  The late Permian to Triassic sediments of the Solway Basin consist of a layer-cake succession of mature, predominantly fine-grained red clastics laid down in semi-arid alluvial plain to arid sabkha and saline marginal marine or lacustrine environments. The Cumbrian Coastal Group consists of Basal Clastics and Eden Shales. The Basal Clastics are thin regolith deposits resting unconformably Cited by: Plynlimon groundwaters 31 Teifi groundwaters 37 Rheidol groundwaters 44 Pollution indicators 54 6.

The aim of this article is to provide a qualitative and quantitative description of Lower–Upper Cretaceous detrital rocks (Escucha and Utrillas sandstones) in order to explore their potential use as CO2 reservoirs based on their petrographic and petrophysical characteristics.

The image below shows red sandstone in close up, with the constituent grains clearly visible. Red sandstones like this are found in several parts of England. They are made of small, rounded sand grains, and frequently show slanting beds (cross-bedding), like the ones in the photograph below. The shallowest one (depth: m) was installed at a contact between fine- and medium-grained sands. The next two piezometers (depths: and m) were set into medium-grained sands, and the deepest one (depth: m) was set into coarse-grained sands and gravels. The organic matter was accumulated within a peat layer with a thickness Cited by: 1.

Investigation of Colloid Stability Using a Simple Laser Light Scattering Device (~30nm) in diameter (e.g. Shaw, ). Although it was assumed that pure water is colloid free. The Triassic Sandstone as an aquifer The Triassic Sandstone forms the UK's second most important aquifer after the Chalk and consists of sandstones, conglomerates and marls up to m thick.

It can yield up to l/sec of good quality hard to moderately hard water from the upper parts of the aquifer.

The Triassic Sherwood Sandstone Group is a major UK aquifer. In this study the groundwater geochemistry of a 60 km 2 area has been investigated to improve the understanding of the hydrogeology of the area and to determine the origin of by: Manufactured nanoparticle movement in the groundwaters of a redbed sandstone: laboratory experiments and field observations An investigation into colloids in Triassic Sandstone groundwaters.

It is made up of quartz crystals held together in an iron oxide rich cement; this cement gives the rock its characteristic red colour. In rock exposures of red sandstone it is possible to see cross bedding in the rock formed by the wind as the sand dunes migrated.

Samples of Triassic Sherwood Sandstone Group aquifer material were taken from a quarry adjacent to the Burntstump landfill, north of Nottingham, Nottinghamshire.

Freshly excavated material was collected and air dried prior to use with no further processing. The sandstone is very friable and readily crumbled into loose sand, so the.

An Investigation of Complex Saline Groundwater Problems in the Permo Triassic Sandstones of North West England. Abstract. Long standing saline intrusion and connate saline groundwater problems are being studied in the Permo Triassic aquifers of North West by: 9. Groundwater in the Red River’s delta plain, North Vietnam, was found in Holocene, Pleistocene, Neogene and Triassic aquifers in fresh, brackish and saline types with a total dissolved solids (TDS) content ranging from less than 1 g L−1 to higher than 3 g L−1.

Towards prediction of saturated-zone pollutant movement in groundwaters in fractured permeable-matrix aquifers: The case of the UK Permo-Triassic sandstones UK Triassic Sandstone in the. Triassic rocks ( to million years ago) In the Triassic, Britain was part of the vast supercontinent of Pangaea, into which many of the world's landmasses were grouped.

Mountains, including the Mendips, created by uplift at the end of the Carboniferous were rapidly being eroded.

Fluvial sedimentary successions represent porous media that host groundwater and geothermal resources.

Additionally, they overlie crystalline rocks hosting nuclear waste repositories in rift settings. The permeability characteristics of an arenaceous fluvial succession, the Triassic St Bees Sandstone Formation in England (UK), are described, from core-plug to well-test scale up to ~1 km by: 7.

There are three reasons to study the occurrence of methane (CH 4) in groundwaters: (i) as part of the contribution to the atmospheric budget (‘emissions’), (ii) as a potential explosive hazard (‘safety’), and (iii) more fundamentally its production characteristics.

For the UK, emissions and safety have been addressed by Gooddy and Darling ().Cited by:. There are approximately licensed groundwater heating and cooling applications in the UK, of which approximately 25% are installed in Permo-Triassic sandstone.

The Permo-Triassic sandstones are extensively developed in the north of England, the midlands and to a smaller extent in the southwest, and are second only to the Chalk aquifer in terms of numbers of this type of application.[17] The tracer test was conducted in at the University of Birmingham, United Kingdom, in a Permo‐Triassic Sandstone aquifer.
