‐cluster typology of UK schools is composed of an established group of elite private and state schools, schools for the white rural and suburban ...

Correlating magnetic fabrics with finite strain : comparing results from mudrocks in the Variscan and Appalachian Orogens [PDF]

open access: yes, 2004
New magnetic anisotropy data from Variscan mudstones collected in the Cantabrian Arc, N Spain constrain the corresponding strain (shortening). The results are based on our previous study of mudrocks from the Valley and Ridge Province (Appalachians) where

Geology of the Variscan basement of the Laconi-Asuni area (central Sardinia, Italy): the core of a regional antiform refolding a tectonic nappe stack

open access: yes, 2015
The study area extends in central Sardinia between the coordinates 8°56′00″/39°55′00″ (NW corner) and 9°03′00″/39°50′00″ (SE corner). It forms part of the Sardinian Variscides that are characterized here by the western-most aspect of a regional structure

From Tin Mining to Green Tourism—Sungai Lembing's Inspiring Ecological Transformation

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Sungai Lembing, once a prominent tin mining town in Malaysia, faced severe environmental degradation and economic decline by the late 20th century due to unsustainable mining practices. This study explores Sungai Lembing's transformation from a mining hub to a model of ecological restoration and sustainable development through a governance‐led

Wetlands as environments of early human occupation: A new classification for freshwater palaeowetlands

open access: yesThe Depositional Record, EarlyView.
A new classification for inland freshwater palaeowetlands to be used in the field or core laboratory by sedimentologists, providing examples from the Guadix Basin (southern Spain). Abstract Present wetlands have proven to be delicate, biodiverse ecosystems, that are natural sinks for CO2 and act as good indicators for climate changes.

Fate of wastewater nitrogen upon injection into a coastal saline groundwater system, Florida Keys, USA

open access: yesThe Depositional Record, EarlyView.
Despite advanced wastewater treatment, dilution by rainwater and mixing, and microbial modification, nitrogen nutrients derived from shallowly injected wastewater are detected in nearshore waters in the Florida Keys. Abstract Injection of treated wastewater into the shallow subsurface on islands and along coastlines is a common practice in areas like ...
