Ludlow, Murchison and the Limestone Conundrum

October 17, 20151:26 pmJune 23, 2016 1:33 pm

In the mid Silurian, about 430 million years ago, the present day area of England lay at the north eastern margin of a continent called Avalonia. To the north lay the Iapetus Ocean and beyond that the continent of Laurentia; made up of parts of North America, Canada, Greenland and what would become Scotland. Continental […]

Wenlock Limestone

April 1, 201312:00 pmMay 26, 2016 9:30 am

Pale grey nodular or thinly bedded limestones. In character it varies markedly across the region. Examples from the Malvern Axis hills (Abberley, Suckley etc.), Ledbury and Woolhope Dome can be spectacularly fossiliferous, corresponding to reef bodies. During the Silurian water depth deepened towards open ocean to the west and around Ludlow the Wenlock limestone is […]

Bishop’s Frome Limestone

A calcrete, formed within the soil horizon during the Devonian, this rubbly limestone occurs at the boundary between the Raglan Mudstone and St Maughans Sandstone and is not widely used for building. Some use is made in Bishop’s Frome but generally it has been exploited for lime-burning. It also forms an important source for tufa […]

Aymestry Limestone

Blue-grey, hard, nodular argillaceous limestone. The presence of the strongly ribbed brachiopod Kirkidium knightii is diagnostic for this formation. Widely used in the Mortimer Forest, Woolhope Dome, Suckley Hills and Ledbury areas. The character of the formation, like most of the Silurian strata, can vary markedly between a massive limestone suitable for dimension stone to […]

Hidden History of Malvern College

Article by James Ferguson, a volunteer. After Great Malvern Priory, three of the most important stone buildings in Malvern are to be found in Malvern College: The first, the Main Building, is the work of the architect, Charles Hansom, in 1862; the second is the Chapel, by Arthur Blomfield in 1896; and the third, the […]

One of our big challenges on the Building Stones project is directly tracing a stone in a building to a quarry. Detailed fieldwork can be really effective for working out the range of rock types used and to give some idea of the areas these may have come from but, in general, for our project, […]

Eye spy an Earthcache

Earthcache is the perfect activity to enjoy the great outdoors, see some interesting geology, and test your knowledge. Why not have a go this summer… Go to www.earthcache.org Written by Dave Stadley, a Building Stones Volunteer.   A couple of years ago, we reported on the publication of our first Earthcache, a variety of Geocache.
