The origin of massive sandstone facies in an ancient braided river deposits [PDF]

open access: yes, 1995
Lateral profiling techniques have been utilised to define the three-dimensional fluvial architecture of the Fell Sandstone Group (Arundian-Holkerian) of the Northumberland Basin, UK; the Lee-type sandstones (Morrowan-Atokan) of the central Appalachian ...

Facies mosaic in the inner areas of a shallow carbonate ramp (Upper Jurassic, Higueruelas Fm, NE Spain) [PDF]

open access: yes, 2018
The internal facies and sedimentary architecture of an Upper Jurassic inner carbonate ramp were reconstructed after the analysis and correlation of 14 logs in a 1 × 2 km outcrop area around the Mezalocha locality (south of Zaragoza, NE Spain).

Q-Facies: A tool for the quantitative interpretation of groundwater hydrochemical facies

open access: yesSoftwareX, 2023
This article presents Q-Facies, an open-source Python package for quantitative analysis of hydrochemical facies (HF). HF is widely used to interpret the chemical characteristics of groundwater. However, it is difficult to analyse its spatial or temporal variability due to its qualitative nature and the small number of classes.
